RCWL-0516-RCWL-9196 Doppler Radar Microwave Sensor

These sensors operate using Doppler radar technology to detect moving objects.

Features:

• Uses RCWL-9196 chip
• The antenna is a trace on the PCB
• High-level signal output when detecting the motion with an active repeat trigger
• High-speed NPN transistor Q1
• 360 degrees no blind angle detection with a 5-7m detecting distance
• Detection is not affected by the surroundings, and it has better performance than the IR sensor
• Support night detecting function turn on /off, adjustable repeat trigger time and detecting distance by adding the SMD c
• components to the corresponding pins

Specifications:

• Working voltage: 4 – 28 VDC
• Operating current: less than 3mA (max)
• Output voltage: 3.3V
• Output current: 100mA maximum
• Operating frequency: 3.2GHz
• Transmission power: 30mW (max.)
• Detection range: less than 120 degrees taper angle within 5-7 meters
• Trigger mode: repeat trigger
• Delay time: 2 seconds
• Active level: high (when motion is detected)
• Board Size: 35.9 x 17.3mm
• Output interface: 3V3 (3.3V power supply output), GND (ground), OUT (output signal), VIN (power in), CDS (detection can be turned off during the day by soldering an external photoresistor to ground)
