The PIR (Passive Infrared) Motion Detector Sensor Module HC-SR501 is a widely used sensor module for detecting motion in its surrounding environment. It is commonly used in security systems, automation projects, and various interactive installations.
Key features include:
Passive Infrared Technology: The sensor module detects motion by measuring changes in infrared radiation emitted by objects within its detection range.
Sensing Range: Adjustable sensing range typically up to 7 meters (approximately 23 feet), with a detection angle of about 120 degrees.
Sensitivity and Delay Adjustment: The module usually features potentiometers or jumpers for adjusting sensitivity and delay time after motion is detected.
Trigger Modes: Configurable trigger modes include single trigger and repeatable trigger modes, allowing flexibility in various applications.
Operating Voltage: Typically operates at 5 volts DC, making it compatible with most microcontroller platforms like Arduino, Raspberry Pi, and others.
Output Signal: Provides a digital output signal (usually HIGH or LOW) when motion is detected, which can be easily interfaced with microcontrollers or other devices.
Low Power Consumption: Consumes minimal power in standby mode, making it suitable for battery-powered applications.
Compact Size: Small form factor for easy integration into various projects.
The HC-SR501 PIR Motion Detector Sensor Module offers a simple and effective solution for motion detection applications, providing reliable performance and ease of use. Whether you're building a motion-activated light, a security alarm system, or an interactive art installation, this sensor module can enhance the functionality of your project by adding motion-sensing capabilities.
