Nano PIR movement detector  - SB312

This micro proximity/movement detector is used to detect movement near of the dome. With its conic angle of 100° (conic) each movement next to the sensor will be detected. As soon as the movement is detected, its output is set to high level (3.0V) for 2 seconds and falls to low level as soon as the movement ends.

This sensor can be powered from 2.7V to 12V, which is great to power it from a low voltage microcontroler like the Raspberry-Pi Pico (or nano computer like the Pi-Zero). What ever is the is the powering voltage, the output signal stays at 3.0V :-)

Another great feature of this sensor is its very small size of 19mm depth (without connector) x 12mm (dome diameter). As the board is already fitted with connector, so it is easy to plug it onto breadboard or wired with dupond wire.
