While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object ...

This project uses PIR (passive infrared) sensor to detect the change in radiation, this can be use on lighting control, temperature control, and motion detection since all objects with temperature ...

Like its 24-volt cousin, the 12-volt lamp is activated using a passive infrared motion sensor located in the lamp body, according to the company; the sensor is calibrated to recognize the heat ...

The passive infrared (PIR) sensor market is experiencing significant growth as demand for efficient motion detection and ...

The new Aqara Motion and Light Sensor P2 supports Thread for the first time in an Aqara motion sensor on top of Matter support for HomeKit.

Passive InfraRed sensors (PIRs) are electronic devices which are used in some security alarm systems to detect motion of an infrared emitting source, usually a human body.
