And guess what, you just used two different sensors to build a project that is intuitive enough to take surrounding’s temperature and ‘react’ accordingly.

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.

Now you can build your own room temperature monitor using an Arduino board. The circuit is a combination of an Arduino UNO board, LM35 temperature sensor, ...

An Arduino reads these temperature points over I2C and then a simple thresholding function is used to detect the movement of the fingers.

High quality sensor readings from a few passives and a cheap Arduino. If that’s your jam check out this excellent series when designing your next sensing project!
