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

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.

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.
