Bluetooth Controlled Water Level Controller

Updated: Dec 24, 2021


Water is one of the essential need for the survival of all human beings, animals and plants. The water overflow from the overhead tanks in the houses, commercial properties, educational institutions the percentage of water overflow wastage. To avoid such Spillage implementation of an automatic water level controller becomes a key factor which further reduces human intervention. In this Project work, an automatic water level controller using bluetooth wireless technology and Ultrasonic water level sensor is proposed.


This project can be further enhanced to control and animated the water level as follows.

Soft Slider - Automatic ON/OFF Pump

The water Pump automatic turning it ON, when the water level is reached LOW level set point, and water Pump automatic turning it OFF when the water level reached is HIGH level set point. The Low & High set point to be adjusted from 0 % to 100 % using slider from android app and value send to arduino and stored in Arduino EEPROM by pressing SET button in the android application.


Pushbutton- Tank height Set

A push button switch is provided for tank height set and value stored in Arduino EEPROM. If tank is empty then press to push button switch for tank height set in cm and value send to arduino and stored in EEPROM.
