Description
Pyroelectricity Infrared Sensor is a kind of sensor that can convert the infrared ray signal emitted by a human or animal into an electrical signal. And HC-SR501 is an automatic control module based on infrared technology which has high sensitivity and security and works under the extra-low voltage mode.
The HC-SR501 Infrared Sensor Module is a popular motion detection sensor widely used in security systems, automation, and smart home projects. It uses passive infrared (PIR) technology to detect human motion by sensing changes in infrared radiation. As a result, it offers reliable performance and energy-efficient operation.
This module is highly versatile. The HC-SR501 Infrared Sensor Module features adjustable sensitivity and time delay, allowing developers to fine-tune detection range and response duration. Consequently, it works well in various applications, from automatic lighting systems to security alarms. Its wide detection angle ensures accurate motion sensing within a room or designated area.
Installation is simple and convenient. The module outputs a digital signal when motion is detected, which can be connected directly to microcontrollers such as Arduino, Raspberry Pi, or ESP32. Moreover, its low power consumption makes it suitable for battery-operated systems and energy-saving devices.
Durability and reliability are key advantages of the HC-SR501 Infrared Sensor Module. It is housed in a compact plastic casing that protects the internal sensor while maintaining sensitivity. Additionally, the module can function in both indoor and sheltered outdoor environments, ensuring consistent performance.
Features
- Fully automatic induction: With detected creatures being within the detection range, the high level is output; if not, a delay is executed automatically and high-level output will turn to be low-level output.Â
- Micro power consumption: Static Current < 50uA, especially suitable for automatic control products powered by the dry battery.Â
- Output high-level signal: Applies to various kinds of circuits.Â
- Working Voltage: DC 3.6V to 30V;Â
