A temperature sensor, as found in autommatic cookers, toasters, and coffee makers, etc. is simply a switch which cuts the power when a given temperature is achieved. A common switch is one constructed of two dissimilar metal such as copper and nickel. When bonded together and heated, the different linear expansion rates of the two metals causes the bimetal switch to bend, thus breaking the electrical contact in the appliance. When the temperature begins to drop, the bimetal switch begins to straighten out and thus closes the switch re-establishing electrical contact. This sequence is repeated constantly while the appliance is in use.

How does an automatic trash can work?
An automatic trash can works by using sensors to detect movement. One can wave their hand in the line of the sensors, even a few meters away, and the trash can will open automatically, then close when it no longer detects activity.
How does a automatic spark ignitor work on a gas appliance?
An automatic spark ignition (igniter) works by allowing a spark to come on at the same time the gas comes on. The spark ignition module is inside the burner area. The burner should then light.
What temperature do emzymes work best?
the enzymes work best at 37 degree celsius in your body-it depends on the organism you talk about.
What is automatic cross feed mechanism?
An automatic cross feed mechanism is a system used in machinery, particularly in lathes and milling machines, that allows for the automatic movement of the workpiece or tool across the work area. This mechanism ensures consistent and precise feed rates, improving efficiency and accuracy during machining processes. It typically involves a combination of gears, motors, and control systems to synchronize movements, allowing operators to focus on other tasks while the machine performs the work.
How do wind sensors work?
An anemometer is a device that provides information on wind speed and wind pressure. Sonic anemometers measure the wind speed and pressure of sonic pulses that exist between pairs of transducers.
How do pressure cookers work to efficiently cook food under high pressure and temperature?
Pressure cookers work by trapping steam generated from boiling water inside a sealed pot, which increases the pressure and temperature. This high pressure and temperature help cook food faster and more efficiently compared to traditional cooking methods.
How does an automatic trash can work?
An automatic trash can works by using sensors to detect movement. One can wave their hand in the line of the sensors, even a few meters away, and the trash can will open automatically, then close when it no longer detects activity.
How do pressure cookers work and are they really much quicker?
Pressure cookers work because when you increase pressure, water boils at a higher temperature. Water normally boils at 212 degrees F. Under 15psi of pressure (standard in a pressure cooker), it boils at 257 degrees F. Since your food is cooking at a higher temperature, it will cook faster.
How do heat sensors work to detect changes in temperature?
Heat sensors work by detecting infrared radiation emitted by objects. When an object's temperature changes, its infrared radiation also changes. The heat sensor measures these changes in infrared radiation to determine the temperature of the object.
How do the thermometer towers work?
Thermometer towers work by measuring temperature variations at different levels in the atmosphere. They are equipped with multiple sensors at different heights to capture temperature data. As air rises or sinks, it passes over these sensors, allowing scientists to track temperature changes with altitude.
A very simple explanation of working principle of PIR sensor by a very simple example?
The PIR sensors use the detectors or pyroelectric sensors to work. Example include the automatic door openers.
Cons of solar cookers?
Solar cookers stop working at night, and work less well if the sky is heavily overcast.
Can you explain how egg cookers work?
Egg cookers work by boiling the egg while it is placed between the holders. It saves you from breaking all the eggs as you put them in the pot of hot water/
How does the automatic function on a clothes dryer work?
The automatic function on a clothes dryer uses sensors to detect moisture levels in the drum. As the clothes dry, these sensors monitor the humidity and temperature, adjusting the drying time and heat accordingly. Once the moisture drops below a certain threshold, the dryer automatically shuts off, preventing over-drying and saving energy. This feature helps ensure that clothes are dried efficiently while minimizing the risk of damage.
To do some transmission work on your 1993 Honda accord it is an automatic and you need to replace some sensors?
You need to change the controll silenoid it cost $220.00
What are some ways solar cookers work?

Why do parking sensors and tire pressure sensors not work correctly in extreme cold weather?
Pressure sensors work in all weather. In winter, the air temperature inside and outside the tire is lower. Lower temperature results in reduced air volume which causes the tire pressure to reduce. This in turn will trigger a sensor fault. Just need to add air pressure back to specification
