MAX31855 Module K Type Temperature Sensor Module

The MAX31855 performs cold-junction compensation and digitizes the signal from a K-type thermocouple. The data is output in a signed 14-bit, SPI-compatible, read-only format. This converter resolves temperatures to 0.25°C, allows readings as high as +1800°C and as low as -270°C, and exhibits thermocouple accuracy of ±2°C for temperatures ranging from -200°C to +700°C for K-type thermocouples. For full range accuracies and other thermocouple types, see the Thermal Characteristics specifications. Integration Reduces Design Time and Lowers System Cost, 14-Bit, 0.25°C Resolution Converter, Integrated Cold-Junction Compensation, Detects Thermocouple Shorts to GND or VCC, • Detects Open Thermocouple, Interfaces to Most Microcontrollers, Simple SPI-Compatible Interface.
