Embedded Systems
INTRODUCTION
1.1 What is Embedded Systems?
Consider some real-world examples. Firstly, the case of an Intelligent Water-Level Controller For this, some sensors (MEMS based) is placed in the water tank, for level detection. The electrical outputs of the sensor are handled by an embedded login circuit. This circuit takes its own decisions for controlling the water pump. If the water level decreases from a certain level, the login circuit automatically turns-on the pump. In the same manner, if the logic circuit automatically turns-on the pump. In the same manner, if the water level increases from a certain level, it automatically turns-off the pump. Digital Soldering Station is another case, in which an embedded logic circuit controls the header for providing a constant temperature at the tip, by constantly detecting the tip temperature. In contrast to a manual gear system, an automatic gear system automatically changes gear levels according to vehicles’ speed conditions. A smart TV automatically adjusts picture quality according to ambient brightness conditions, through a photo sensor and an embedded circuit.
From above discussion we can conclude that, Embedded Systems are small systems embedded or hidden within a large system like TV Receiver. These small systems take big decisions also.
