PIR SENSOR

The PIR Motion Sensor is an electronic sensor used to detect the motion of humans or animals by sensing changes in infrared (IR) radiation emitted from warm objects. It provides a digital output signal when motion is detected and can be easily interfaced with microcontrollers such as Arduino, ESP32, STM32, Raspberry Pi, and PIC. The sensor offers low power consumption, adjustable sensitivity and detection delay, and reliable motion detection within its sensing range. Due to its simple operation and cost-effectiveness, the PIR Motion Sensor is widely used in security alarm systems, automatic lighting control, smart home automation, occupancy detection, energy-saving systems, and IoT-based motion sensing applications.
