Most flood flights with PIR sensors have light sensors that turn the pir off during daylight hours as they get flooded with ir light. There are more advanced versions but they aren’t often used in flood lights.
Very important: keep detecting presence if object stopped moving in a middle of room, or if speed was zero. Detection should stop only when object has moved out of range, preferrably only in a configurable place (at a door). If it was done this way, it would be the ultimate presence detector. Without this functionality it's still a motion sensor. I've messed with these radars and they still fail to detect a completely still human.
Your video is excellent and very instructive. Could this radar be used in an application that involves counting people within an environment, how many have entered, left and remain in the environment, even if there are more than three people at the same time?
If it only was roof mounted. I now use Tuya ZY-M100-24G that is mains powered (230v) that is designed as a roof mounted led spot light. I wished I had this one in the same form factor
This is very interesting. I have some questions. 1- how does it compare to PIR in sense of price? 2- what is the power consumption compared to PIR? 3- Does it have problems with wind or false alarms like PIR? 4- can it distinguish between cats and humans? 5- does it have problems if you put in inside a case?
1. they are about $5 vs 10 cents 2. a lot more power, 50-100mA, no good for batteries 3. it is not affected by wind at all. Much fewer false alarms than PIR 4. Not the hlk ones 5. It can see through many plastics. Mine have an open front.
@originalmianos thank you! For the power consumption i agree it's not good for battery powered applications. However if it has some low power modes I can make it work. There's a Rd-03L model which is low power and datasheet says it runs in uA range. However the datasheet is inconsistet about this.
Thanks for the video!! Thowing a kalman filter on here and fusing with computer vision in zero ambient light is an absolute game changer.What's the recommended way to solder this to a pcb? Just use the JST or solder some pins to the 2.54mm and go through hole? Thanks in advance :)
Thank you for the fantastic video explaining how the RD-03d works. However, I would like to know where you found the documentation that provides the command codes to configure the RD-03d in single target and multi target modes. On the manufacturer's website, you can only find the document referring to the RD-03 serial communication protocol and it does not include the commands that were used in the demonstration programs for the module's operation.
What i really need would be to track a single radar emmiter with one or more radar receiver.. Wanna try to make a custom vr controller that doesnt rely on vision
I have something similar but older. I couldn’t use it for human detection if my ceiling fans were on. Does this module still detect humans accurately if a ceiling fan is on? Great Video!
I have a couple of multi-target mmWave devices that work with HA via WiFi. I had used them to turn lights on when I'm at my desk and turn off when I leave. Two different vendors, at least one is ESP32 based. A word of caution - both started acting erratically after a few months and the sensors eventually stopped working. I think both died due to heat, which is disappointing because the ambient temperature where they're located would have maybe only hit 85F/30C. I'd be curious to know if anyone else has had this problem.
I am trying to make a Arduino project using a HLK-LD2541 radar thing, but I do not know how. Can you make video to show me. There is no library but there is library for LD 2540 maybe I can use that ????
I have some question: 1. Can it track moving object for example like a moving toy boat? the toy is made out of a can. 2. Can i put it on a stepper motor so it spin and scan everything around it
I would like to ask following: 1. Does it detect motion due to FAN or similar stuffs and malfunctions? 2. How much of resting detection can be reliable. I mean if a person is super still and working on desk then will it detect it as presence or just a normal object. 3. is the direction of detection only on the front face or anyone behind can also be tracked??? Would be glad if you let me know. I want to use this for my home automation as presence detector.
@@ElectroniClinic Just to clarify if you sit down/remain still for longer than 5 minutes or so it still detects your presece just fine? This was an issue with LD2450 which seems to drop target ~30 seconds unless I make some movement (which is why I had to go back using LD2410)
No! It is just very low power microwaves at a wavelength of 1.2 centimeters (24 GHz). UV, and X-Rays having wavelengths shorter than 125 nanometers (.000125 centimeters) are ionizing radiation.
I didn't test this on a bed but yes it can detect still humans. You can use c1001 mmWave sensor that can monitor a sleeping person. Check the playlist.
Can it differentiate between target sizes? I've considered millimeter wave but the inability to narrow the detection bandwidth without major study and complication has been a problem. While I appreciate the sensitivity whilst being able to penetrate walls/doors, etc., I have house cats that constantly trigger sensors that aren't intentionally limited in scope. If I could have a set point of 20+ kilos mass as an example, I could install one sensor per area without much consideration beyond hiding them for esthetics.
I don't think mmWave will replace most PIR sensors. Reason 1: They use more power than PIR sensors making battery-powered sensors infeasable (battery life less than 2-3 years is not enough). Reason 2: Privacy - mmWave can collect too much data. A PIR sensor is enough in hotel rooms. However, mmWave could be useful beacuse it can measure distance - eg you could use it to turn on the light at the right spots.
@ElectroniClinic you are just showing the equipment turning on and off, for better clarity and eagerness for the viewers consider showing the entire setup of the rig. And wat was the enclosure (material) you tried with
@arvindh4327 I didn't show the enclosure and materials because I have already performed materials penetration test on the 24Ghz mmWave sensor. But I will try my best to cover the remaining things in the part 2.
The detail overload is real man. I don’t need an explanation of how storing a large value works in 2 bytes with high/low bytes. Again. Trim and compact this puppy. Just can’t watch this kind of ridiculous minutia.
Please create a video about this Sir i use black ph sensor cheaper than color blue please help i use esp32 if i connected to the lcd 12c to display the data but it is not accurate please help im your subcriber my title is water quality monitoring system sir please help
I get that they probably sponsored you so you are doing your best to sell it but you don't need to have a 3:00 minute advertisement at the beginning of your video. You said the same thing over and over. That doesn't convince anybody.
Oh, is it giving horizontal AND vertical angle? Or do 2 different sensors operating side by side interfere? Just connect it with a robot arm or two servos and we will see steered paint ball guns intercepting intruders …. 🤔 🤣🤣🤣
Much better to just use camera with object detection. Granted it's a bit more expensive since you need camera + edge SOC + AI processing unit for fast inference but still very doable for around $100 with enough accuracy to not only detect all the people in the room, their positions and even their pose (ie someone raises fists in aggressive stance and they get a face full of paintballs 😂).
Why are you literally repeating the specifications over and over again? I was ready to start a drinking game with my buddy to drink every time you said “multiple targets at the same time” but I would have died from alcohol poisoning. In all seriousness, this is cool stuff in a cheap small package…but man, this video could have been 4 mins long.
This looks like a nice piece to add to Home Assistant
Just perfect for my automated turret system.
Thanks!
Such a good and methodical explanation, could not be more lucky that you posted this only 4 days ago. Great job!

