Description Thermocouple Module,It is an A / D converter using the MAX31856 IC. Thermocouples, which measure with high precision, give mV analog output and these signals cannot be detected by microcontrollers. This card converts the signals to digital data with high precision and allows you to transfer them to your microcontroller with SPI communication protocol. Generally, different A / D converters and amplifiers are used for different types of thermocouples, while this module is compatible with all types of thermocouples (K, J, N, R, S, T, E, B). It is compatible with development boards such as for and with the feature of supporting SPI interface.
