If I can use a $15 pine64 board in a case that has a large battery (to lengthen times between charging), plus the sensors it'd be far cheaper than what is commercially available. Ideally I'd like to have a wifi receiver on the outside of my office to collect the data from the sensors, then send to a laptop. This will be for monitoring, and also for remote alerts of warm temps caused by a power plant failure so I can try and save the ice while the issue is resolved with the ice plant.

I have a big need for accurate temp and humidity sensors that can transmit data back to a host computer (preferably over wifi), but the temp sensor needs to be a probe that can accurately read ice temperature to 0.1FI think I found the board you are looking for:

And there is a temperature and humidity sensor plugin:

However there is no temperature probe or any one that I know of that has a I2C interface. Adafruit sells a temperature probe that is designed to be directly interfaced to a computer that I think has the accuracy you need:

I do not know if it can be interfaced to the WiFi remote board.
I'm assuming this would be a good humidity sensor? https://www.adafruit.com/products/1293
