Battery Bank protection circuit

When power is switched ON the microcontroller based battery bank protection message is displayed on the LCD along with a short beep from piezo buzzer. The room temperature is sensed by the LM35 and is displayed in LCD . Simultaneously the Real Time is read from RTC IC DS1307 and is displayed in LCD. When the room temperature rises above 45°C the microcontroller gives continuous alarm and also output will be cut off.
