I'm excited to be launching SenseTemp here on Crowd Supply today!
When planning environmental tests of embedded electronics I'm developing, I couldn't find accurate, small, low-cost, and flexible temperature sensors -- so I designed SenseTemp. I'm using it to validate the thermal design around voltage regulators, processors, motor drivers, and other heat-generators in my products.
SenseTemp designed to grow with you -- so it's open source hardware & software and built around the Adafruit Feather standard. The embedded python firmware is easy to modify to expose temperature data the way you want it, and there are a variety of MCU and radio options for it.
Thanks for checking out SenseTemp and I'm excited to see what this great community does with it!
