HS0741 RCWL-0516 Microwave Radar Sensor

HS0741 RCWL-0516 Microwave Radar Sensor

   

Product Introduction:

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.Module and installation carrier
