Input devices for the collection of data

Control

The input device you use will depend on the requirement.

Sensor types

Please read this article for a pretty good example of different input devices

The following are some sensors with explanation and example uses:

• Heat: measures temperature, e.g. central heating, fire alarm
• Humidity: measures water vapour in the air, e.g. greenhouses, swimming pool halls
• Infra-red: measures heat (a type of radiation), e.g. security alarm systems
• Light: brightness, e.g. security lights
• pH: acidity levels, e.g. environmental monitoring
• Pressure: force applied on the sensor, e.g. automatic doors, alarm systems
• Smoke: particles in the air, e.g. fire alarm
• Sound: sound pressure level, e.g. noise pollution monitoring, voice controlled systems, alarm systems
• Tilt: angle of tilt, e.g. aircrafts, alarm systems installed in windows
• Touch: more sensitive than pressure/detects contact, e.g. robots

Standards

• Evaluate different input devices for the collection of data in specified situations.

Assess the implications and limitations; make judgments about the ideas, works, solutions or methods in relation to selected criteria.
