🌡️ SainSmart MAX6675 Thermocouple Temperature Sensor for Furnace & Kiln Measurement, Range 0-1024℃ Review

Worked great just had to define the digital pins to account for spi. So far dht22 looks like garbage as my Arduino wasn't stuck with a read every second - combine this with a red node and it's just a solid hand down setup will buy again. I will use this probe to control the installation of a boiler for a wood burning stove.

I bought this item to experiment with a future product using an ATtiny microcontroller and a MAX6675 sensor. The MCU will not have a hardware SPI interface, so I access this part via digital I/O pins and software SPI - see the MAX6675 datasheet for signal details. This method was easily accessible via three I/O pins and works over a very wide range of clock speeds (important as this will be a low power design). I've only tested this part at room and body temperature so I can't comment on how it

I ordered one of these. The first shows about 45 degrees higher than it should, so I asked for a replacement. The second doesn't work at all. I'm two and don't have a working sensor yet. If anyone decides to buy one of these, note that it comes with no documentation. Documentation is hard to find online, but I was able to find the Adafruit project on Github: https://github.com/adafruit/Adafruit-MAX31855-libraryEDIT - DO NOT USE THIS LIBRARY - SEE. UPDATE BELOW. You can start by connecting the…
