Usually the fan will turn on when a certain heat is reached.
An air temperature sensor in an automobile is very important. The temperature sensor detects the external temperature. The external temperature is important because of the manner in which the car's computer mixes air and water.
A special sensor or transducer called a thermistor is used to detect an increase in the temperature of the surrounding air whenever smoke is produced by a fire. A different type of sensor is used to detect an increase in the size and density of particles in the surrounding air after it has been contaminated by smoke from a fire. Either sensor gives an output in the form of an increase in voltage whenever it detects an increased temperature and/or smoke particles. That increase in voltage is fed to the base of a transistor. When the voltage to its base increases, the current from the transistor's emitter to collector (or from its collector to emitter) increases and that increase in current operates the alarm. In other words, in a fire alarm circuit, the transistor acts as a switch which turns on the alarm whenever a sensor or transducer detects the presence of a fire, else it remains off.
There is a sensor that detects temperature to turn the fan on in some vehicles, this sensor may need to be replaced.

No, the temperature sensor switch and the fan switch are not the same. The temperature sensor switch detects the temperature of a system (like an engine or HVAC) and sends a signal to activate or deactivate other components based on that temperature. In contrast, the fan switch specifically controls the operation of a fan, either turning it on or off in response to signals from the temperature sensor or other controls.
It is a sensor that measures/ detects oxides of nitrogen.
A heat sensor in a furnace detects the temperature inside the furnace. When the temperature reaches a certain level, the sensor signals the furnace to either turn on or off to maintain the desired temperature. This helps regulate the temperature and ensures the furnace operates efficiently by preventing overheating or underheating.
An infrared sensor detects infrared radiation emitted by objects based on their temperature. It can detect heat signatures, motion, and proximity by measuring changes in infrared light levels.
The Ford Zx2, all years do not have an air intake temperature sensor. The MAF sensor/mass air flow sensor detects both the air temperature, and the air volume being inducted. The MAF sensor is located in the air cleaner box near where the hose goes toward the engine, and will have a bundle of wires going into it.
Not wanting to state the obvious here, but it's a sensor that detects the ambient (outside) temperature. This then links through to a light on the dash and is used to warn you of a possible risk of ice. HTH
The knock sensor detects spark knock or ping.
A sensor is a device that detects a physical property and converts it into an electrical signal, such as temperature or pressure. A detector is a device that specifically detects the presence of something, such as a gas or a substance, without necessarily converting it into an electrical signal. In essence, a detector is a type of sensor that focuses on detecting a particular target or substance.
