The Arduino MKR Therm Shield is a specialized expansion board designed specifically for the MKR family of Arduino boards. This board is designed to accurately acquire temperatures from various sensors, including type K thermocouples and digital DS18Bxx one-wire sensors.

One of the key features of the MKR Therm Shield is its ability to manage the analog nature of thermocouples, which requires a specific interface. Using the digital interface MAX31855, it converts analog signals into digital data, making direct temperature measurements easy.

The shield also supports a wide range of temperatures, making it suitable for industrial and laboratory applications. Key features are listed below:

• Connectors: Type K thermocouple connectors and digital Dallas DS18S20 thermometer connections.
• Input voltage: Operates at 3.3V, aligning with the standards of MKR boards.
• Operating temperature: Ranges from -200°C to 700°C.
• Communication: Supports SPI and 1Wire protocols for efficient data transfer.

Additionally, with the open-source hardware design, users can create custom setups using the provided EAGLE files. The MKR Therm Shield stands out as an accurate and reliable temperature measurement solution within the MKR family.
