About this item

The SparkFun OpenPIR Sensor (SEN-13968) is an easy-to-use passive infrared (PIR) motion sensor designed to detect the presence of humans or animals by sensing infrared radiation changes within its field of view. This sensor is widely used in security systems, automatic lighting, occupancy detection, and energy-saving applications. OpenPIR features a digital output that goes HIGH when motion is detected, making it simple to interface with microcontrollers and logic systems without requiring complex signal processing. It is designed to be sensitive enough to detect motion from several meters away with a wide viewing angle, ensuring reliable presence detection in a variety of environments. The sensor includes adjustable sensitivity and timing parameters, allowing developers to customize detection distance and output timing according to their needs. It operates at a low voltage of 3.3V to 5V, making it compatible with most embedded platforms. With its small footprint and through-hole pins, the OpenPIR can be easily integrated into breadboards or custom PCBs. Ideal for hobbyists and professionals alike, the SparkFun OpenPIR Sensor offers a straightforward solution for motion sensing with reliable performance and minimal setup.
