Temperature sensors with analog and digital output are devices that measure temperature and provide a signal that can be read by external systems. They are available in various types, such as thermocouples, resistance temperature detectors (RTDs), thermistors, and semiconductor sensors. These sensors offer accurate temperature measurement, low noise, and high stability, making them suitable for industrial, medical, and scientific applications. Analog outputs provide a continuous signal proportional to temperature, while digital outputs offer discrete values through protocols like I2C or SPI. They are commonly used in HVAC systems, automotive, food processing, and laboratory environments.
