#Luftdata? I'm part of a Swedish Citizen science projekt luftdata.se measuring air particles using a sds011 sensor. It's a branch from the original german projekt luftdaten.info where you can read build instructions etc in English. (You can of course also use the model to measure to other things then particle measurements, I've printed one identical where I have a BME280, BH1750 and a external tipping bucket for rain thus making my own weather station!) You can see a live map of all the particle readings here The original case is made of 2 pieces 87° sewer pipes and that's a cheap and sturdy solution but I wanted something that looked a bit better on my wall so I designed this stevensson screen sensor holder. It fits the sds011 sensor and a DHT22/BME280 besides the mandatory nodeMCU/WemosD1 Stevensson what? A Stevenson screen or instrument shelter is a shelter or an enclosure to shield meteorological instruments against precipitation and direct heat radiation from outside sources, while still allowing air to circulate freely around them. You have probably seen some around in the world without thinking about it but it was first designed at the end of 1880! Parts It's enough with 2 bolts to keep it together but if you want to be on the really super safe side it's designed to use 4 bolts. I recommend that you get stainless bolts and nuts since it'll be placed outside. Printed parts 6x middle part 1x wall bottom part 1x top part 1x sds011 holder Bought parts 2-4x M8x100mm bolts 2-4x M8 nuts 2x wood screws
