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 ...

Detection using today’s microwave sensors has some advantages. Unlike traditional passive infrared motion sensors, most microwave sensors can distinguish between moving and static objects, and objects ...

[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!

Microwave radar sensors gained popularity before and during World War II for object detection. Radar sensors are non-intrusive equipment that transmits electromagnetic signals and receives echoes or ...

Presence/motion sensors are one of the best ways to make automations feel more natural, but most of them run on batteries and eventually have to be swapped. That’s one of the main reasons I really ...

Window alarm sensors are an essential part of home security systems, alerting you to unauthorized entries by monitoring window openings, glass breaks and motion. Each window alarm sensor type serves a ...

Why range-sensing applications are becoming more common. What’s the difference between radar and optical sensing? Why these sensors are better than using passive-infrared (PIR) technology. Anyone ...

Microwave photonic radar merges photonic techniques with microwave signal generation, transmission and processing to overcome the bandwidth and speed limitations of purely electronic systems. By ...
