Ultimately, heat sensors provide a measurement of the heat of a given process or area. This has applications in food processing, medical devices, chemical handling and automotive monitoring.

In food processing, heat sensors find use in detecting whether a system is keeping food in a safe temperature range. Heat sensors in ovens help the appliance to switch the burners on or off, and they help maintain the desired temperature in refrigerators and other food preservation appliances.

Medical devices use heat sensors for detecting a range of human body temperatures. This comes in the form of handheld thermometers, which find use in households and hospitals alike.

The use of certain chemicals requires the precision that comes with heat sensors. Automatic heat sensors provide precise measurements that help users regulate and maintain chemicals properly, such as by storing them within a given temperature range.

Heat sensors in vehicles find use by monitoring the temperature of the engine. When an engine overheats, it provides a signal to the driver that something is wrong. Some systems perform emergency shutdowns if the engine overheats in order to prevent damage to the whole system.
