Very good video, with lots of info & well delivered. I wonder how this channel flew under my radar (pun intended) for so long. Subscribed! 👍🏻 Now, I have a couple of things I'd like to point out if I may. 8:07 The circular thingy serves as a capacitor for the oscillator (high-frequency NPN transistor), not an antenna. The antenna is at the other side, & it's a common transmit/receive antenna. 10:44 Although the LED pins are correct (anode = longer), the internal electrodes are wrong (anode = smaller, not bigger). I'm pointing this out because I believe one should look at the internal electrodes to figure out polarity, instead of the external ones, since the latter can be cut. & if people learn it wrong from this video, they may run into problems in the future. 20:02 I'd pull the button Pin to LOW, instead of HIGH, for two reasons. - If you pull it HIGH, you're constantly sinking 0.5mA, regardless of the button's state. Yes, that current is negligible in this circuit, but I believe it's important to adopt "good habits" anyway. In the case of microcontrollers, taking their limited power capabilities into consideration is one of them. - It feels more intuitive to "send a signal" to the Pin when the button is pressed, instead of "disrupting a signal". I believe it's easier for less experienced tinkerers to understand too. From what I've read (I haven't tried them myself, yet), those sensors don't interfere with other GHz devices (routers etc). Apparently they don't interfere with each other either! So using BT shields should work well too.
Just watched your tutorial and set up a new rcwl-0516 as I watched. I bought 20 and the 1st one I tested works very well. It's set up in front of the TV pointing back at me and it is very responsive and stable behavior too. Great channel and tutorial. Thanks!
Always the best from DroneBot Workshop!!! I just received five RCWL-0516 modules from aliexpress with intentions of setting up security zones for my property , with this very helpful video I think this will be the start of something very interesting, thanks for the upload.
Perfectly explained! Thank you. I connected the sensor without Arduino to a "remote doorbell button". Battery operated, small size, can be placed wherever it suits. The bell then rings (or just the LED flashes) when someone enters the controlled zone. Works through walls and doors!
Hello !! I'm about to prepare myself in making an alarm for my workshop and garage, your video has been more than useful to my future project. Nice explainations and many details. Good Job, keep on instructing us !! Long life to your channel
Hi, this is the first time I've been here, I'm a retired electronics tech, Marines, not played with electronics much for twenty years, but collected some arduino oriented electronics, off ebay, and low and behold, here's how to use the very module I selected for a burglar/security alarm system for my home. Great teaching skills, very clear explanations, nice easy pace. I look forward to getting caught back up, at least as much as necessary. How did you know I bought that doppler radar device?
Very interesting and informative video. The RCWL-0516 is now on my list future projects. I also particularly appreciate the care and preparation put into the production, and the use of high quality video. Too often videos like this are made with low resolution video so that the code examples and diagrams are unreadable.
Thanks for all your videos, especially this one. It made it much easier for me working with the RCWL-0516 doppler sensor and it's application. I'm new for this type of module sensors. Thank's again. Mr.G ( PS:I would like to know more abut your newsletter !)
As always, you explained things that is easy to understand with actual example and links to the codes, docs etc.. Keep up the good works. Thank you! New subs here!
So useful I bought some! Thank you. A good, concise video. I attached the output signal to an optocoupler relay module and the relay switches, so that's good! I've also found that if you keep moving around, the sensor is always active so the relay stays on E.G. running a light bulb, alarm etc. turns off once movement stops. would be good for a self contained alarm/light/ device on its own without needing an Arduino (or Picaxe in my case) so saving a few quid!!!! thank you again, You"ve got a new subscriber :-)
Vos vidéos sont très intéressantes et vos explications très claires, avec un réel souci de pédagogie. En vous suivant, je m'améliore. Je vous remercie très sincèrement pour ce partage.
Excellent video! The speed of instruction is perfect for the average mind and the illustrations are precise and well-synced with the language. But why the dropping resistor? I built the circuit on a breadboard using a 3.3v LED to match the 3.3v level of the output pin. Also, LEDs come in varying voltage ratings; 3.3v being just one. I also want to try replacing the LED with a piezoelectric element to see if the output pin has enough grunt to drive it.
Excellent! Waiting for my sensors to arrive. Practical discussion of using PIR or ultrasound vs this radar sensor (range, false positives, penetration of glass windows, etc) will be addressed in my own experiments. It would be nice if the sensor did not stay on for two seconds so it could be rotated and data collected in many directions in real time. Thanks for your great projects, well explained, as always.
There are other microwave sensors out there that just output the raw data but they seem to be more difficult to operated. As these are so cheap, you could use two or more pointing to different directions?
