AUTOMATIC WATER LEVEL MONITORING SYSTEM
In most houses, water is pumped up to the overhead tank located on the roof from the ground. People generally switch on the pump when their taps go dry and switch off the pump when the overhead tank starts overflowing. This results in the unnecessary wastage and sometimes non-availability of water in the case of emergency.
Automatic Water Level Monitoring System presented here makes this system automatic, i.e. it switches on the pump when the water level in the overhead tank goes low and switches it off as soon as the water level reaches a pre-determined level.
This project is an 8051 microcontroller based in which microcontroller is interfaced with an LCD to display the water level in the tank and the status of motor. Transistors are used to determine the water level in the tank. The circuit is based on 3 transistor switches. Each transistor is switched on, when its base is supplied with current through the water through the electrode probes. The microcontroller programmed by using KEIL C cross Compiler.
We can implement this project at house hold level, industrial level etc For example; we can implement this project in reservoirs.
