Your garden variety motion detector uses IR, but these days, there are fancier technologies for achieving similar goals. If so desired, you can source yourself a microwave-based presence sensor ...

[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, ...

I recently picked up a couple of microwave motion sensor radar modules. You have seen (and perhaps tried) it before. This post is about the HFS-DC06 (DC5V/5.8GHz) Microwave Radar Sensor Switch Module!

This paper introduces a novel, portable microwave sensor for rapid, non-invasive blood glucose monitoring. The design features an octagonal array of complementary split ring resonators (CSRRs) on a ...

This paper presents the first microwave-sensor-node integrated into a short-range wireless sensor network based on ZigBee technology. The node includes an analog front-end circuit, a Frequency ...
