The HC-SR501 is an integrated circuit based on infrared technology, designed for automatic control. Featuring high sensitivity and high reliability, this sensor is a mechanical necessity for burglar alarms, automated corridor lighting, and energy-saving smart home devices. It functions by detecting the heat signatures of moving objects, providing a clean digital signal to your microcontroller or directly triggering a relay.

▪Fully Automatic Induction: This sensor is a mechanical necessity because it automatically outputs a "High" signal when someone enters the sensing range and switches to "Low" after a preset delay, requiring zero continuous polling from your CPU.
▪Dual Trigger Modes: Features a jumper for Repeatable (H) or Non-Repeatable (L) triggering. In repeatable mode, the delay timer restarts every time motion is detected, ensuring the lights stay on while the room is occupied.
▪Adjustable Sensitivity and Time: The two onboard potentiometers allow you to fine-tune how far the sensor "sees" and how long the output remains active, making it a mechanical necessity for customizable security zones.
▪Low-Power "Green" Technology: With a static current draw under 50µA, the HC-SR501 is optimized for long-term battery deployment in remote outdoor security nodes or portable lighting kits.
▪Standard Fresnel Lens: The white "dome" lens is engineered to focus infrared radiation onto the internal sensor, providing a consistent 100-degree field of view for maximum room coverage.