This will be a great board to use for security systems, robotics and search & rescue!
Great review!
And I guess someone forgot to tell floodlight manufacturer that PIR is for indoor use only. ;)
Most flood flights with PIR sensors have light sensors that turn the pir off during daylight hours as they get flooded with ir light. There are more advanced versions but they aren’t often used in flood lights.
Great video. Thanks for putting this together.
Saves a few dollars over the UWB detection system for sure - but might as well just use that for far better results.
So cool, hopefully the documentation is better translated to english and it is put up on github.
What an interesting board!

It might be interesting to get raw data from sensors. Train a neural network on this data + GPS data from objects to be detected.
Excellent video. How well does it detect small objects such as small dogs and cats?
Он их не замечает.
tracking us have never been more easy
Would one of these mounted in the middle of a staircase allow for phased LED strip control, where the lights follow you as you walk up/down?
Nice video. What happens if there are more than 3 targets in the area? Does it follow 3, does it give an error or will it give unaccurate positioning?
Where can i get my free developer sample of this beautyful piece of technology? I want to check this awesome features out, now!

The LD2XXX family has the problems with wind, either natural or artificial. How is this on windy days or rooms with ceiling fans?

Before you soldered, you applied some kind of mask, presumably to prevent solder touching adjacent pins pr components. What is this exactly?
@@tonyclif1 that was flux. It inhances the flow of solder and removes oxides.
