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 ...

A research team develops a real-time humidity sensing optical sensor. The response time of the new sensor is 10,000 times faster than the conventional sensors and can be mass-produced at low cost. The ...

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 ...

(Nanowerk Spotlight) Each exhaled breath carries distinct signatures of human activity - quick and shallow during exercise, deep and regular in sleep, irregular while speaking. These breathing ...

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) ...

Have the new HomePod 2 or HomePod mini smart speakers? If so, you’ve got access to built-in temp and humidity sensors with software 16.3 which can be useful in a variety of ways. Here’s how to set up ...

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 ...
