Hi
How to monitor CO2, VOC, temperature, humidity, pressure, dust, light, smoke, motion in a room ?
I know there are consumer products that monitor these things, but I don't want to buy separate devices to track these values.
So I am looking for a DIY solution to have these sensors in a single enclosure.
After doing some initial research, I found out this can be done with an ESP32 controller / ESPhome / home assistant.
I have no clue to start with all this... if someone more experienced is willing to lend a helping hand please?
I am interested in monitoring following values for a few rooms :
-
CO2: MH-Z19B NDIR / SCD30
-
VOC: SGP30 / MICS-6814 / TGS8100
-
temperature / humidity / atmospheric pressure : BME280
-
dust (PM 1 / 2.5 / 10) : PMS7003
-
light / luminosity / lux : TSL2561
-
smoke
-
motion / presence
Is this possible ? If yes, how can I do this ?
A detailed step-by-step guide (like explained to a 10-year old) is much appreciated.
If it's not possible on a single board, what is the max amount of sensors I can combine. Because I don't want to hang 3 boxes in each room 
Things I am wondering or looking for :
-
integration with Home Assistant
-
powered with battery or wire?
-
ESP32 ?
-
mounted in a nice enclosure on the wall
-
easy to replace a sensor (after a few years)
Thank you very much!
