Description
This keyestudio PIR Motion Sensor Module is a compact, highly sensitive infrared sensor designed specifically for the BBC micro:bit. It is ideal for students, educators, and hobbyists looking to build smart home projects, security alarms, or automated systems. With its simple digital output, it makes integrating motion detection into your coding projects straightforward.
Reliable motion detection
This module detects movement by sensing changes in infrared levels emitted by surrounding objects. It offers a reliable detection distance of 3 to 5 metres, making it perfect for security and automation projects.
Wide detection angles
The sensor covers a detection angle of less than 80 degrees horizontally and less than 55 degrees vertically. This directional focus helps prevent false triggers from peripheral movement.
Low power consumption
Operating at a working voltage of DC 3.0V to 3.3V and a current of 100mA, the module has a maximum power consumption of only 0.5W. This makes it highly efficient for battery-powered micro:bit applications.
Compact and lightweight design
Measuring just 31mm by 27mm by 6mm and weighing only 2g, this sensor easily fits into tight spaces and lightweight enclosures. Its small footprint ensures your custom builds remain neat and portable.
Simple digital output
The module outputs a straightforward digital signal, allowing for easy coding and integration with your BBC micro:bit. You can quickly program responses to detected motion using block-based or text-based coding.
Resilient environmental tolerance
Designed to operate in temperatures ranging from -30 degrees Celsius up to +80 degrees Celsius, this sensor is built to withstand diverse environmental conditions. It is also ROHS compliant, meeting strict environmental standards.
Comprehensive learning resources
To help you get started quickly, keyestudio provides a dedicated Wiki tutorial page. This resource guides you through the setup, wiring, and programming steps needed to bring your projects to life.
