A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

A PIR (Passive Infrared) sensor is widely used for motion detection by sensing the infrared radiation naturally emitted by warm objects such as humans or animals. The sensor remains passive, meaning ...

Let's take a modular approach to sensor testing. The Sensor Evaluation Board was created to solve the hassle of repeatedly swapping sensors during development. Based on the ESP32-S3, it includes two ...

There are a lot of presence sensors using a combination of PIR and High Frequency Radar Human Presence Detectors to get a combination of quick response and low movement detection like when sleeping.
