in shortest time I want a small PCB that can read indoor air parameters such as:
air temperature, humidity, atmospheric pressure, CO2 (dioxyde), VOD, visible light intensity (even UV if possible).
Sensors must be SMD type and must communicate to the MCU(arduino like/ESP8266/raspberry) via I2C so that an user can chain more than a such PCB on the same MCU pins. Components can be cheap but reliable.
Connector on the PCB has to be JST HX type.
A short demonstration coding to put the PCB at work upon delivery is also required.
Schematics and BOM must be available, better if in KiCAD format.
