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.

This module provides temperature data in degrees Celsius with a wide range of applications in industrial, scientific, and home automation projects where precision temperature measurement is critical. It also offers cold-junction compensation and fault detection for open thermocouple connections, making it reliable and accurate for continuous use.

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.