Hi, First I have to say that I really enjoy your instructional videos. You are one smart cookie. Keep em coming :) Secondly, I purchased the RCWL-0156 sensor and wired it up, both on its own, and then to an UNO, as per your instructions. ( I have a fair bit of experience with Arduino, and everything related to it, so I am confident that I connected everything properly) . I used a 220 ohm resistor for the out pin to the led. My issue is that although the RCWL functions properly. (IE: The led lights up when the sensor senses movement), it only has a range of 2cm. It doesn't pick up anything further than that. I received 5 units in my order, and tested all of them, and they all have the same range (2cm). Has anybody else experienced the same issue. Any ideas as to what could be wrong. PS: I tested with 2 different power supplies, first the UNO, and then I hooked up my Korad KA3005D set first to 12 volts, then to 24 volts and 0.003 amps. The sensing range was the same for all tests. Could it be a bad batch of sensors ? Cheers, T
I looked at 3 different videos with the same wire diagram and the LED just keeps blinking on/off. I tried different boards and they are all doing the same thing (basic setup). What might be the issue?
i have a question what is the maximum distance of this sensor as i am thinking about making a cycle sensor for my bike to show me when vehicles are behind me and approaching me
I do not think you will be able to do that because as you are moving, the sensor will detect movement all the time. But if you were able to, tell us. :)
Hi. I need a sensor that detect when I´m in the same side of a door but it doesn´t when I in the other side of the door. ¿Does this card works like this? I want to make an indicator for a rest room, if someone is in, the light turns on automaticly, but if nobody is in the rest room it turns off
Thanks, broad coverage. Excuse my ignorance, but how would it be possible to power a AC 230V light bulb without the Arduino, viz as standalone solution for LED as you described from 10:00, indeed AC relays require 5V DC and with RCWL-0516 the ouput is 3.3V.
The ldr-resistor example would be great for a war droid at night in sleep mode.Working on a turret right now.A few gesture sensors paintball gun and some high grade steppers systems.Converting some old solar panels to power it.
Hi can you please point me in the right direction for the pcb terminal block. As the holes are very close together I don't want to buy the wrong ones. Thank you
Another side benefit of this circuit with remote is the microwaves knock out car key remotes , so if your car key is cloned no one can use it anyway cause the only way to open car is with key manually while the detector is running when you come back turn off microwave and you can open car again
Great stuff!..I bought some doppler modules, and was looking for a way to control their output for lighting a room.I need an arduino lol.. thanks for explaining in a great relaxed concise manner. Fantastic video :-)
I want te make a wireless sensor (on battery) for home assistant. Is there a way that the rf transmitter sends a “on” state when motion is detected without using the uno board? Just the sensor and de rf transmitter.
Allo and thank you very much for the great knowledge you share with us , my question about this microwave sensor is : Range ; is there a way to have a set range ,meaning ignore from X range and more but when movement is inside the set range then an action is taken ?
Thanks for an informative video - question I have is - how directional is the radar on the RCWL0516? Can one make it only detect in a narrow range as I am thinking of using it on a model railway layout and to trigger only when a train passes by ? - thanks
Hi Is there a way that you can detect a clay 6 inch pipe route by rattling inside it with a drill rod. I can make it rattle in this way as I can access at a point . How can I follow the sound under ground mbe 4 metres and see what direction it travels. Is there a cheaper way than the expensive imaging gear ?
Ive used this to detect if my cats are outside my door. Its hooked up to a transistor that turn on leds that light up a cat shaped 3dprinted figurine. Been working fine outside for a couple of years now.
I'm glad for this vid. I'm useing the 0516 with a GSM (A6) with a uno to make a alarm, I got the code for the 0516 right but to send a sms is a bit more difficult but getting there. I hope when I get to figure every thing out to make a video of what I did and also with the code but got to get the code for the sms right. But nice video
Hi all! Thank you Bill for that video. I have a problem with my chickens. They always come to my patio and make it dirty. My project is to create a forbidden zone. So, I experimenting with a system to chase them away. I plan to use the product shown in this video to pilot two perpendicular air jets. These streams should be oriented on each side like a barrier and start simultaneously when a bird approches. To synchronize the actions, I wonder if that way of proceeding is a relevant choice in terms of sensitivity and speed. If someone has an idea or an experience, I'm interested. I look forward to reading you. Thank you very much. Philippe
Good video. I attempted to use one of these RCWL-0516 sensors with an ESP32 (client) configured to send the motion detected via ESP-NOW to another ESP32 (server). Unfortunately I’ve come across a small problem. The Wi-Fi function of the ESP32 causes false triggering of the RCWL-0516 if it is in close proximity to the ESP32. I don’t thinking it is the sending of the ESP-NOW messages causing the problem but when the ESP32 module comes out of deep sleep and the Wi-Fi initialises.
I have been trying to build a burglar alarm for my motorcycle to prevent people from stealing gas and so far have been unsuccessful. I have tried PIR and RCWL-056 and a few of the other sensors from your site. I have determined for my use, a touch sensor circuit would work best but cannot conceive how to use the motorcycle frame as the sensor. The pir has too many false alarms as does the RCWL. I already have a motion detector commercial alarm but it is not reliable as sometimes you have to really smack the bike to alarm it. I have tried using an arduino touch library but when i add a small metal grid the arduino cannot detect my touch. This type of alarm seems to be available commercially but I would like to build it. It would be great if you could build a project like this to demonstrate this alarm for either a motorcycle or a car.
