At this point the module will measure environmental values:
- Temperature, Barometric  pressure, Humidity
- VOCs
- Ambient light and UV light
- Fine Dust PM2.5, PM10
- Sound level
- Acceleration
- NO2, O3, CO2
- Wind Speed and Direction
- Rain
For a few days now a deep search is going on to finalize the m10-sensor (environmental) board. That may take more time than originally planed.
Better R&D will make this board very useful.
- Decisions mast taken for ready sensor modules to place on PCB or individual sensor modules chips.
- Connection types and wiring for the sensors locating outside the main PCB at least meter away (UART for fine dust sensor, Analog high quality sensors, I2C sensors,  2 wire sensors)
Taking account the work done by established companies in the environmental sensing IOT. Among them:
- Adafruit, Grove, Sparkfun, Bosch, Omron, Renesas, ST, Winsen, ScioSense

Some serious projects are taken into account:
- Hackair. EU funded program "Collective Awareness Platforms for Sustainability and Social Innovation". https://www.hackair.eu
- iSCAPE. EU funded program "Horizon 2020". https://www.iscapeproject.eu
- Smartcitizen. Citizen Science Revolution. Fab Lab Barcelona. https://smartcitizen.me
- Luftdaten. https://sensor.community/en
- Sensor community. https://sensor.community/en
- Sensebox. https://sensebox.de
- uRADMonitor. https://www.uradmonitor.com

The above list does not contain what is on planet but it is a starting point. These projects are very professional.
The idea is to build a first version that meets most of our current expectations  and then we see what comes next.
That is to build a solid "brick" on the M10CUBE concept.
