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.

Electronics hobbyists, experimenters and constructors of microcontroller project frequently need to measure/detect voltage, current, frequency, temperature and… proximity. Most measure ...

Every industrial motion analysis failure that surfaces at integration has the same origin. The sensor captured what was in ...

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 ...
