__**Sensors**__

Sensors designed to moniter temperature, humidity, pressure and other physical quantities provide data used in robotics, environment climate, research and hundreds of the other applications. Even our sense of smell can be simulated with sensors. Such sensors might siin be used to detect spoiled foods, land mines, chemical spills or halitosis.

-Touch sensors (iPad, iPod) -LED sensors (In mouses and security systems) -Heat sensors (Control and monitor heat)
 * What are they used for?**

** Input/output? **

Input

__**Probes**__ Probes are used in science and medical studies. It is used to measure temperature, the pH of something etc. It is a measuring tool.


 * What are they used for?**

-To detect temperature (in supermarkets to moniter temperature so that certain items have the condition required, in hospitals) -To detect pH levels (to make water is safe in bottled water etc.)

__**Real-time data collection**__

Real-time data collection is very important in medical science. It is used to collect data, such as heartbeats, at the moment that is required. It is needed at the present time rather for the future.

-To moniter less serious information, like the temperature in a greenhouse, so that they can adjust it accordlingy at the time so the fruit/veg don't go off.
 * What is it used for?**
 * -**Detect information at the time needed, for example, a hospital will want to moniter a persons heartbeat at the time so they can see how that person is doing.
