It’s a simple enough idea, and with an Arduino and a DHT11 temperature and humidity sensor, it was pretty easy to put together. The clothes dryer used for this experiment was a self-ventilating ...

There’s an Arduino with a custom shield that interfaces the barometric pressure sensor, real-time clock chip, a digital temperature sensor, and a humidity sensor.

The system here monitors temperature, humidity, and smoke levels and alerts you if those levels reach a certain point.

The Anavi Thermometer Development board is fully compatible with the Arduino IDE, PlatformIO, and Home Assistant via the MQTT messaging protocol.

Humidity and Temperature Sensor We are continuing our list of easiest IoT projects for students with a weather monitoring system which is one of the IoT projects using Arduino.
