Arduino Humidity Check

Hello, in this small but interesting project we will make a humidity check with arduino that will make a beep sound when it reaches 80%.

In this project you will need: arduino uno, multi function shield and a humidity sensor.

Step 1:

The schematics of this are very simple: The function shield fits perfectly on to the arduino, but check your arduino power conector to the computer- you may need to put some electrical tape on top of it, to prevent it with interfering with the bottom pins of the function shield which may lead issues.

The sensor goes to +5, GND and analog A5.

Step 2: Code

The code is pretty simple. It has no libraries.

Step 3: Upgrading

You can upgrade your arduino with the function shield.

For example, you can make the beeper beep with diferent delay using the buttons or the risistor., or you can display multiple things on the display by using buttons.
