MCP9600

Post by sidc209 »

Hello,

So recently I have been trying to get temperature readings and got a thermocouple. I am using a Raspberry Pi to obtain the information and since I have many other sensors attached to the pi, I have a multiplexer helping me do the job. My problem arises when first-off the pi does not detect the thermocouple majority of the time. Secondly, when it does detect, I have tried to run the recommended python scripts off of the adafruit website and they give me errors that no sensors are detected. I have tried to troubleshoot by replacing wires, rebooting, changing frequency in code, however, none have been successful. Furthermore, to rule out the multiplexer as the problematic sensor, I tried to attach the thermocouple to the raspberry pi directly. The pi detected the thermocouple, however, when the adiafruit python code ran, it resulted in an error that read "NO I2C device at address 0x67", where the thermocouple should be.
