Hi, I would be very interested to buy climate, liquid and gas sensors and controllers. Currently these can be very expensive for makers/hobby market, but we don't need such expensive high resolution items for prototypes. Orange boards are great for experimenters.
I am building different projects for greenhouse and garden applications.
Currently I am using sensors for pH, EC, Temp (air and liquid), Humidity, CO2, Oxygen (in liquid and gas).
Thanks
Charlie
