Thermocouple Module with MAX31856 IC, a high-precision A/D converter designed for thermocouple signal processing. Thermocouples provide mV-level analog output which cannot be directly read by microcontrollers. This module converts the analog signals into digital data with high accuracy and enables communication with microcontrollers via the SPI protocol. It supports multiple thermocouple types including K, J, N, R, S, T, E, and B, eliminating the need for separate amplifiers or converters for different types. Compatible with various development boards featuring SPI interface support.Key Features: - High-accuracy thermocouple temperature measurements - Automatic linearization and cold-junction compensation - Supports 8 thermocouple types (K, J, N, R, S, T, E, B) - 19-bit temperature resolution (0.0078125°C) - Full-scale linearity: 0.15% max (-20°C to +85°C) - Accuracy: ±0.7°C (from -20°C to +85°C) - Thermocouple input protection up to 45V - Built-in fault detection including open thermocouple, overvoltage, and low-temperature diagnostics - 50Hz / 60Hz noise rejection filtering - TSSOP-14 package - Compact design, lightweight (5.0g) Color: Blue Material: Plastic Package Includes: 1 x MAX31856 Thermocouple Module Note: The actual product color may vary slightly due to lighting and display differences. Dimensional measurements may have a tolerance of ±1-3cm.
