Soil Geeking @ Lifepatch with Matt
Great opportunity to do some testing and sharing of protocols with Matthew Daniel from Global Urban Forest. This turned out to be a great little gathering of overlapping networks from GOSH, our-sci, hackteria and the local soil, gardening and permaculture geeks around Lifepatch.
Testing trials in lifepatch garden
Visit to Pak Paning's permaculture farm
Early Experiments
First Prototypes
Comparing sensors and chambers

MH-Z16, available with an I2C board:
MH-Z19:
New Library!: https://github.com/WifWaf/MH-Z19
This page is about the MH-Z19 CO2 sensor and some experiments done with it:
Using the MH-Z19 CO2 sensor PWM readout, simple arduino code:
More on ABC, Automatic Baseline Correction
Immerhin kann man den Sensor per Hd-Pin (7s gegen GND) auf 400ppm (Außenluft) eichen.
CCS811
CCS BME combo
This one I ordered 2.... but check I2C adress. and connect "WAK" to GND
- #define CCS811_ADDR 0x5A //Alternate I2C Address
- myBME280.settings.I2CAddress = 0x76;
