Question

A geyser is a hot spring in which water occasionally boils, sending a tall column of water and steam into the air. A temperature sensor is used to monitor the temperature near the geyser. The data from the sensor is sent to a microprocessor

Explain why the data from the sensor has to be changed before it is read by the microprocessor.

Describe three advantages of using sensors and microprocessors to monitor the temperature in geysers rather than using manual methods.

Answer 1

 

A)    Data received from the sensor needs to be changed because sensors collect data in the form of analog data or real-world data that cannot understand by the microprocessor. Computers are digital and so they can only understand 1 and 0 (binary language). For the conversion of data from analog to digital, we use Analog to Digital converter (ADC) converter. This device converts the collected data of sensors into digital data i.e. 0’s and 1 which can easily be understood by the microprocessor.

 

B)    Advantages of Using Sensor and Microprocessor Rather Than Manual Method:

 

1.      The microprocessor can process data much faster and quicker than a person can. Because of these high speeds they can respond to changes in the control system very quickly.

2.      Sensor readings are more precise and accurate rather than manual methods.

3.      Sensors are easy to operate.

4.      A microprocessor can manage complex calculations and control strategies very easily.

5.      You can easily set your temperature limits by using a sensor that can be controlled by a remote or touchpad.
