Description
The HKD Digital Mini PIR Motion Sensor (HC-SR505) is a compact and energy-efficient passive infrared (PIR) motion detection module designed for automatic sensing applications. Using infrared technology, it detects changes in heat emitted by people or animals and converts this information into a digital output signal.
Thanks to its ultra-small size and low power consumption, the HC-SR505 is especially well suited for battery-powered devices and space-constrained designs. The sensor features automatic control with a repeatable trigger mode, allowing it to continuously detect motion without requiring a reset between triggers.
When motion is detected within its sensing range, the module outputs a high-level digital signal, making it easy to interface with microcontrollers, relay modules, alarms, or lighting circuits. Its wide operating voltage range and high reliability make it a popular choice for both hobbyist and industrial applications.
This mini PIR sensor is commonly used in motion-activated lighting, security systems, toys, and automated electronic equipment, offering dependable performance in a simple, ready-to-use package.
