PIRセンサーREV B.

PIR Motion Sensor |

A PIR Sensor can tell when something nearby moves. The sensor detects the pattern of infrared energy in its surroundings. If the pattern changes, the sensor outputs a high signal. The Propeller microcontroller only needs to monitor this signal with an I/O pin to know if something is moving around nearby. Circuit Parts (1) PIR Sensor Rev B (#555 ...

The input will be held high by the R until the PIR switches to Gnd. You can also use internal pull up resistors (use the search box at top of page). Weedpharma
