MAX31855 ,Thermocouple to Digital Converter Module - SPI Interface

The MAX31855 is a sophisticated thermocouple-to-digital converter with a built-in 14-bit analog-to-digital converter (ADC). Designed to work with K-type thermocouples, it accurately measures temperatures and converts the analog thermocouple signal into a digital reading. The module communicates via SPI interface, making it ideal for integration with microcontrollers such as Arduino, Raspberry Pi, and others.

Key Features :

• Wide Temperature Range: Measures from -200C to +700C for the thermocouple input.
• Integrated Cold-Junction Compensation: Provides accurate temperature readings even with temperature variations at the cold junction.
• Fault Detection: Detects open thermocouple or fault conditions.
• 14-Bit Resolution: Provides precise temperature data with a 0.25C resolution.
• SPI Interface: Allows easy communication with most microcontrollers, reducing the number of I/O pins required.
• Compact and Easy to Use: Small footprint, ideal for prototyping and integration into projects.
