Assignment: Designing a simple Electronic Circuit (Without Micro controller) to switch on /Off water pump(Motor) by checking the level of water in the overhead tank / Bottom Sump and also display the level of Water in the overhead tank
1. Simple circuit that switches on /Off water pump(Motor) by checking the level of water in the overhead tank / Bottom Sump and also display the level of Water in the overhead tank.
The circuit should able to measure the levels of water in a tank and pump motor can automatically switch on and fill the water in overhead tank and switch off once it is filled.
For example,
• Whenever overhead tank becomes empty water pump motor will run automatically by checking the water in the sump. (If it is empty Pump motor will not run)
• Water pump Motor will run until the tank becomes full (Or sump becomes empty)
• The above process will repeat till its setting changed for different levels
2. Four level LED indicator will display on the panel indicating the level/ Liters in the water tank For example,
Tank full/1000 Ltrs, Tank empty /10 Ltrs, half full /500 Ltrs,
