Build a tiny ESP32 OLED keychain with a 1.3-inch display and custom 3D-printed enclosure. Wire the ESP32 S3 and program it ...

I don’t recommend bypassing an oxygen sensor. Upstream sensors help control the air-fuel mixture, while downstream sensors often monitor the catalytic converter. A bypass can hide an emissions fault ...

All [Hannah Robertson]’s Birduino needs is for one to tap an NFC-enabled card to the reader, and the device plays one of the vocalizations associated with the bird shown on the card. It ties together ...

Multifunctional structural metals capable of monitoring their internal mechanical state are increasingly important. Here multilayer strain sensing architectures are embedded directly within Ti-6Al-4V ...

Emerging air quality sensors – with general traits of being more compact, directly reading pollutants, and lower in cost than traditional methods - have a wide appeal to professional researchers, ...

Air sensor monitors that are lower in cost, portable and generally easier to operate than regulatory-grade monitors are widely used in the United States to understand air quality conditions. This ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Sensors and Diagnostics is a gold open-access journal publishing innovative and high-impact research on sensing technologies and diagnostic systems. The journal focuses on studies that explore novel ...
