Is there a way to run a fan when a room reaches a certain temperature Like a small computer fan that runs off a micro-controller using a thermometer?

There are two main types of thermostats. A cooling thermostat and a heating thermostat.
On a heating thermostat the normally open contacts close when the temperature drops below the thermostats set point.
On a cooling thermostat the normally open contacts close when the temperature rises above the thermostats set point.
Once the cooling thermostat is spliced into the fan circuit all you have to do is set it at the point at which you want the fan to operate. If the room temperature rises above the set point that you set, the fan will operate. Once the temperature drops below the set point that you set it at it will shut off. In these types of thermostats there is a built in differential of about two to three degrees. This means that the fan will not shut off exactly at the set point but above or below the set point depending on what type of thermostat you are using.

How does a thermometer keep your home at a constant temperature?
It doesn't A thermometer doesn't keep your home at a certain temp. a thermometer tells the temp. of a place.
Why would a mercury thermometer not work below -39 degrees Celsius?
A mercury thermometer wouldn't work -39 degrees Celsius because, it would have to be at a certain temperature to get the right calculations and it has to be a certain temperature
Where is a thermometer used?
It is used wherever an individual (or individuals) want to measure the temperature of a certain object.
Where is thermometer used?

What do you use to heat substances to a constant temperature?
You use a thermometer, to measure the temperature. As a guide to know how much heat to apply, the temperature reading must be kept within a certain range, to be constant.
What is the importance a thermometer?
it is important to know the temperature of a certain individual,specific thing and at the same time the temperature of the environment.
What is the purpose of using thermometer when cooking?
Meats require a certain internal temperature, depending on the meat, to determine doneness and being safe to eat.
How does each scales work?
Scales work by measuring things. Thermometer scales work by measuring the temperature of the air and certain liquids for example.
When thermometer is laid ouside the sun does it measure suns temperature or air temperature?
If a thermometer is laid out in direct sunlight, it will not measure the temperature of the air surrounding it. It will measure the temperature of the heat directly reaching it.
What are the disadvantages of shielding a thermometer?
Shielding a thermometer may have some disadvantages, including: Inaccurate readings: If the thermometer is shielded improperly, it may affect the temperature readings by blocking heat or cooling that should be reaching the thermometer. Slow response time: If the thermometer is shielded too much, it may not be able to respond to temperature changes quickly, which can lead to inaccurate readings or delayed readings. Uneven temperature distribution: If the thermometer is shielded, it may not be able to measure the temperature of the surrounding environment accurately, which can lead to uneven temperature distribution. Difficulty in calibration: Shielding the thermometer can make it difficult to calibrate and maintain, which can affect its accuracy over time. Increased cost: Adding a shield to a thermometer may increase the cost of the device and add complexity to its design, which can make it more expensive to produce and maintain. In summary, while shielding a thermometer may be useful in certain circumstances, it can also have some drawbacks that may affect the accuracy and reliability of temperature readings. It is important to consider the specific application and environment before deciding whether to shield a thermometer or not.
Why Temp gauge goes to HOT?
What kind of temperature gauge? If it is a bodily thermometer, the thermometers probably have a maximum temperature they can actually measure, that or whoever designed them knew that above a certain temperature you would just be dead, and thus instead of reading 150 degrees it just says hot. I can't think of another thermometer that would just read out "hot".
Explain why it is necessary to have a standard thermometer?
to make the same type of measurement around world so that there is a universal when measuring certain substances.
