Passive Infrared Sensor — ESPHome

Passive Infrared Sensor¶. Passive Infrared Sensors (or PIR sensors for short) are completely supported by ESPHome. These sensors measure the infrared light emitted from objects in its field of view, and if it detects a sudden change between different parts of the sensing area, the signal is pulled high.


PIR Motion Sensor: How to Use PIRs w/ Arduino Raspberry ...

HOW PIR SENSOR WORK Arduino Project Hub

The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens used here is not really doing much and so we see that the two slots can ''see'' out past some distance (basically the sensitivity of the sensor). When the sensor is idle, both slots detect the same amount of IR, the ambient amount ...