Arduino Programme for Microwave to figure out hidden human bodies movement in a room with weapons , visibilty on a screen/camera like skeltons. Pl sir find out something like that
I have an enclosed dark area and today turn the lights on by magnetic reed switch but they frequently fail due to mounting issues. This solution seems better but I need to switch on 12V Leds of several watts. I suspect all I need is a relay (SSR?) instead of the LED or perhaps a MOSFET. Also, what would be the least expensive size arduino that could work. I also saw a reference to nodemcu and/or esp8266. I live in an RV so have lot's of 12V and a supply of buck-boost modules that can output 3 to 40V. Advice?
Is there something we can do about the sensitivity of the sensor? I live in a city and when one of my neighbors move, the alarm is set. Even three houses away from my house and through walls.
My understanding, from the product description at www.amazon.com/gp/product/B07MTWZDQZ/, is that you can solder a 1 M-ohm resistor on the bottom side (the R-GN points) to decrease the sensitivity.
since this rcwl-0516 can detect object from above, beneath, left and right, and how can one/the arduino knows where the object is moving from ??? thanks for your time and your input and this tutorial;
I bought several of these in the past to use as room proximity sensors. I intended to install them in the basement facing upwards to detect movement in rooms above. I thought I would be able to block motion detection below by using several layers of sheet metal, therefore only detecting motion above. I was unable to every get it limited in the way I desired. I wish it was possible to adjust these to direct the microwaves in just one direction. Any tips or do this type of experiment? Perhaps I wasn't using large enough sheets of metal.
I'm having problems with these modules. In the stand-alone mode, upon power on, the output goes high for three seconds, off for 10 seconds, then back on for three seconds. After that, the output remains off regardless of any motions. I tried three out of the eight I got...same behavior. Any suggestions?
probably manufacturing defect. I have few of those in diy lamps, no issue in months I have them in use. by default without caps they would go on every 2 seconds roughly and stay on for that long. I addad caps and ldr so detection only works at night, once movement is detected light is on for 1 minute
I just discovered this sensor last week, its very neat! I'm surprised its taken me this long to realize it exists as it seems to be a fantastic replacement to a conventional PIR sensor, and equal or better costwise as well. In fact now I'm wondering why anyone would use PIR when this is available. Can you (or anyone) breakdown any pros/cons between the two? So far it seems like a no brainer to go with this instead.
One corn i observed was this sensor is sensitive for motions beyond the walls or even doors so its not good if you are placing this on a wall to monitor motion within a particular room.
Hi, is there any sensor that can detect stationary humans ? And if yes, then can you please explain how to interface it with Arduino UNO microcontroller. Kindly let me know - I am working on a project that requires stationary human contactless detection.
This entire channel is gold.

I wish it was possible to adjust these to direct the microwaves in just one direction. Any tips or do this type of experiment? Perhaps I wasn't using large enough sheets of metal.
i have the same prpblem. if some one walking on the street it gives an alarm.
Thank you for all these excellent videos.
Can you do one on the LD2410C radar?
Excellent video. 90% of what i need to do in my project....
Thank you very much, Bill.
Very easy to learn type video. I like it so much thanks
Sir is there such a sensor which can identify the vehicle in the range of 1 kilometer and tell us that it is yh kitane distence urgent, alert it.
I'm having problems with these modules. In the stand-alone mode, upon power on, the output goes high for three seconds, off for 10 seconds, then back on for three seconds. After that, the output remains off regardless of any motions. I tried three out of the eight I got...same behavior. Any suggestions?
probably manufacturing defect. I have few of those in diy lamps, no issue in months I have them in use. by default without caps they would go on every 2 seconds roughly and stay on for that long. I addad caps and ldr so detection only works at night, once movement is detected light is on for 1 minute
Can you tell me please how can I reduce the range of senzor? I tried with 1 Mega ohm resistor but I reduce only a sensitivity but a little bit.
Many thanks for this very interesting video.
I just discovered this sensor last week, its very neat! I'm surprised its taken me this long to realize it exists as it seems to be a fantastic replacement to a conventional PIR sensor, and equal or better costwise as well. In fact now I'm wondering why anyone would use PIR when this is available. Can you (or anyone) breakdown any pros/cons between the two? So far it seems like a no brainer to go with this instead.
One corn i observed was this sensor is sensitive for motions beyond the walls or even doors so its not good if you are placing this on a wall to monitor motion within a particular room.
How would I add piezo speaker as well as led light?
Can it be placed in a enclosure and does that change the range and angle of detection
can you leave on when is percent and off when is not present thank
Is there away to keep the light on at night and turn off during the day?
Can u show the rcwl 0516 to trigger a 12v directly? Ie without Audrina
I have a question. Could It Be used to detect infrared emitters that are pointed out towards the sensor? Thank
Very nice explanation
Hi, is there any sensor that can detect stationary humans ? And if yes, then can you please explain how to interface it with Arduino UNO microcontroller. Kindly let me know - I am working on a project that requires stationary human contactless detection.
