Monitoring and Control
In a few words, describe what a sensor is?
Sensors: Measuring the World Around Us
Sensors are devices used to measure physical characteristics of the environment, such as temperature, light, and sound. Data captured by sensors is used to monitor, control, and automate tasks in our daily lives. Examples of sensors include temperature probes, pressure gauges, and barometers.
Sensor: A device that detects a physical property and records, indicates, or otherwise responds to it
Data Acquisition: The process of collecting data from sensors and other sources
Data Processing: The analysis of data to extract useful information
Did you know?
Sensors are used by astronauts in space to measure the temperature outside the spacecraft. Some sensors can measure the speed of sound in air. Sensors can measure the water levels in rivers and lakes to detect flooding.
What is a sensor and how does it work?
What are some different types of sensors and what are they used for?
What connections can you make between sensors and the world around us?
What ethical considerations should be taken into account when using sensors?
