Senba Sensing Tech D203S PIR sensor

Product detailed description

The PIR sensor Senba Sensing Tech D203S is a dual-element pyroelectric infrared sensor designed for detecting the motion of people and objects based on changes in infrared radiation. Thanks to its compensated dual-element construction and integrated JFET transistor in a source follower configuration, it offers high sensitivity, low noise, and good resistance to interference caused by changes in ambient temperature, vibrations, or parasitic light. The sensor is commonly used in PIR modules with a Fresnel lens for security systems, automatic lighting, and consumer electronics.
