Hello,
Has anyone come across a Raspberry Pi-compatible ultra-low temperature sensor that can measure temperatures down to –80°C (or even better, –100°C)? We have some deep freezers at work, and we would like to set up a temperature sensing and logging system for them. We will need to somehow squeeze-in the cable through the rubber between the door and the freezer chasing, so the cable must be relatively thin.
I have found PT100 sensors that can manage low temperatures, e.g. https://www.sensorshop24.de/kabelfuehle ... messer-3mm
For interface with Raspberry I guess RTD data acquisition HAT is needed, for example: https://sequentmicrosystems.com/collect ... rd-for-rpi
Any better ideas? I would greatly appreciate any suggestions and reports on hands-on experience!
