Description :

PIR Sensor (HC-SR501) Introduction Passive Infra-Red (PIR) sensors are used to detect motion based on the infrared heat in the surrounding area. This makes them a popular choice when building a system to detect potential intruders or people in general. These sensors can take for 10-60 seconds to warm up, so try to avoid motion during that time. Parts • • • Arduino PIR Sensor Wires Schematic Below is the schematic for using a PIR sensor. It is fairly simple. Code Adafruit has a really good tutorial for how these sensors are used and various projects for them. Below is the code for working with a PIR sensor. It should be noted that the PIR sensor does not respond immediately when motion stops. This has to do with the two potentiameters on the sensor.
