Not a thermometer as such - but there is a temperature sensor on most computer motherboards to monitor the CPU temperature.
Purchase a good quality thermometer specific to the type of temperature you need to monitor; IE: Medical, cooking, pool or fish tank. There are different type, but digital thermometors are the most accurate.
-- Bring thermometer into room. -- Wave it around in the air of the room for a minute or two. -- Do not hold the thermometer in your hand or breathe on it. -- Wait a while for the room temperature to get through the thermometer glass. -- Look through the glass at the sliver of liquid inside the thermometer. Find the end of the liquid, and see what number is marked on the glass at the same level. That number is your room temperature.
The sticker type thermometers are not very accurate and tend to be affected by external temperatures. To better monitor your tank water temperature, you can buy a thermometer that sticks on the inside with suction cups
what does monitor means?Monitor means in science to keep on checking on something over a period of time.
measuring heat..."thermo" as in "thermal" means heat, and a meter is a measuring device...so a thermo-meter or a thermometer is a device that measures heat.

The LCD thermometers work much the same way as a bimetallic thermometer, only the circuitry inside the electronic thermometer measures the temperature through resistance. Through expansion, the device will have a higher resistance in higher temperatures, and the computer inside will make note of that. The temperature it derives is then displayed on an LCD screen. Then it works. http://www.dinodirect.com/Components/LCD-Monitor
