Thermal Sensor Relay Module (MAX6675)

The MAX6675 Thermocouple Sensor Module uses K-Type Thermocouples and converts the data into digital format and provides data to SPI interfaces. The sensor is useful to provide accurate temperature-compensated measurement of the supplied K-Type thermocouple sensor. The data output in a 12-bit resolution, SPI compatible, read-only format. The MAX6675 converter has a resolution of 0.25°C temperature. It allows readings as high as +1024°C, and exhibits thermocouple accuracy of 8 LSBs for temperatures ranging from 0°C to +700°C. The working voltage is 5V and the measurement accuracy is ± 1.5 °C.
