Thermostats are devices that regulate the temperature inside a building or room. They are usually placed near water heaters, furnaces, air conditioners, refrigerators, ovens, etc., and allow the user to adjust the temperature accordingly.
There are two types of thermostats: analog and digital. Analog thermostats work by sensing the temperature of the air and then turning the heating/cooling unit off or on based on the temperature. Digital thermostats work similarly but instead of using temperature sensors they use microprocessors to read the current temperature and then turn the heating/cooling device on or off.
A pressure switch is an electrical device that opens or closes a circuit depending on whether the internal pressure of a container exceeds a certain threshold level. A typical example would be a gas tank where the pressure sensor is connected to a valve that opens when the pressure reaches a predetermined level. When the valve is opened, it allows fuel to flow into the vehicle. This type of switch is commonly used to prevent a car from running dry.

Temperature sensors measure the ambient temperature and send signals to the central controller indicating whether the temperature is above or below a specified value. The most common application of this is to detect overheating of electronic components. Many modern vehicles now use thermistors to monitor the interior temperature of the passenger compartment. The thermistor sends a signal to the heater control module which turns the heater on or off.
