These Radar sensors are used for detecting, locating, tracking, and recognizing objects of various kinds at considerable distances. It operates by transmitting electromagnetic energy toward objects, commonly referred to as targets, and observing the echoes returned from them. The module has a range of up 4 meters and only requires stable 5V to be powered. The user may vary the orientation of the module to get the best coverage.

Note:-

To increase the range, sensitivity and time turn the preset clockwise, and to reduce turn it anti-clockwise.
The guaranteed sensing range is 4m, we have tested this sensor and found it working up to 20m having the right conditions.
