welcome to the parallax perspective I'm John Williams and I'll be telling you about the PIR sensor the PIR sensor is a motion detector designed specifically for microcontroller applications it's similar to the sensor used in motion activated porch and bathroom lights it looks for changes in the infrared field and can detect human movement up to 20 feet away the PIR sensor is great for home build alarm systems and motion activated displays as always when you have questions our support team is here to help I'm John Williams and that's the parallax perspective on the PIR sensor
