Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

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 ...

Passive infrared (PIR) sensors, on the other hand, only detect/measure infrared radiation from objects in its field of view, ... An Infrared close object sensor installed on an industrial vehicle ...

A passive infrared motion sensor is used to detect the motion of the user’s hand in front of the clock. While all kinds of clocks and clock radios are available out there, few are motion activated.

These detectors incorporate and analyse data from multiple sensors, including a long-range passive infrared (PIR) sensor, short-range PIR sensor, microwave sensor, ... detectors, the sensor gain ...

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.
