The aim of the project is to make a low voltage and high voltage indicator.The system will save costly electrical and electronic appliances from the adverse effects of very high and very low mains voltages.A project has been proposed on simulating a overvoltage and under-voltage protector, with the hardware.The advantages of our project are -Wide single supply voltage range 2.0 V DC to 36 V DC ,Very low supply current drain (0.8mA) independent of supply voltage , low input biasing current 25mA.,Inputcommon mode voltage range includes ground, differential input voltage range equal to the power supply voltage.
