Temperature SensorsTemperature sensors are devices that are used to measure the temperature of a physical object or environment. These sensors can be used in a variety of applications, such as in HVAC systems to control the heating and cooling of a building, in automotive engines to monitor engine temperature, and in medical equipment to monitor body temperature. Temperature sensors typically work by detecting a change in a physical property that is directly related to temperature, such as electrical resistance or the expansion of a material. Some common types of temperature sensors include thermocouples, resistance temperature detectors (RTDs), and thermistors.
