A water level controller using the 8051 microcontroller is showcased in this project. While many water level controller projects have been featured on this website, this is the first one that incorporates a microcontroller. The controller effectively monitors the overhead tank’s water level, automatically activating the water pump when the level falls below a preset threshold. Utilizing 5 LED indicators, the tank level is visually displayed, and the pump is deactivated once the tank is full. Additionally, the pump is prevented from starting if the sump tank’s water level is low, and it is turned off when the sump tank level drops during a pumping cycle.

This kit employs 4 float switches for precise water level measurement and features an LCD module to indicate both the tank’s water level and the motor’s status. With its intelligent monitoring system, the controller automatically activates the motor when the tank is empty and switches it off once the overhead tank or container reaches full capacity.
