Simple USB powered PIR sensor with LED attached to it (no arduino)
I have purchased a PIR sensor from ebay. On a breadboard, I connected the sensor to a single LED and I saw that the voltage was low (1.75V circa). … Also, the PIR sensor model I'm using is HC-SR501 (Ebay PIR Sensor HC-SR501)

Simple USB powered PIR sensor with LED attached to it (no arduino)

Thanks! …
