Microwave Radar Induction Switch Human Motion Sensor Module
Using Doppler radar technology£¬ this is a microwave sensor module specifically for detecting moving objects and human body. The module has many advantages such as high sensitivity£¬ long sensing distance£¬ wide sensing angle£¬ high reliability£¬ wide range of operating voltage. Widely used in human body sensing lighting system£¬ anti-theft alarm system. Features: - Working voltage: 4-28VDC - Operating current: <= 3 mA - Output voltage: 3.3V (from 3V3 pin) - Output Current: 100mA maximum - 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 (3.3V 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 ground). Only need to use GND / OUT / VIN in general applications. - Application: Automatic lighting£¬ smart home£¬ DIY projects
