Tired of condensation wrecking your shed tools or greenhouse gear? I built a no-frills ESP32 + DHT22 node that wakes every 15 minutes, grabs temp/humidity data, beams it over Wi-Fi, and sleeps—running ...

The Hygrotron humidity and temperature sensor from Hygrometrix Inc., Alpine, Calif. (hygrometrix.com), is smaller than a dime but can determine relative humidity (RH) between 0 and 100% with 1.5% ...

Honeywell introduced the new HumidIcon(tm) Digital Humidity/Temperature Sensors, HIH-6130/6131 Series, offering industry- leading accuracy, stability, and energy efficiency in a lowest total cost ...

Researchers present paper-based temperature and humidity sensors that are accurate, reliable, and eco-friendly. The team created the sensors by printing silver lines on commercially available paper ...

Researchers developed a fingertip-sized, humidity-tolerant hydrogen sensor using platinum nanoparticles that catalyze reactions, thin a water film, change color, and trigger alarms. (Nanowerk News) ...

Now this is proof that smart home tech doesn’t have to be expensive ...

Hydrogen plays an important role in society’s energy transition. For the technology to be used on a broad scale, effective hydrogen sensors are required to prevent the formation of flammable ...

Wherever hydrogen is present, safety sensors are required to detect leaks and prevent the formation of flammable oxyhydrogen gas when hydrogen is mixed with air. It is therefore a challenge that today ...
