This activity, from the Institution of Engineering and Technology (IET), introduces students to methods of how to identify what components can be used as electronic sensors.
The resource is designed so that students will know that:
• a sensor is a transducer whose electrical characteristics react to an energy transfer
• a sensor is a device which monitors changes in a physical environment
• a sensor is an input transducer
• sensors are part of an electronic system
The role of smart sensors in our everyday lives is becoming increasingly fundamental. The Smart Sensor Communications topic focuses on what smart sensors are, how they are being used today and how they can be innovative in the future. In this activity, the focus is on how sensors can be used to detect changes in the environment and can be used as part of a monitoring or control system.
The activity is supported by an activity sheet in which students match the picture of a component with its description and the podcast Fire which explains how smoke alarms work.
