MAX31855 K Thermocouple Temperature Sensor Module

MAX31855 Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The MAX31855K does everything for you and can be easily interfaced with any microcontroller, even one without an analog input. This breakout board has the chip itself, a 3.3V regulator with 10uF bypass capacitors, and level shifting circuitry, all assembled and tested. Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perfboard).

Features:

• Works with any K type thermocouple
• Will not work with any other kind of thermocouple other than K type
• -200°C to 1350°C output in 0.25-degree increments – note that K thermocouples have about ±2°C to ±6°C accuracy
• Internal temperature reading
• 3.3 to 5v power supply and logic level compliance!
• SPI data output requires any 3 digital I/O pins.

Note:

• Works with any K type thermocouple
• K thermocouples have about ±2°C to ±6°C accuracy
• Internal temperature reading
• 3 to 5v power supply and logic level compliant!
• SPI data output requires any 3 digital I/O pins.

The MAX31855 GND and T- cannot be connected because there is a control switch inside.
