What is a sensor
A sensor is a piece of equipment that senses or monitors something.
Example : thermometer which is temperature sensors
There are two different types of sensor:
1- Analogue sensors 2- Digital sensors

Analogue sensorIt can measure over
continuous range and their readings may form a curve
Example mercury thermometer
Digital sensorIt jumps between values,
though if the steps are small, they may not be detected by the human eye.
Example: modern desk weather systems

Analogue to digital convertorIf an analogue sensor is used as a computer input ,a device must be used to
convert the analogue signal to a digital format. This device is known as
Analogue to digital convertor

Datalogging
When sensors are attached to a computer that records readings at intervals over time, this is known as datalogging.
