Automatic Signal and Alarming System To Avoid Engine Overheating
Modern technology is largely depends on automation and control system. Automation and control system refers the use of various control systems for operating equipment such as machinery, processes in factories, boilers and heat treating ovens, switching on telephone networks, steering and stabilization of ships, aircraft, automobile and other applications with minimal or reduced human intervention. The greatest advantage of automation and control system is that it saves labor. However, it is also used to save energy and materials and to improve quality, accuracy and precision. Because of these advantages, nowadays automation and control system is using in every sector. Automobile sector is not out of it. The aim of this project is to design and to develop such type of automatic control system for an engine which will aid in protecting the engine from over heating by means of alarm and signal through a temperature sensor. This signal and alarming system mainly consists of temperature sensor circuit, micro controller and LCD. The temperature sensor is fixed to the engine, and operating temperature is measured by this. This produces the alarm and signal when the engine temperature exceeds the set temperature limit. LCD continuously shows the operating temperature of engine.
