I wanted to put some I2C sensors outside, but I2C devices need to be close to the master so the Zero went outside also.
Currentlyon have DS18B20, TSL2561, and BMP180 attached.
I do have a trigger set for the case internal temperature as it gets very warm inside the box with the sun beating down on it all day long.
Here’s a link to the project on Hackster.io
All the parts ready to assemble.
