About this item

The HC-SR501 PIR Motion Sensor Module is a versatile and cost-effective solution for detecting motion in various applications, including security systems, automatic lighting, and robotics. Operating within a voltage range of 4.5V to 20V, it offers flexibility for integration into different circuits. The module features a detection range adjustable between 3 to 7 meters and a detection angle of up to 120°, making it suitable for a wide array of environments. Equipped with onboard potentiometers, the HC-SR501 allows users to fine-tune both sensitivity and time delay settings. The sensitivity adjustment enables customization of the detection range, while the time delay potentiometer controls how long the output remains active after motion is detected, with a range from approximately 3 seconds to 5 minutes. This adjustability ensures optimal performance tailored to specific requirements. The module’s low power consumption, drawing less than 60µA in standby mode, makes it ideal for battery-operated applications. Its compatibility with platforms such as Arduino, Raspberry Pi, and other microcontrollers facilitates easy integration into various projects. Whether for home automation, security systems, or robotics, the HC-SR501 PIR Motion Sensor Module offers reliable and customizable motion detection capabilities.
