A security light system is used by a factory. The light only comes on when it is dark and when movement is detected. The light will stay on for 1 minute before switching off. Sensors and a microprocessor are used to control the security light system. Identify two sensors that would be used in the security light system. Sensor 1 Sensor 2 Describe how the sensors and the microprocessor control the security light system.

A farmer has a plough that is an automated system. The plough is used to dig the ground in a field to prepare it for planting seeds. The plough uses sensors and a microprocessor to maintain a straight line when digging the ground. State what is meant by an automated system. Describe the role of the microprocessor in this process. Give two benefits to the farmer of using an automated system for this purpose. The plough uses artificial intelligence (Ato navigate its way around the field. Explain how the plough makes use of AI for this purpose.
