Temperature sensors are devices that detect and measure temperature changes and convert them into an electrical signal that can be monitored, displayed, or used for control. They are available in various technologies, including thermistors, RTDs, thermocouples, and semiconductor-based sensors, each suited to different temperature ranges and accuracy requirements.

Temperature sensors are widely used in industrial automation, HVAC systems, automotive electronics, medical equipment, consumer devices, and environmental monitoring.

Key advantages: accurate temperature measurement, fast response, reliable operation, compact designs, and compatibility with both analog and digital control systems.
