Radar/doppler motion sensor

RCWL-0516 Microwave Radar Sensor Switch Module Body Induction Module 4-28V 100mA

Description

• Operating Voltage: 4-28V
• Operating Current: 2.8mA (typical); 3mA (max)
• 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

Instructions

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

Notes

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
