Sensors

• There is a wide range of control systems in which sensors act as analogue inputs. The analogue signal is converted to digital form (for processing) by an analogue to digital converter (ADC).
• Many systems make use of sensors, including robotics systems, building control systems, and flight control systems, for example. There are many different types of sensor. For example, mobile phones can have a wide range of sensors, including accelerometers, altimeter, gyroscopes, compass/magnetometers, GPS receivers, barometers, thermometer proximity sensors, and ambient light sensors.
