Most modern cars have tire pressure monitoring systems (TPMS), which will alert you if your tires need air. While most of the readings they give are accurate, they can still fail like any other part ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Abstract: Traditional electrical pressure sensors are prone to electromagnetic interference; however, the emergence of optical pressure sensors offers a novel means of fabricating flexible devices. A ...

Environmental temperature fluctuations can cause sensor output variations separate from measured pressure. A sensor’s thermal sensitivity dictates the severity of these output errors, with higher ...

Flexible pressure sensors applied in wearable detection often face challenges, such as low sensitivity, large device size, poor flexibility, and long response time. This study aims to design and ...

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 ...
