마이크로웨이브 레이더 모션 센서 -RCWL-0516

(Microwave Radar Motion Sensor -RCWL-0516)

개요

본 제품은 마이크로웨이브 레이더 모션 센서입니다.
사람 신체 검출하는 induction switch 모듈입니다.
5-7m 가량의 움직임을 검출 할수 있는 센서로 PIR 모션센서와 비교하여 좀더 관통력을 가진 센서입니다.

특징

1.Operating Voltage:4-28V
2.Operating Current:2.8mA (typical);3mA (max)
3.Detection Distance:5-9m
4.Transmitting Power:20mW (typical);30mW (max)
5.Output Voltage:3.2-3.4V
6.Output Voltage Driving Capacity:100mA
7.Trigger Way:repeat trigger
8.Output Control Low Level:0V
9.Output Control High Level:3.3V
10.Operating Temperature:-20~80 celsius
11.Storage Temperature:-40~100 celsius
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

Pin Definition:
1.3V3:3V3 power output
2.GND:ground
3.OUT:control output;when detect moving objects,it will output high level
4.VIN:input voltage,4-28V
5.CDS:enable control chip,lower than 0.7V,OUT will output low level all the time

Notice:
1.The right ahead of induction side should't place any metal to block
2.The front/back side should reserve more than 1cm space
3.the module carrier plane and install as flat line
4, a certain application of effective detection area
5, the component side of the module is positive sensing face, the opposite is negative sensing surface. Negative sensing surface sensing less effective
6, microwave modules can not be large-scale applications in the same area, otherwise there will be mutual interference. Between single individuals over distance greater than 1M
