Stemedu 5PCS RCWL-0516 Motion Detection Sensor, Microwave

Stemedu 5PCS RCWL-0516 Motion Detection Sensor, Microwave Radar Sensor Switch Module for Arduino ESP8266 Nodemcu Wemos for Animals Detector, Detection Distance 5-7m, Better Than HC-SR501
- 🚩 This RCWL-0516 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.
- 🚩 The RCWL-0516 microwave radar sensor module can detect inert object at the condition that it has enough density, volume and it is in motion.
- 🚩 Microwave radar sensor will sense motion through most anything. The more shielding there is, the less detection range you get. I can detect motion through glass, drywall walls, ceilings and floors. It is very sensitive. You might have to filter the power supply.
- 🚩 This microwave detector board can not only detect human but animals and water.
- 🚩 Microwave doppler radar sensor can work with arduino/nodemcu/wemos etc.
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.
