K Type Thermocouple MAX6675 Module for Arduino

K Type Thermocouple Temperature Sensor with MAX6675 Module  for Arduino

K-Thermocouple- to-Digital Converter (0C to +1024C)


Working voltage: DC5V     Operating Current: 50mA

Temperature measuring range: -200 C - 1300 C [Test procedure for 0-1023 C]

Temperature measurement accuracy: 1.5 C

Temperature resolution: 0.25 C

Output mode: SPI digital signal

Storage temperature: -50 ~ 150 C

Module weight: 4g   size: 25mm * 15mm * 13mm

• On-chip cold junction compensation.

• High-impedance differential inputs.

• Fast response and High sensitivity

MAX6675 is a 12-bit resolution Serial K-type thermocouple to digital converter, produced by MAXIM,
with merits of cold junction compensation, linearity correction, thermocouple break detection and so on.

Based on the principle of the chip, this module is available to measure temperature, using the
three-wire SPI communication, plus a K-type thermocouple probe connected to Arduino mainboard.

Measurement results can be displayed in Arduino IDE. Module can be used in room temperature measurement,
also refrigerator, power room, textile machinery, air conditioners and other small space
industrial equipment temperature measurement .
