PIR Sensor-

The HC-SR501 PIR Sensor is a Passive Infrared (PIR) motion sensor module commonly used in electronic projects for detecting human or animal movement within its range. It’s widely employed in applications like security systems, automatic lighting, and other projects that require motion detection.

PIR Sensor Module (Passive Infra-Red ) Sensor is an electronic semiconductor-type sensor that measures infrared (IR) light radiating from objects in its field of view. This module detects and gives a trigger when there is any motion by a heat-radiating object in its range of view. This sensor is passive as it does not emit or radiate any energy for detection.

Every object above absolute zero emits heat, this heat signature is in Infrared wavelength which cannot be seen by the naked eye but can be measured by infrared devices. This Sensor is covered with Fresnel Lenses, which create a wide angle of detection and are also used for noise filtering.

This PIR includes an adjustable delay before firing (approx 0.5 – 200 seconds) and has adjustable sensitivity. It runs on 4.5V-20V power (or 3V by bypassing the regulator with a bit of soldering) and has a digital signal output (3.3V) high, 0V low. Its sensing range is up to 7 meters in a 100-degree cone.

The HC-SR501 sensor works on the principle of detecting changes in infrared radiation emitted by warm-blooded creatures (such as humans or animals) in its field of view. It has a specified motion sensing range, typically up to a few meters, and an adjustable detection angle, allowing it to cover a specific area.

The sensor provides a digital output signal (HIGH or LOW) indicating the presence or absence of motion within its detection range. When motion is detected, the output goes HIGH; otherwise, it remains LOW. The HC-SR501 module often includes adjustable potentiometers for setting the time delay (how long the output stays HIGH after motion is detected) and sensitivity (the range and sensitivity of motion detection).

The module typically operates on a low voltage supply, usually around 5V-20V, making it compatible with a wide range of microcontrollers and digital systems. HC-SR501 PIR Sensors are widely used in projects involving motion-activated lighting, security systems, occupancy detection for energy-saving purposes, and more.
