The HC-SR501 is a PIR motion detector with an adjustable range that can sense up to 7m. The sensor uses infrared technology and features high sensitivity, ultra-low voltage mode, high reliability, and is ideal for use in battery-operated equipment.
This sensor is designed for use in security products, alarm systems, lighting control, industrial automation, toys, etc.
HC-SR501 auto-senses light is used for various applications (in house, basement, outdoor, warehouse, garage, etc,) for ventilator control, alarm, etc.
PIR sensor is specially designed to detect such levels of infrared radiation.
It basically consists of two main parts: A Pyroelectric Sensor and A special lens called Fresnel lens which focuses the infrared signals onto the pyroelectric sensor.

• Adjust the distance potentiometer clockwise rotation, increased sensing distance (about 7 meters), on the contrary, the sensing distance decreases (about 3 meters).
• Adjust the delay potentiometer clockwise rotation sensor the delay lengthened (300S), on the contrary, shortens the induction delay (5S).

Application: Automatically sensing light for Floor, bathroom, basement, porch, warehouse, Garage, etc, ventilator, alarm, etc.
