IR Sensor
An Infrared (IR) sensor is an electronic device that detects and measures infrared light emitted from objects in its vicinity. IR sensors are commonly used for proximity sensing, object detection, and distance measurement. They work by emitting an infrared light and then detecting the reflection from nearby objects. IR sensors are widely used in remote controls, motion detectors, and various automation systems due to their reliability, cost-effectiveness, and ability to function in low light conditions.
PIR Sensor
A Passive Infrared (PIR) sensor is a device used to detect motion by sensing changes in infrared radiation levels in its environment. Unlike active IR sensors, PIR sensors do not emit any infrared signals but rather detect the infrared radiation naturally emitted by objects, particularly warm bodies like humans and animals. PIR sensors are commonly used in security systems, automatic lighting controls, and energy-saving devices. They are valued for their low power consumption, wide detection range, and ability to accurately identify motion without direct contact.
