The PIR motion sensor consists of 3 pins-VCC, GND, and the Data Output Pin. VCC is the power pin of the module. Out is the data Output pin of the module.it goes high when motion is detected. GND is ...

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

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

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 ...

During the relatively brief history of electronic motion control systems, a number of communications and networking schemes have been introduced. Not all get equal acceptance in the marketplace, but ...
