Most digital systems follow the input-process-output model: information comes in, is processed, and produces a result. The input stage is where sensors do their work. A sensor detects a change in the environment, such as light, sound, movement or temperature, and feeds that data into the system for the processing that follows.
Different sensors detect different things. The sensors themselves are defined in A3.4.7; here the job is to match each one to an application.
| Sensor type | What it detects | Example use |
|---|---|---|
| Accelerometer | Motion, tilt, vibration | Step counter in smartwatches |
| Ultrasonic | Distance, proximity | Parking sensors in cars |
| Photoresistor | Light levels | Auto-brightness in phone screens |
| Voltage sensor | Voltage, electrical levels | Soil moisture monitoring |
| Hygrometer | Humidity and air temperature | Smart thermostats, weather stations |
| Pressure sensor | Atmospheric (barometric) pressure | Altimeters in drones or aircraft |
| Microphone | Sound, audio waves | Voice commands in smart speakers |
| Infrared sensor | Heat, radiation | Motion detection in security systems |
Choosing the right sensor means matching it to the application. Weigh the accuracy it needs, the range it must cover, and the environmental conditions it will face.
