The MH-SR602 is a compact, low-power PIR (Passive Infrared) motion sensor module specifically designed for embedded systems, Arduino projects, and battery-powered applications. It detects human motion by sensing infrared radiation emitted by the body, making it ideal for security systems, automation, and energy-saving solutions. With a simplified interface and minimal power draw, the MH-SR602 is well-suited for motion-triggered operations such as lighting, alarms, and display activation. It features an adjustable delay time and a digital high/low output signal when motion is detected.
• Miniature size ideal for compact projects and wearable devices
