The block diagram for logging the data of humidity for a warehouse is shown below

It mainly contains four major systems:
1.   Humidity sensor
This sensor is mainly used for sensing the humidity of the warehouse. It basically senses the relative humidity. The measuring principle is based on the well-known capacitive mechanism. Hence, the output of this sensor is analog.
2.   Microcontroller board (ADC converter)
To convert the analog signals as sense by the humidity sensor into its equivalent digital signals, a microcontroller should be used that consists of an analog-to-digital converter. The ADC converter is used to convert the signal; however, the microcontroller is forming a gateway to storage the captured data.
3.   Serial port
To send the data from the microcontroller to the storage device, we need a serial port that passes on the digitized data into a storage device such as PC.
4.   Storage device
This component is used to store the captured data. Typically, a computer has been used in this aspect.
Differentiate between transducer and sensor
The sensor is used convert the physical signal into its corresponding electrical signals; on the other hand, the actuator is used to convert the electrical signals into its equivalent mechanical work.
For example: a robotic manipulator; where mostly vision sensor is used to locate a device, the distance of that device from the manipulator etc. Using that information, the robotic manipulator i.e. the actuation system is tried to hold that object.
In a temperature control system, the temperature sensor is used to sense the ambient temperature. Based on that sensing information, the actuators such as air cooler or heater are triggered.
