Some parts for luftdaten.info project

thingiverse

The suggestion from luftdaten.info to attach the NodeMCU + Sensor to two HT- pipe elbows is not terrible so far. However, it somehow just sits there... \r\n\r\nFirstly, one can use the holder to secure all parts in place. Using PCB stand-off screws allows you to build it almost suctioned into the pipe. Maybe someone else has a different idea.\r\n\r\nSecondly, two filters can be used to make the pipe outlets insect-proof. The filters have holes for rubber tubing and power supply at the center. I installed hollow bushings in the filter for easy maintenance. \r\n\r\nThe openSCAD files are included, of course. \r\n\r\nThe Pipe-Holder can be found here: https://www.thingiverse.com/thing:2830393
