Description:

Elecrow RCWL-0516 Magnetron Radar Sensor Switch Module Body Inductie Module 4-28 V 100mA Smart Elektronica Sensor .

Features

• Equipped with RCWL-9196 chip supporting 4-28V wide voltage input, high level signal output when detecting the motion with active repeat trigger
• 360 degree no blind angle detection with 5-7m deteciting distance, the detection not affected by the surroundings, better performance than the IR sensor
• Support night detecting function turn on /off, adjustable repeat trigger time and detecting distance by add the SMD components to the corresponding pins
• Working Voltage: DC 4-28V, Board Size: 35.9 X 17.3mm/1.41 X 0.68inch

• Detection Distance: 5-9m
• Transmitting Power: 20mW (typical); 30mW (max)
• Output Voltage: 3.2-3.4V
• Output Voltage Driving Capacity: 100mA
• Trigger Way: repeat trigger
• Output Control Low Level: 0V
• Output Control High Level: 3.3V
• Operating Temperature: -20~80 celsius
• 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:

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