Description

Like the traditional PIR sensor, RCWL-0516 is a widely popular sensor that also detects movements and is used in Alarms or for security purposes. This sensor uses a “microwave Doppler radar” technique to detect moving objects within its range. It has a sensitivity range of ~7 meters and that is very useful for multiple applications. 

When triggered, its TTL-level output pin changes state from LOW which is 0V to HIGH which is 3.3 V. The changed HIGH state remains HIGH for 2 to 3s which is a proper time to trigger something. As this sensor module provides output for 3.3V, it can easily be interfaced in with many microcontrollers and even can be used without a microcontroller. It has a power supply input range from 4 to 28 V.
