TTVKTR open-source firmware converts old IR remote controls into presentation clickers through Raspberry Pi RP2040 USB boards ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...

Abstract: Miniaturized non-dispersive infrared (NDIR) gas sensing systems require as key components bright thermal infrared (IR) sources that can be modulated at reasonably high speed to allow ...

Atsugi, Japan — Sony Semiconductor Solutions Corporation (Sony) today announced the upcoming release of the IMX775 CMOS RGB-IR image sensor with the industry’s smallest *1 pixel size of 2.1 µm, ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

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 ...

Learning electronics? Then, chances are you already know what an Arduino is, or at the very least, you've heard of it. After all, it's among the most popular electronics platforms available in the ...

Abstract: COVID-19 and its genetic mutations pose a challenge to the world and affect the economic system of countries. Recently, countries were forced to reduce restrictions on airports, universities ...
