HC-SR501 Adjustable PIR Motion Detector

A PIR motion sensor, also known as a passive infrared sensor, is an electronic device that detects motion within its range using infrared radiation. It is commonly used in security systems to monitor the presence of intruders or for automatic lighting control. The sensor works by detecting changes in heat patterns emitted by objects in its field of view. When a person or object moves within the sensor's range, it will trigger an alarm or activate a connected device. The PIR motion sensor is highly sensitive and can detect even the slightest movement, making it an effective tool for enhancing security measures. It is a reliable and cost-effective solution for both residential and commercial applications.

This is a PIR motion sensor, which is based on infrared technology, use in automatic control products. It can be used to detect motion from pets/humans from about 6 meters. It has an adjustable delay before firing (approx 2-4 seconds), adjustable sensitivity.
