The Grove - Mini PIR Motion Sensor is a compact and efficient motion detection module designed for use in various automation and security projects. It utilizes Passive Infrared (PIR) technology to detect human motion by sensing changes in infrared radiation levels emitted by the human body. The sensor is highly sensitive and can detect motion within a specific range, typically up to a few meters. It features a low power consumption design, making it ideal for battery-powered applications. With its easy integration into the Grove system, it can be quickly connected to microcontrollers like Arduino for building motion-triggered systems such as lights, alarms, or smart home automation projects.
