Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I ... 9540/arduino-fan-speed-controlled-temperature/ ...

Most already come complete with the UNO board and a bunch of components like LEDs, a temperature sensor, a DC motor, a servo motor, and an LCD module. Then, there's the matter of the power supply.

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. Head over to ...
