The Arduino ecosystem is an amazing learning tool, but even those of us who love it admit that even the simplified C Arduino ...

I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge! The build is based around a Wemos D1 mini, a ESP8266 development board.

This letter reports, for the first time, a molybdenum-disulfide (MoS2)-coated microwave gas sensor for methanol gas detection. A wideband monopole antenna, resonating at 2.45 GHz for wireless ...

Robust gas sensing is fundamental to safety, environmental monitoring, and industrial control. However, the design of intelligent gas analysis algorithms remains constrained by a key instrumentation ...

Highly sensitive and reusable sensors for detecting harmful gas molecules are particularly important to reduce their harmful impacts on human health and the natural environment. Based on the density ...

I built an indoor air quality monitor to monitor air temperature and humidity using the DHT22 sensor. It also has an MQ-2 gas sensor to monitor LPG, smoke, and CO molecules in the air. esp8266 udp ...

There aren’t any releases here You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

Indoor air pollution poses a major global health threat, with complex chemical components and low detection standards being core issues. Due to intrinsic cross-sensitivity, a wide range of commonly ...
