Circuit and Working Fig. 2 shows the circuit diagram of the humidifier. The system is built around an Arduino Uno (MOD1), a 5V SPDT relay module, a humidity sensor (DHT22), an ultrasonic humidifier, ...

Xiaomi Mijia Smart Temperature and Humidity Sensor 3 Mini has launched for crowdfunding at $4, featuring a compact design, smart connectivity, and long battery life.

It’s a simple enough idea, and with an Arduino and a DHT11 temperature and humidity sensor, it was pretty easy to put together.

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...

Enable the HomePod 2 and HomePod Mini's built-in temperature and humidity sensors and turn the devices into indoor weather stations.

The humidity-resistant H 2 S sensor based on PDMS-coated CuCrO 2 had a low operating temperature (100 ℃), a high response (up to 151 for 5 ppm H 2 S at 50% relative humidity), high selectivity ...

This detailed guide covers how to use HomePod temperature and humidity sensors in the Home app, create automations, and more.

It’ll also feature a temperature and humidity sensor. Oddly enough, so does the existing HomePod Mini — except Apple has only just activated the feature.
