Ever wondered how your car knew if it was hot or cold outside? It’s all thanks to a small thing called the ambient air temperature sensor. This little gizmo makes your car’s heating and cooling systems function more efficiently.
When the weather is really hot, the air conditioning in your car cools you off. When it’s extremely cold, the heating cranks up. The outside air temperature sensor records the temperature and reports it to the car’s computer. The computer then alters the car to help the interior maintain a comfortable temperature.

Your car’s engine also needs the help of the ambient air temperature sensor. It’’s there to help the engine know how much air needs to be mixed with the fuel, which is important for the engine to perform its best. When the outside air temperature does change, the sensor sends a signal to the engine computer, the engine computer makes adjustments to make the engine run well.

Temperature sensor When you go on a pleasure trip on a hot summer day or return to school on a cold day, the outside air temperature sensor is working for you. And just like by regulating the heating and cooling systems and assisting the engine, this small sensor plays a very big role in car comfort and efficiency.

Ambient air temperature sensors may be tiny, but they’re smart tech. These sensors gauge the outdoor temperature and convert that information to an electrical signal that is compatible with the car’s computer. These sensors can be found not only in vehicles but also in heating and air conditioning systems, weather stations and even some smart home products.
