Freezer Temp Sensor

thingiverse

I made this alert system to notify me when my freezer stops working, which happens every now and then. The stl files for this project are designed as enclosures for a raspberry pi zero and holders for DS18B20 temperature sensors. My code is available on github, along with some useful resources, at https://github.com/jrucker2004/freezer_temp_alert. The enclosure and sensor holder are meant to be partially printed, then paused so that magnets can be inserted into the print before it continues. I used small round magnets from harbor freight. Here's what you'll need: * A raspberry pi zero w * A power supply for the pi * Four screws to hold the pi in place (I used 4-40 x 3/16") * A temp sensor: https://www.amazon.com/gp/product/B00Q9YBIJI/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 * A resistor: https://www.amazon.com/gp/product/B0185FGYY2/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 * Some magnets: https://www.harborfreight.com/10-piece-rare-earth-magnets-67488.html
