3PCS Keyestudio PIR Motion Sensor for Arduino UNO R3 IR Motion Sensor for Human Body Motion with Keyestudio Packing Box

This pack of three Keyestudio PIR motion sensors is designed to detect infrared signals from moving people or animals, making it an excellent choice for security and automation projects. Specially designed for Arduino UNO R3, these compact sensors are ideal for South African students, educators, and makers looking to integrate reliable motion detection into their builds.

Reliable infrared motion detection

This pyroelectric infrared motion sensor detects heat signatures from moving humans or animals and outputs a simple switching signal. It is designed to replace bulky, complex legacy sensors with a highly reliable, integrated digital solution.

Designed for Arduino integration

Built specifically for the Arduino ecosystem, this sensor integrates a digital pyroelectric infrared sensor and convenient connection pins. This design minimises the need for complex peripheral circuitry, making it easy to plug in and code.

Low power consumption specifications

Operating on an input voltage of 3.3V to 5V, with a maximum limit of 6V, the sensor draws an incredibly low working current of just 15uA. It features a pin limit current of 100mA and operates reliably in temperatures ranging from -20 to 85 degrees Celsius.

Wide angle detection range

With a generous 100-degree detection angle and a range of up to 7 metres, this sensor provides excellent coverage for indoor projects. It features an output delay time of approximately 2.3 to 3 seconds when triggering a high 3V signal.

Integrated output indicator LED

An onboard LED provides immediate visual feedback by turning on whenever the output signal is high. This feature simplifies troubleshooting and testing during your development process.
