Abstract : Each and every part of our life is somehow linked with the embedded products. Embedded systems are the product of hardware and software co-design.

Embedded system is becoming an integral part of Engineering design process for efficient analysis and effective operation.

From data analysis to hardware work, everywhere embedded products are the main interest because of its reliability and time bound perfection.

Due to time complexity in electronic aspects embedded systems have become a major part of our daily life. This project describes the design of an embedded system for the MCROCONTROLLER BASED DAM CONTROL SYSTEM.

Personal Computer based electrical appliances control is an interesting Personal Computer based project, mainly useful for industrial applications, home automation, and supervisory control applications.

This project gives exact concept of interfacing a high voltage electrical device or DC / AC motor to high sensitive personal computer system.

We are using RS232 as the communication medium between personal computer and controller. We are controlling the dc motor by sending signals from the personal computer to controller.

This project uses regulated 5V, 500mA power supply, LM7805 three terminal voltage regulators for voltage regulation. Full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.

Water level in a dam needs to be maintained effectively to avoid complications. This is generally performed manually which requires full time supervision by the operators & have fairly large staff complements.

Moreover, the quantity of water released is hardly ever correct resulting in wastage of water & it is impossible for a man to precisely control the gates without the knowledge of exact water level and water inflow rate.

The main objective of this project is to develop a mechatronics based system, which will detect the level of water and thereby the movement of gates can be controlled in a real-time basis which offers more flexibility.

This system consists of a set of sensors connected to a stepper motor through an 8-bit microcontroller (AT89S52). The water level is detected based on the feedback from the mechanism used.

Based on this data, the level of dam gate can be controlled using a stepper motor via personal computer.
