- Proximity sensing is a very common application in electronics.
There are several ways to accomplish this. The most common way is by using a PIR sensor. PIR Sensor senses the change in ambient infrared radiation caused by warm bodies. I have already covered this in my Tutorial No. 5: "PIR Sensor Tutorial - With or Without Arduino". However, since PIR sensors detect movement from living objects, they can generate false alarms. These sensors are also inefficient in hot environments, as they rely on heat signatures.
The other common methods of proximity sensing involve, using reflected ultrasonic or light beams. Using these sensors, the intruding object is detected by the reflected beam back to its source. The time delay between transmission and reception is measured to calculate the distance to the object.
In this tutorial, we are going to look at another method of proximity sensing using "Microwaves" and "Doppler Effect". In my hand is an inexpensive RCWL-0516 Microwave Radar Motion Sensor. The RCWL-0516 microwave sensor detects "any movement" from "any object" and does not rely on heat, making it more reliable in hot environments. I am going to use this sensor to create a geo-fence around my house to detect motion and get notifications.

Great break down of the component, you're a decent educator.
Thanks
This is such a great motion sensor. I'm glad you are showcasing this one
Glad you like it!
I'm truly amazed by your video, keep going!
Cheers thanks
this is by far the most detailed explanation of all jump pins. I'm just looking for a proper method to block or direct the microwave sinced my cats and dogs constantly triggers it. i don't have to even ask as you answers all of my questions in the end.
i only have just one. i used it to trigger a mosfet switch for a battery indicator since i don't want the digital display to always illuminated. I'm glad i can shorten the trigger distance as it suites my purpose. thank you
Thanks a lot
I am glad that I was able to help you
My kit has only 2-3 CM detection how to increase
Very comprehensive tutorial... Excellent...👍👍👍
Thanks
Great video very detailed. Thanks a lot.

Very well explained...thanks
You are welcome
Superb explanation. Thanks
You are welcome
Fantastic. Thanks
Glad you liked it!
Very nice ,🙏
Thanks a lot
Excellent! can you please make a video on HB100.
Sure mate
I have few other videos in line
I will do one once I publish all my pending ones
Thanks again
i cant wait it too@@CrazyCoupleDIY
Its amazing sensor...i have one question. If i want to switch on approx 8 to 10 minutes, then only big capister like 1000uf 25volt is enough or we required 555 ic timer circut?
I have it hooked up like in your diagram at 11:58; the LED just blink on/off and not triggering when I wave my hand. What could be the issue?
My opinion. I have been using this sensor for some time now. I wanted to use this as a replacement for PIR. The only problem is that it can detect from behind thin walls and it triggers false alarm and also it uses much more power than a PIR because it is a continuous wave so if you install somewhere that you wanna rely on battery, it is not recommended. As a whole it is not recommended for security presence detection. It is more suitable for stairway lighting control.
I agree to the power consumption bit, but you can delimit your detection area by using aluminium foil.
Just sample it every x second... Why run it continuous on battery?
Hi! Can it detect moving vehicles at 10-12 meters?
Hello,
I appreciate your video; it was very useful. I also have a question about the sensor's sensing angle. I read that this sensor doesn't have a blind spot, but I want to reduce the sensing angle. I don't need it to sense 360 degrees, just between 100 to 180 degrees.
Is it possible to reduce the sensing angle of the RCWL-0516 sensor? Alternatively, can you suggest some common materials that absorb microwaves and don't affect the waves?
thank you
I created a toy gun using the sensor (something similar to laser tagging)
To limit its area I used few layers of aluminium foil
Sat here with a range of sensors and initially opted to use one of these for a garden security light. Connected to a 12 volt relay module (nothing else needed, other than a 12v supply to both). Unfortunately they are too sensitive. As I suspected, the shrubs in the garden are giving lots of false readings and it is also picking me up as I move around the conservatory 😂 I also had a problem when I tried one in the garage with the tumble drier in, for some reason it continually fired when the tumbler was on. Just desperately trying to find a real life use. Also, when using a ldr, it requires almost total darkness to operate, even holding it in my closed fist wasn’t dark enough. Back to PIR’s for me😢 Great video. Thanks.
That is absolutely true.
The problem with the PIR sensor is that you can not effectively use it in a hot environment.
Hi, great information. I want to use this sensor, with an arduino, to calculate the speed of a slot car. Do I need two of them or cna it be done with only one? What is the response time for the sensor? Ie how long between the car passing to the sensor being triggered? Thanks
If I have to do it myself, then I will probably do it using two.
You may have to do some experiments to find the response time mate.
Is there a way to know the speed of the sensed items and if it on the right or left side? If not, what sensor would do it? Thank you
The answer is no.
A PIR sensor can do that
I liked it and I would to try it what's the name of the white board ?
Breadboard
v great video brother ; please just one question : how to increase the output voltage ?? to have more than 4v ??
You can add a buck converter if you want
Connect to relay and switch larger voltage.
is it we can set the angle detection that we want?
You can block the areas you don't want by shielding them using aluminium foil.
thank you for this , please i have a question can rcwl0516 calculate the speed of object and send it to database
These RCWL-0516 sensors just detects the changes in the standing wave pattern and RF loading, ie they're motion sensors not speed sensors.
Do you know the value of the resistor that should be used for the sensor to be at least 30cm long?
No idea mate
Which type of capacitor to be used at c-tm pin for time increase?
Please suggest
I did mention it in three video
How fast can an object move to be seen by the sensor? Is it possible to measure the Speed of the Object?
I haven't tried
But I will give it a shot
does it work with a single layer of glass with a thickness of 2mm?
If there is no metal in the glass, no problem. Even doubled is no problem. But no metal.
That is correct.
In my next project, I have it behind a 3d printed plastic case.
Amazing video!
I have a question. Can this sensor through the wall or the thin piece of plank, and can you test it?
Thanks a lot for sharing.
Yes it does
Towards the end of the video I have mentioned all my test cases ..
@@CrazyCoupleDIY Oh my bad. I missed that infomation. Thanks for answering me!
Can I use this sensor for rat movement
Yes you may
Buy remember these sensors can pick-up any movement and has a 360 degree vision without a blind spot
hi, friend. I was experimenting with this sensor and came to the conclusion that it is not useful for alarms. It is very sensitive and is triggered by the slightest movement of a branch. Furthermore, it is impossible to direct the detection beam. Lightning cannot be channeled with either aluminum foil or 2 cm thick iron. Any comment from you would be very helpful. greetings.
I agree to your point
The way I limit its area of detection is by putting aluminium foil
In my rcwl 0516 detect range only 3 centimeter, can you help
Please check the input voltage.
@@CrazyCoupleDIY input battery Voltage is 13V
Why cant we use this sensor in the range of less than 5 metres
Yes you can
I recently bought a rcwl 0516 after connecting a single 5mm red led and powered it on the module is continuously turn on the led the led does not turn off PLEASE HELP
Are your connections as per the diagram shown in the video?
@@backless7824 yes 5v to vin, out to positive of led and negative of led to gnd
@@backless7824 not only one three of them are in this same condition
@@backless7824one thing i just observed if i hold the sensor in my palm both hands covering the sensor the led turns off if i open my hands the led turns on i also added a 1Mohm SMD resistor to the R-GN PADS to reduce the range
Hi mate
Just remember the sensor has 360 degree visibility with no blindspot.
Please use the serial monitor to see what the sensor is reading
only concern for health issue no one can guarantee it when its make cheap
True
Can dogs hear these?
I am not sure mate
will it make the bathroom light ON as long as there is a movement ?@@CrazyCoupleDIY
