The RCWL-0516 is a Doppler radar microwave motion sensor. Based on the Doppler effect, Doppler radar works by bouncing a microwave signal off a desired target and analyzing how the object’s motion has altered the frequency of the returned signal. It has a sensitivity range of seven meters.
The microwave sensor has several advantage over other detection methods. It can detect moving objects behind thin walls and behind other materials such as wood. It can work from inside a case, meaning it can be stored in a waterproof case and remain safe and dry. Other advantages are that readings not affected by temperature, day, night, humidity, noise, air, dust or light, making it suitable for harsh environments.
So, what can the RCWL-0516 be used for? It can be used to detect animals or humans entering a room or open space, or activate a robot when it detects a user.
FEATURES

ADJUSTMENT PART INTRODUCTION:
- 1.C-TM Adjust repeat trigger time,default trigger time is 2s;increasing capacitor’s capacity will make repeat trigger time longer;and actual counting trigger time can operate as below: Stick capacitor on C-TM,test 9196 3-pin frequency F,repeat trigger time T=(1/f)*32768
- 2.R-GN Detection distance adjustment;connect with resistor and detection distance will become shorter;if not connect,detection distance is 7m;if connect with 1M ohm resistor,detection distance is 5m
- 3.R-CDS Internal VCC parallel connect with internal 1M ohm resistor to CDS pin (that is 196 9-pin) by R-CDS ,CDS connects with photoresistor,you can close detection function at night
