Generally, in every house, there is a problem with a water tank. leaking of water if we forget that we put ON the motor, So I made a project which will give info about the water level in the tank and we can control the motor(ON and OFF). We will get the msg if the tank is empty and can make it on through our mobile app using Bolt device which has an integrated wifi chip(ESP8266) it helps to connect to the Internet. And we will control the motor using the Internet.”
