This article explains an upgraded smart solid-state AC switch system that uses microwave Doppler radar instead of traditional ...

Last year, I took a look at some mostly low-cost passive infrared (PIR) motion sensor modules. Then recently, I became more aware of cheap microwave radar motion sensor modules. The popular version of ...

The hype is finally turning into reality—microelectromechanical-systems (MEMS) sensors have turned into one of the hottest emerging component areas for medical, consumer, industrial, and automotive ...

It’s really hard to overstate how awesome ESP8266 development boards like the Wemos D1 Mini really are. For literally a couple of dollars you can get a decently powerful Wi-Fi enabled microcontroller ...

Some motion sensors are based on optical measurement technologies to provide accurate velocity and position measurements without requiring physical contact with the object or surface being monitored.

Building sensors with ESP32 board is quite cost-effective ...

Finding the best HomeKit motion sensor grants some new abilities to Apple's Home app, and with Thread technology, this will "Matter" even more going forward. Motion sensors can be used for more than ...

A good source of hackable home automation parts has come for a while in the form of inexpensive modules offered by large retailers such as Lidl, or IKEA. They’re readily available and easy to play ...

Key Takeaways Motion sensor lights can reduce home energy usage by 30% to 50% compared to traditional always-on lighting systems, depending on usage patterns. Sudden illumination from motion detection ...
