Oil and gas production and work in confined spaces exposes field personnel to a variety of toxic and explosive gases in everyday drilling, processing, transport, and municipal operations. Explosive ...

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...

A reliable indicator of the air quality in offices, classrooms, or living rooms is the CO2 content. In fresh air, the concentration of carbon dioxide is around 400 ppm. This stands for “parts per ...

Driver-monitoring systems (DMS) are becoming common in modern automobiles. Infrared (IR) cameras, utilizing an IR-LED in combination with a photo sensor, help recognize the hazardous microsleep that ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...

Omron Electronic Components has introduced a non-contact MEMS thermal sensor that it claims can detect the presence of humans in an area without the need for movement. The sensor is intended as an ...

Proximity detection adds many smart features to the devices we use.For example, when making a call with a phone held to your ear, face detection using proximity sensing can disable the touchscreen and ...
