The PIR (Passive Infra-Red) sensor is a pyroelectric gadget that identifies movement by determining modifications in the Infrared (heat) levels discharged by surrounding objects. When motion is spotted the PIR sensing unit outputs a high signal on its output pin. This logic signal can be checked out by a controller or utilized to own an external load. Double output modes and a practical design that carries out within specified information sheet specifications are a couple of reasons over 100,000 units are in usage around the world.
- Jumper selects brief or long settings
- Straight drive a load
- Onboard leds illuminate the lens for quick visual feedback when motion is found
- 3-Pin sip header prepared for breadboard or through-hole projects
- Small size makes it simple to hide
