10-Pack HC-SR501 PIR Motion Sensor, Adjustable Delay

Key features

• ADJUSTABLE SENSITIVITY AND DELAY: Fine-tune your project with two onboard potentiometers. Adjust the detection delay time from 5 to 200 seconds and modify the sensing distance to match your specific application needs, giving you complete control over the module's response.
• WIDE COMPATIBILITY FOR DIY PROJECTS: Designed for seamless integration with popular microcontrollers, this PIR sensor works perfectly with platforms like Arduino and Raspberry Pi. It is an ideal choice for a wide range of electronics projects, including home automation, security systems, and interactive installations.
• HIGH-PERFORMANCE INFRARED DETECTION: Operating on a wide voltage range of DC 4.5V to 20V with a very low quiescent current of less than 50uA, this sensor provides energy-efficient, reliable motion detection. It features a sensing angle of less than 100 degrees in a cone shape for broad coverage.
• SELECTABLE TRIGGER MODES: A jumper setting allows you to easily switch between non-repeatable (L) and repeatable (H) trigger modes. In the default repeatable mode, the output remains high as long as motion is detected, making it perfect for applications like automatic lighting or continuous monitoring.
• COMPACT AND RELIABLE MODULE: The sensor module features a compact PCB measuring 32mm x 24mm with a standard 23mm diameter lens. It has a default block time of 2.5 seconds after a trigger to prevent false signals. We provide comprehensive after-sales support: complete digital documentation including user guides and technical references is available through our store customer service, and our support team is ready to assist with installation, programming, and troubleshooting to help you get started quickly.
