This project operates in a condition of low water level.Water detector detects the water level and then sends signal to microcontroller unit. The microcontroller circuit sends signal to GSM modem and then GSM modem sends SMS to the person in-charge mobile phone. The mobile number of the user has been set in AT command of PIC16F877A and sends alert
