Project Advice with Measuring Temperatures

Post by Living_with_the_lab1 »

Hello,

I'm working with my senior design group, and we have been asked to measure temperatures for our senior design project using an Arduino UNO. As a group, we have never used the Arduino UNO, nor are we familiar with all of the types of sensors the UNO can use to measure temperatures. Our main concern is that our project deals with freezing test samples at extreme temperatures, so we would need to find a sensor that can measure temperatures around negative -175 degrees Celsius. Is this possible? Our professor seems to think that the Arduino can do it, but we have yet to find anyone on the forums that has used an Arduino for a project like ours. If anyone has any advice as to what we type of sensor we should use for this project, please let us know.

Thanks

-175 is possible but you will have to get out the sensor manuals and find one that has that range and can output something the Arduino can read. Start with the companies that make temperature sensors and check their specs.

We have ordered and received a 'Playingwithfusion MAX31855' thermocouple shield and an adafruit SD shield. How can we send information from the thermocouple to the SD shield? We have tried code using I2c but we are not sure if this will work because it hasn't so far. If you have any suggestions please let us know! Thank you.

Can you get the data from the thermocouple to the Uno and then to the serial monitor? If you can do that then the rest should be possible.

Yes, we got the temperature data to be posted on the serial monitor but now we are trying to send the data to the SD shield. We stacked the thermocouple shield on top of the SD shield and we are having trouble debating how to connect these two to get the data stored on to the SD card. If you have any suggestions please let us know! Thank you.

Have you been through the tutorial for the SD shield? There is example code that writes data to the SD card. You can just substitute your thermocouple data for the data in the example.
