Ai-Thinker Rd-03D 24GHz Radar Sensor Module

This sensor serves as a replacement for a PIR sensor and works on the basis of microwaves and the Doppler effect. Due to a difference in speed, this sensor can detect movement, this also works through almost all materials except metal.

The Rd-03D distinguishes itself from other radar sensors because in addition to movement and presence, it can also measure the position (x,y-coordinates) of moving objects. This can even be up to 3 moving objects at the same time.

Note: No cable is included, this can be ordered separately: Molex Picoblade Female to DuPont Female cable. Note, the colors of the cable do not logically correspond to those of the sensor.
