Fully Automated Water Supply System

              This is a project of fully automated water supply system designed with 16F887 Micro controller.

To build the process of the Washing machine we need several input& output devices. We use PIC 16f887 micro controller as central control device. First we should supply 5v dc to micro controller. We use a voltage stabilizer to do that. Weight sensor is used measure the weight of the cloths which we putted into washing machine. It gives analog input to the micro controller.

In this application we categorize the weight of the cloths. It as below,

0kg - 2kg = Low weight

2kg – 4kg = Medium weight

4kg – 6kg = High weight

According to these categorization put sufficient water into the washing machine. We use 3 Water level sensors to measure the water level. If we are high weight cloths have to wait for the three inputs from sensor 1, 2 and 3. After adding water to the washing machine we have to input time duration manually by rotating the timer knob. And also use LCD display (8 bit) to display timing process & massages. We use 8 bit LCD display because display time is very fast procedure, it changes rapidly.
