Arduino Uno: The microcontroller that will process the data from the DHT11 sensor. DHT11 Sensor: A digital sensor capable of measuring temperature in the range of 0°C to 50°C with an accuracy of ±2°C, ...

Arduino-Based Temperature and Humidity Sensor Using DHT22 This project demonstrates how to measure temperature and humidity using the DHT22 sensor and an Arduino. It provides real-time data readings ...

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 ...

You'll need an Arduino along with a bunch of various sensors to get the project rolling, and once it's all set up you'll have a simple, but cheap system to monitor your home.
