Microwave Radar Module - RCWL-0516

• Operating Voltage: 4-28V
• Operating Current: 2.8mA (typical); 3mA (max)
• Operating Frequency:~3.2GHz
• Detection Distance: 5-9m
• Transmission Power: 20mW (typical); 30mW (max.)
• Sensor Output Voltage: 3.2-3.4V
• Capacity Current of Sensor Output: 100mA
• Trigger Way: Repetitive Trigger
• Output Signal Low Level: 0V
• Output Signal High Level: 3.3V
• Operating Temperature: -20~80C

• C-TM:   Set repeat trigger time, default trigger time is 2 seconds; Increasing the capacitor capacity will lengthen the retrigger time and the actual counting trigger time may work as follows: 

• R-GN:  Detection distance adjustment, connect with resistor and detection distance will be shorter; If not connected, detection distance is 7m; If connected with a 1M ohm resistor, the detection distance is 5m.

• R-CDS:  Internal VCC parallel, with internal 1M ohm resistor. Connected to CDS pin (196 9-pin) via R-CDS; CDS connects with photoresistor, you can turn off the detection function at night

• 3V3: 3.3V regulator output for reference
• GND: Earth(-)
• Out: Signal Output (HIGH(3.3V) when motion detected), LOW(0V) at idle.
• Vin: Input Voltage, 4-28V
• CDS: Activates the control chip, at levels lower than 0.7V OUT is always low
