A normal PC has no senses, but we can give it some: We can connect sensors to it...
A sensor is a device that converts a real-world property (e.g. temperature) into data that a computer can process.
Examples of sensors and the properties they detect are...
|Sensor||What it Detects|
|Light||Light / dark|
|Pressure||Pressure (e.g. someone standing on it)|
|Moisture||Dampness / dryness|
|Water-level||How full / empty a container is|
|Proximity||How close / far something is|
|Switch or button||If something is touching / pressing it|
Sensors are used extensively in monitoring / measuring / data logging systems, and also in computer control systems.
