Case for SDS011 and Nettigo I/O board with HECA module (GeenHeat AQS) - luftdaten.info
Description
This is a case for SDS011 air quality monitor with Nettigo 0.2.1 I/O board. This alteration is made by https://greenheat.systems More details below: - assembling manual (only in polish language): https://starter-kit.nettigo.pl/2018/12/nettigo-air-monitor-zbuduj-wlasny-czujnik-smogowy-wersja-0-2-1/ - I/O board project: https://easyeda.com/nettigo/Nettigo-Air-Monitor - 0.2.1 kit: https://nettigo.pl/products/nettigo-air-monitor-kit-0-2-1-zbuduj-wlasny-czujnik-smogowy 0.2.1 Nettigo kit includes heater which highly increases measurements accuracy in high humidity environment (over 65%) but the heater works all the time. This is why the case has a slot for Nettigo HECA system, which starts the heater only when the humidity is too high for a proper measurement (HECA works only with Nettigo firmware: https://github.com/nettigo/namf/blob/master/Versions.md). The case also has 4 slots for aluminium radiators (15x14.5x6mm). Key features added to base case project are: - air tunel for air preparation - slots for heater, aluminium radiators and HECA control system - isobox which limits temperature sensor heat influence - brackets for two sensors: DHT22 and BME280 - two covers, one for OLED 1306 screen - SDS011 exhaust air duct Assembly tips: Nettigo 0.2.1 kit needs to be assembled a bit different than showed in the manual. Photo shows an orientation of SDS and I/O board. "aircover" and "heca rails" needs to be glued to the case. "isobox" needs to be glued after positioning SDS011 sensor. Good idea is to use outside and inside 3mm India rubber foam to increase heat separation"
