Description

HC-SR501 PIR Sensor | Pyroelectric Infrared Motion Detection

Key Features

• Reliable Motion Detection: The HC-SR501 PIR sensor accurately detects movement by sensing infrared radiation changes in its environment, making it ideal for monitoring humans or animals.
• Customizable Settings: You can adjust the detection range (3 to 7 meters) and delay time (3 seconds to 5 minutes) using onboard potentiometers, allowing flexibility for different projects.
• Dual Trigger Modes for Versatility: The sensor offers repeatable (H) mode for continuous detection and non-repeatable (L) mode for single-event triggers, ensuring compatibility with a variety of applications.
• Wide Voltage Compatibility: Operating on a voltage range of 4.5V to 20V, the sensor easily integrates with different power sources and devices.
• Compact and Lightweight: Its small size and low weight make it easy to fit into portable or space-limited designs.
• Energy Efficient: This sensor consumes very little power, making it suitable for battery-operated or energy-conscious devices.
