MAX31855 Thermocouple Interface


Out of stock

SKU: WTP171201 Category:


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.

This module also includes level shifting circuits which allow it to be connected to a 5 volt microcontroller such as most Arduino compatibles.
