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.

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

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.

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

Bosch has introduced a four-in-one mems sensor that measures air pressure, humidity and temperature, aa well as detecting volatile organic compounds, volatile sulfur compounds (indicating bacteria), ...
