About this item

The ELECROW Crowtail‑PIR Motion Sensor 2.0 is a compact and energy-efficient module designed to detect human motion using passive infrared (PIR) technology. It is ideal for applications such as security systems, automated lighting, and presence detection in IoT projects. This sensor operates within a voltage range of 3.0V to 5.5V and features a detection angle of 120°, with a maximum range of 6 meters. The detection range can be adjusted via an onboard potentiometer, allowing customization based on specific requirements. The module outputs a digital signal: a HIGH (VCC) when motion is detected and LOW (0V) when no motion is detected. The sensor is compatible with the Crowtail interface, making it easy to integrate with various development boards like Arduino, Raspberry Pi, and ESP32. Its compact size and low power consumption make it suitable for battery-powered applications and space-constrained projects.
