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 ...

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

Abstract: This paper introduces a new approach to design a vehicle detection module using a microwave motion sensor in order to obtain vehicle length and vehicle speed. The design of this module aims ...

Abstract: This letter presents an efficient sensor design based on a coupled microstrip transmission line integrated with a quarter-wavelength suspended open-ended stub for material characterization.

[hclxing] eagerly picked up an LED ceiling light for its ability to be turned on and off remotely, but it turns out that the lamp has quite a few other features. These include adjustable brightness, ...
