Frequently asked questions
The PIR Mini Sensor detects motion up to 3.65 meters(12 feet ) away. the other passive infrared sensors we carry, the PIR motion Mini contains a pyroelectric device that senses and responds to changes in the infrared levels emitted.
A PIR motion sensor is an electronic sensor used in motion detectors such as automatically triggered lighting devices and protection systems that measure devices emitting infrared light in their field of view.
Most PIR motion sensors are 3-pin termitar designs that produce a digital output. A sensor produces a pulse when motion is detected. which is then captured with a PIR motion sensor controller and processed.
Motion can be detected by monitoring changes in Infrared light (passive and active sensors) Visible light (video and camera systems) Radiofrequency energy (radar, microwave, and tomographic motion detection).
The PIR sensor should be powered with at least a 5V DC Line, but it can work with voltages as high as 12V. Fortunately, even if a PIR is powered higher than the 5V DC Line, the alarm pin can still connect directly to an input pin because it is designed as an open collector.
