Sensors- An input device which measures a physical quantity (physical quantity is an amount of something) that is constantly changing (in enables a computer top know its surroundings). e.g. Heat, speed sensors
Process- This when you input something and manipulate it etc. so it has a useful output.
Analogue-this is a real world value.e.g. a sensor
Digital- an electronic device which in codes data in the form of naught's and ones.
Measurement is the monitoring of physical variables without the microprocessor taking action.
Control is when the microprocessor takes action depending on sensor readings.
For example, starting a motor to open a window if a temperature reaches a certain level
Data Conversion:
A sensor measures a specific quantity (e.g. temperature) and sends a signal to the computer.
Usually this is an analogue signal so it needs to be converted into digital data for the computer to process.
This is done using by an Analogue-to-Digital Converter (ADC).
Sensors are used extensively to complete every day tasks.
Analogue to Digital converter:
Computers only understand digital which is naught and ones, whereas in the real world, sensors provide analogue signals. An analogue can convert real world data into small increments, infinite possible values. So we use an analogue to digital converter to convert analogue data to digital, so the computer understands.

Digital to analogue converter: this converts data from naught's and ones (what the computer understands) to analogues, which is a real, life value so we can understand it. example.
