The SmartElex LHI778 PIR Motion Sensor is a compact, low-power, and reliable sensor designed to detect motion using infrared (IR) technology. It works by sensing changes in infrared radiation emitted by nearby objects, especially human bodies. When movement is detected within its 120° field of view, it outputs a HIGH signal, making it perfect for security systems, lighting automation, and presence detection projects. The sensor offers adjustable detection distance (up to 6m) and response time (0.3s–25s) using onboard potentiometers. With a low current draw and wide voltage support (3V–5V), it’s ideal for both battery-powered and embedded systems.
Features:
- Wide operating voltage: 3V to 5V
- Adjustable detection range: Up to 6 meters
- Customizable response time: 0.3 to 25 seconds
- Low current consumption: 100–150µA
- Large detection angle: 120° field of view
- Compact and easy to integrate in small enclosures
- Infrared wavelength detection: 7–14μm
- Ideal for motion-activated systems and smart automation
