MAX31855 hőelem modul hőmérséklet mérő érzékelő magas hőmérséklet mérés K-típusú hőelem modul fejlesztés
MAX31855 thermocouple module temperature measurement sensor high temperature measurement K-type thermocouple module development
MAX31855 has cold junction compensation, which converts K, J, N, T or E thermocouple signals into digital quantities. The device outputs 14-bit signed data, which is output in read-only format through an SPITM compatible interface. The temperature resolution of the converter is 0.25°C, the highest temperature reading is 1800°C, and the lowest temperature reading is -270°C. For K-type thermocouples, the temperature range is -200°C to 700°C, maintaining an accuracy of ±2°C.
Description:
1. Measuring temperature range: minus 200 degrees Celsius to above zero 1350 degrees Celsius
2. Applicable probe, K-type thermocouple, module is not matched, need to be purchased separately
3. SPI interface, high-speed transmission
Four, input voltage 3-5v DC
5. Direct digital output temperature value without amplifier or ADC
Six, 14-bit resolution, 0.25 degree temperature accuracy

Description
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).
New! Now uses the MAX31855K instead of the MAX6675, so it can measure a wider temperature measurement range. Please note! the MAX31855 is not pin compatible or drop-in code compatible with the MAX6675. We do have an Arduino library for both chips but you'll need to adjust any existing MAX6675 designs for the mew MAX31855. The MAX6675 has been discontinued by Maxim.
Version 2.0 now includes ferrite beads and filter capacitor onboard for better stability
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 compliant!
SPI data output requires any 3 digital I/O pins.
