Microwave Proximity Sensor

Features

• Detecting range: less than 120 degrees taper angle within 7 meters

• Trigger mode: repeat trigger

• Delay time: 2 seconds (the default value), by soldering capacitor in different capacities on C-TM pads to adjust it

• Active Level: high (when it detects a moving object)

• Output Interface: 3V3 (3.3 V power supply output), GND (power ground), OUT (output signal), VIN (power input), CDS (detection can be turned off during the day by soldering an external photoresistor to the ground). Only need to use GND / OUT / VIN in general applications.
