Wemos Weather Station w/ Remote Sensor

thingiverse

Delphius_JD did a good job creating the weather station for a Wemos D1 Mini and BME280 chip. https://www.thingiverse.com/Delphius_JD I used a larger 6-pin BME280 and was pleased to discover the Fusion360 compatible model included parametric design parameters for the BME280. I just changed the dimensions for the BME280 and the design was set for my board. I did find that the proximity of the BME and WEMOS board caused the temp to rise in my case by 4-8 deg F. I tested the WEMOS board with a laser temperature reader and found the 8266 wifi chip for the wemos board to be 90 deg F. To solve my temp problem, I created a 'sensor' case by slicing off that part of the design and connecting the two cases with a 4-conductor telephone cable. I also added a few more vent holes. The final result performed well. For future designs I would reduce the size of the main unit but for my purposes, the larger case was not a problem. I printed without supports using fine resolution setting.
