I desired to monitor more than one room without buying multiple expensive devices. This enclosure is designed to fit 3 devices: 1. a PM2.5/PM10 dust sensor 2. a Wemos ESP8266-based board with an OLED display 3. a digital humidity and temperature sensor # Parts * Wemos NodeMCU with an OLED display The central component of this project. It provides processing, connectivity, and instant data feed on the display.

Print the parts (I used 2 colors per part with [ColorPrint](https://www.prusaprinters.org/color-print/)) 2. Connect SDS011 to Wemos board 3. Connect DHT22 to Wemos board 4. Use 4x shorter screws to mount the Wemos board to the front plate 5. Use 4x longer screws to keep the front and back plates together 6. Flash Wemos board with [ESPEasy](https://github.com/letscontrolit/ESPEasy) 7. Configure devices in ESPeasy # Summary When fully assembled, it should be comparable to retail products such as: * [Xiaomi PM2.5 detector](https://www.banggood.com/Original-Xiaomi-Mijia-PM2_5-Detector-Air-Quality-Tester-Monitor-OLED-Smart-Sensor-Air-Purifier-p-1330361.html?p=X314102609367201509L&custlinkid=113893) * [SNDWAY SW-825 Digital Air Quality Monitor](https://www.banggood.com/SNDWAY-SW-825-Digital-Air-Quality-Monitor-Laser-PM2_5-Detector-Gas-Temperature-Humidity-Monitor-p-1244753.html?p=X314102609367201509L&custlinkid=113888) # Please feel free to propose improvements https://github.com/wojked/dust-sensor
