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 hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...

A research team led by Prof. MENG Gang, from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS) used polydimethylsiloxane (PDMS) in the research of high-performance ...

If you want to add humidity and temperature sensors to your home automation sensor, you can — like [Maker’s Fun Duck] did — buy some generic ones for about a buck. For a dollar, you get a little ...

Find the right lab humidifier for your facility’s compliance, precision, and control needs with this complete technology guide..

A face mask with a nanomaterial-based humidity sensor and AI model interprets breath patterns during silent speech to restore communication for patients. (Nanowerk Spotlight) Losing the ability to ...

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) ...

Hygrometers are practical gadgets for the home that can indirectly prevent mold growth. They provide an instant reading of humidity levels and indicate when it’s time to ventilate. A recent test ...

Here's how to take advantage of the temperature and humidity sensors in HomePod 2 and HomePod mini. Photo: Ed Hardy/Cult of Mac HomePod 2 and (surprise!) HomePod mini both include temperature and ...
