Temperature sensors are devices that measure the temperature of an object or environment. They can be found in various forms, such as thermocouples, thermistors, and infrared sensors. These sensors convert temperature readings into electrical signals, which can then be displayed or recorded for monitoring and control purposes. Temperature sensors are widely used in many applications, including HVAC systems, automotive engines, and industrial processes. They help ensure optimal performance and safety by providing accurate temperature data, which is essential for maintaining proper operating conditions in various settings.
