Industry Micro:bit Project

Water level measurement system controlled by Micro:bit

Liquid level measurement in process tanks for monitoring and/or control is essential in process industries.

In process plants, tanks hold a variety of usually expensive liquids. Some liquids are also flammable and corrosive.

Therefore, it is very important to monitor the level of liquid in a tank so that it does not overflow from the tank.

Purpose of this project:

In this project, we will build a bottle water level monitoring system controlled by the Micro:bit card.

Description of how the monitoring system works :

We know that water, like any other liquid, is a conductor of electric current.

The detection of the level of water filled in the bottle is based on this idea.

When the water level rises, this liquid comes into contact with the end of the connection wire fixed in the bottle, the electrical circuit is then closed and an electrical current under very low voltage is detected by the Micro:bit card.

When the water level drops, the electrical circuit is open. As a result, there is no more electric current.

Then the Micro:bit card displays the water level on its display.


First We drill six holes in the bottle. Then we fix a connection wire in each hole.

Then we connect the wires of the bottle to the Micro:bit card.

Makecode program

Here is the Makecode program which can detect the level of water filled in the bottle and display the water level on the display of the Micro:bit card.
