PIR Sensor (HC-SR501)

The HC-SR501 PIR Motion Sensor is a reliable, low-cost module designed for heat-based motion detection. Using infrared technology, it senses the movement of people or pets within a 7-meter range. It’s the perfect choice for automated lighting, security systems, and energy-saving projects that require hands-free triggering. Key Features: Wide Detection Range: Adjustable sensing distance from 3 to 7 meters with a 120° detection angle. Dual Control Knobs: Built-in potentiometers to manually adjust sensitivity and time delay (5s to 300s). Trigger Modes: Supports repeatable and non-repeatable triggers for versatile automation logic. Low Power Consumption: Operates efficiently on 5V–20V, making it ideal for battery-powered security devices.
