Can't find the air quality sensor on their bill of materials

• shrx 4y ago
  The Readme file [1] on their GitHub repo contains this bill of materials: https://docs.google.com/spreadsheets/d/1-fR-0hTxHKbjaRf8DbH62WgUFVeNE4eUEsaAd-YdDYg/edit#gid=2089068555 https://docs.google.com/spreadsheets/d/1-fR-0hTxHKbjaRf8DbH6... This lists a "particle module", a temperature sensor and some other seemingly irrelevant sensors (GPS, accelerometer). [1] https://github.com/MIT-Senseable-City-Lab/OSCS/tree/main/Build/Hardware/Hardware%20schematics https://github.com/MIT-Senseable-City-Lab/OSCS/tree/main/Bui... edit: looks like the "particle module" is just a LTE/BT communication module, so really there don't seem to be any environmental sensors other than for temperature.

    You are only looking at the list for the main board, the air quality sensor carrier is the second sheet of the doc.

      Thanks!

      It only includes a particulate matter sensor and "Analogue Front End (AFE) Alphasense A4 Air Quality Gas Sensors" but not the sensors to use.

  There's a mention of the SEN5X here: https://github.com/MIT-Senseable-City-Lab/OSCS/blob/main/Build/Hardware/Hardware%20schematics/Flatburn-sensor-board.pdf https://github.com/MIT-Senseable-City-Lab/OSCS/blob/main/Bui...

  The particulate sensor is Sensirion SPS30, mentioned on the AQ Ext Board tab in the spreadsheet.
