A device that gives an output by detecting changes in quantities or events can be defined as a sensor. In general, sensors are called devices that generate an electrical signal or an optical output signal corresponding to variations in the level of the inputs. There are different types of sensors.
For example, consider a thermocouple which can be thought of as a temperature sensor that produces an output voltage based on input temperature changes.
Different types of sensors in electronics
In our daily life, we used to frequently implement different types of sensors in our power systems such as electrical and electronic devices, load control systems, home or industrial automation, etc.
All types of sensors are classified into analog sensors and digital sensors. But, there are a few types of sensors such as Humidity Sensor, Temperature Sensor, CO2 Sensor, IR Sensor, and Pressure these are frequently used in most electronics applications.
