A theme park has a game where a player tries to run from the start to the finish without getting wet.
The system for the game uses sensors and a microprocessor to spray water at a player as they run past each sensor.
Describe how the sensors and the microprocessor are used in this system.
A factory uses an automated system to control the temperature of its storage rooms.
The system consists of temperature sensors, a microprocessor, and actuators connected to heaters and cooling units. The sensors monitor the temperature and send the data to the microprocessor. The microprocessor processes the data and activates the heaters or cooling units based on pre-programmed rules.
Explain how the automated system maintains the desired temperature in the storage rooms.
Extract:
A factory uses an automated system to control the temperature of its storage rooms. The system consists of temperature sensors, a microprocessor, and actuators connected to heaters and cooling units. The sensors monitor the temperature and send the data to the microprocessor. The microprocessor processes the data and activates the heaters or cooling units based on pre-programmed rules.
Discuss two advantages and two disadvantages of using such an automated system in the factory.
