Case for Air Quality Monitor ===================== based on https://sensor.community design added user guide (Installation and settings) — Russian version only so far, sorry. Versions ----------- Seals and Base are common for all versions of controller. Lid comes in three versions for different models of controller boards: * esp8266 v2 ('narrow' 30 pin board) * esp8266 v3 ('wide' 30 pin board) * esp8266 D1 mini (small 16 pin board) Print only the lid you need Sensors ----------- * Nova Fitness SDS011 Fine particulate matter sensor * Bosch BME280 Temperature/Humidity/Pressure sensor or * HTU21D Temperature/Humidity sensor Printing ---------- Case has 2 parts, lid and base and number of seals. * Use PET-G or ABS or ASA for base and lid. If PET-G or ABS is used cover parts with UV-protective paint. Cover should be white (plastic or paint) or very light colored to prevent heating of the sensor. * Use the softest available TPU to pring seals. If the seals not flexible enough apply additional sealant on top of the case to prevent leakage. All the seals come in one print.
