We can connect this LDR in a voltage divider (along with other resistor) and check the voltage drop across the LDR. When the light falling on an LDR is more, its resistance becomes very less and when the light is less, well, the resistance of the LDR becomes very high. It is a device, whose resistance varies according to intensity of light it is subjected to. The simplest example of a sensor is an LDR or a Light Dependent Resistor. The definition of the Sensor can be better understood if we take an example in to consideration. The term вЂњinput deviceвЂќ in the definition of a Sensor means that it is part of a bigger system which provides input to a main control system (like a Processor or a Microcontroller).ДЄnother unique definition of a Sensor is as follows: It is a device that converts signals from one energy domain to electrical domain. There are numerous definitions as to what a sensor is but I would like to define a Sensor as an input device which provides an output (signal) with respect to a specific physical quantity (input). In fact, there are hundreds of individual control systems which preform unique tasks for a safe and smoot journey.Д«ut in this tutorial, we will be concentrating on the Sensors part of a system and look at different concepts associated with Sensors (like types, characteristics, classification etc.). This is an extremely simplified version of Flight Control System. The combination of Sensors, Computers and Mechanics makes it possible to run the plane in Autopilot Mode.ДЄll the parameters i.e., the Sensors (which give inputs to the Computers), the Computers (the brains of the system) and the mechanics (the outputs of the system like engines and motors) are equally important in building a successful automated system. The computer then provides control signals to different parts like engines, flaps, rudders, motors etc. A Computer takes data from all these sensors and processes them by comparing them with pre-designed values. Almost all civilian and military aircrafts have the feature of Automatic Flight Control system or sometimes called as Autopilot.ДЄn Automatic Flight Control System consists of several sensors for various tasks like speed control, height monitoring, position tracking, status of doors, obstacle detection, fuel level, maneuvering and many more. The example we are talking about here is the Autopilot System in aircrafts.
