temp readings

Post by Picaboo »

I am new to the device and setting up the data logger for time and temperature. Why are my temp readings 528 if I have it set for temp in degrees celsius? I am at room temperature.

What temperature sensor are you using? And what processor? Please post photos showing all of your soldering and connections.

I am using the temp sensor that is part of the CPX itself. Not an attached sensor.

I tried both of these and had the same issue.

You may need to include a pause after each line is written to the datalogger. Do you get proper values if you run the program shown in this guide? https://learn.adafruit.com/data-logging ... logger-use

Thanks. I am getting real readings now. Some more questions:
1. Is there any way to get a new log.csv file so that it doesn't just keep adding to the same one?
2. Can you explain what this does? See attached orange block.
3. Finally, why didn't this code give me any data? See attached.
