BACK IN STOCK – Thermocouple Amplifier (MAX6675) breakout board
Thermocouple Amplifier (MAX6675) breakout board. Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The MAX6675 does everything for you, and can be easily interfaced with any microcontroller, even one without an analog input. This breakout board has the chip and bypass capacitor 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). Goes great with our 1m K-type thermocouple.
Works with any K type thermocouple
0 to 1024 degree C output in 0.25 degree increments
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
I went to wikipedia because I got to wondering about the use of a terminal block as a connection for a thermocouple. The thermocouple wire being of a different composition than the terminal block can, in effect, act like a pair of thermocouples themselves which made me wonder how hard it would be to calibrate this. Seems like you would get measurement drift if the room temperature wasn’t very stable.
