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.

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.
