Freezer Temp Sensor by jrucker2004

Last crawled date: 3 years ago

My freezer stops working every once in a while, so I made this to alert me when it happens.
The stl files are just an enclosure for a raspberry pi zero, and a holder for a DS18B20 temperature sensor. I don't plan on including tutorials for setting it up, however my code is on github, and I've linked to some resources there: https://github.com/jrucker2004/freezer_temp_alert
The enclosure and sensor holder are meant to be partially printed, and paused so magnets can be inserted into the print before the print continues. I used the small round magnets from harbor freight.
Things you'll need:
A raspberry pi zero w
A power supply for the pi
Four screws to hold the pi in the enclosure (I used 4-40 x 3/16")
