The BBA-4000 is a solar powered wireless infrared break beam system that is simple to install and requires no wiring. The break beam sensors are powered by lithium ion batteries that are recharged ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Proximity sensors are common enough in automation projects that we hardly give them a second thought — pick something with specs that match the job and move on. But they can be fussy to get adjusted ...

Since manufacturers rely on various critical equipment, they often cannot effectively monitor each one. Major technical issues ensue if a problem goes undetected for long enough, making unplanned ...

Sensors vary widely and can monitor and detect a variety of sources, such as light, heat, motion, moisture, and pressure. Typical sensors used in smart cities can sense temperature, proximity, ...
