Pir Triggered Controller Relay


-->

Pir Triggered Controller Relay. The relay modules has only one three pin ic, which should be the pnp transistor. Combined with a pir sensor, a couple of transistors and a relay board, you can easily turn on a relay when motion is detected and have it turn off after a certain amount of time, set by the values of r1 and c1.
