The use of a sensor may seem pointless, since you can always see the weather using any gadget. This is true, however, the weather tends to change, and it will be far from the same as in the morning. The sensor readings will be especially useful for those who make long journeys. These are taxi drivers, intercity buses, truckers.

Also, based on the readings of the METZGER brand Sensor, exterior temperature, you can set the required temperature in the passenger compartment. For example, if it is 5 ° C outside, the interior can be set to about 20 ° C. This approach will also help save fuel.

The functionality of the exterior temperature sensor

In some models, the outside temperature meter is also responsible for the operation of the stove. If the sensor is defective and shows a minus temperature, then when the airflow is turned on, the stove is automatically turned on to warm up the cooling interior.

All temperature sensors have the same operating principle. The effect of changing the resistance value of a semiconductor element on temperature is taken as a basis: with an increase in temperature, resistance indicators decrease.
