Compatible with popular microcontrollers like Arduino and ESP8266, these modules operate on a wide voltage range (4-28V) and offer adjustable detection distance and trigger timing, making them ideal for advanced DIY security and automation projects. ## Description Description: Wide operating voltage range: 4-28V Can output 3.3V power supply Blocking time, adjustable distance Using special signal processing control chip RCWL-9196 Compared with the traditional infrared induction PIR, the penetration detection ability About pin header: CDS = No connection VIN = 5vdc (+) (9v battery also Ok) OUT = 3.3vdc signal out when triggered GND = 0vdc (-) 3V3 = No connection (in most applications) C-TM: Adjust repeat trigger time (default 2 s). Adding a capacitor will give a longer repeat trigger time. R-GN: Detection distance adjustment (default 7 m). Adding a resistor the detection distance will become shorter. If connected with a 1-MΩ resistor, detection range is about 5 m. R-CDS: By adding a resistor (in parallel with the internal 1-MΩ resistor), user can change the light detection threshold as per individual requirement. This is applicable only when a light sensor is soldered in its pads (CDS) on the front of the circuit board. A 47–100K resistor works fine with standard 5-mm LDRs Package Includes: 5 X RCWL-0516 Module Microwave Radar Sensor 5 X 4P Bend Pin Headers FAQ: Q: Can you use the RCWL-0516 with an ESP8266? Or will you get random false positive results? A: I've done a short term test with the ESP8266 on a NodeMCU board. It seems to work just fine. The ESP greater Version 12-E is shielded and is FCC certified. So it should, by definition, not interfere with other electronics. However, one viewer reported random false positive results on a long shot. Q: Is the water in the human body responsible for the detection? A: Probably. I tested it with one empty and one water filled bottle. And even with a cat. And it seems that the bigger the object the further away it can be detected. Review: Microwave sensor - This is for the microwave sensor, not the PIR. Confusing to have two separate products in one listing.... Anyway, the sensor works great. It seems to work only when at 5v, not the 3.3. At least in my experience. Just a word of warning, this thing is pretty much omnidirectional. It senses through walls and through floors. It's not entirely what I wanted, but I can't give it a bad review as it does what it's supposed to do, I just wasn't aware of it. Anyway, as an in-room motion detector it kidna sucks, as it will detect other rooms. Unless you have a Faraday cage I guess. I suppose it could be useful if you just want to know if someone is at home. In a flat, that's not so much use as it detects downstairs moving, as well as pigeons on the roof... ## Features - ▶ Feature: The module has the characteristics of high sensitivity, high induction distance, high reliability, large induction angle, wide power supply voltage range, etc. it is widely used in various kinds of human body induction lighting and alarm and so on - ▶ Works with Nodemcu Document link: https://github.com/jxmot/ESP8266-RCWL0516#rcwl0516-details - ▶ Works with Arduino Document link : https://www.hackster.io/remnis/coolest-motion-detection-sensor-ever-d2d688 - ▶ It can work with arduino/nodemcu/wemos etc.; It can detect human, cat, rat, water - ▶ How to email us?
