Sensors
INTRODUCTION Sensors are devices which are used to detect and respond to certain physical actions. They are able to respond to physical parameters like Temperature, Humidity, Touch, Radiation, Speed etc... They convert these parameters to electrical signals which can be measured through devices. It is not an independent device and is always used with other devices. Just like Humans they can sense their environment and respond quickly. They are better than humans when it comes to sensitivity and responding. Some Sensors also affect what they measures like, a thermometer at room temperature when measuring a hot substance, cools it down and gets hotter. Although they are designed to have a small or no effect on the parameters which they measure. Latest Technology Sensors are manufactured at the microscopic scales and are much sensitive than macroscopic sensor. These are called Microsensors which are manufactured using MEMS ( Micro Electromechanical...
