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.

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR ...

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a ...

ICP DAS USA releases PIR-130-DC, a 1-channel passive infrared (PIR) sensor module that detects human-body generated infrared waves within a range of approximately 8 meters (315 inches) in diameter ...

You can use mmWave sensors to monitor presence rather than simply detecting motion.

Motion detection has become an essential ingredient in traditional electronic security and now it is being utilized in access control and video surveillance systems. With more applications and so many ...

Motion sensing is the detection of the change in position of an object relative to its surroundings or vice versa. There are many kinds of motion detector methods: infrared, optics, radio frequency, ...

Home automation with high usefulness and low annoyance tends to rely on reliable person sensing, and [francescopace]’s ESPectre shows one way to do that cheaply and easily by leveraging hardware ...
