Product Description
DIYmall RCWL-0516 Motion Detection Sensor, Microwave Radar Sensor, Switch Module, for Arduino ESP8266 Nodemcu Wemos, for Raspberry PI, for Human Rat Cat Detector, Detection Distance 5-7m
- 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
- It can work with (for) arduino/nodemcu/wemos etc.; It can detect human, cat, rat, water
- What you will get: 5pcs RCWL-0516 Module, 5pcs 4P bend pin header
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 5m
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 Included:
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: It works with ESP8266 well.
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.
Q: Can it be mounted mobile to detect persons?
A: No. The sensor seems to be quite sensible to movement itself. Any movement of the sensor itself seems to trigger the output
