PIR Sensor (Part 2)
In this tutorial we will connect our HC-SR501 PIR (movement) Sensor to an Arduino UNO. The PIR sensor will be powered by the Arduino and when movement is detected, the PIR sensor will send a signal to Digital Pin 2. The Arduino will respond to this signal by illuminating the LED attached to Pin 13.
PIR Sensor (Part 1)
PIR sensors are pyroelectric or “passive” infrared sensors which can be used to detect changes in infrared radiation levels. The sensor is split in half, and any significant difference in IR levels between the two sections of the sensor will cause the signal pin to swing HIGH or LOW. Hence it can b
