@crusoe, Hi, It's just NodeMCU with humidity sensor, DS18B20 and CO2 sensor (not really. Just air quality sensor but you can aproximate CO2 concentration). Data are sended to adafruit.io to store them and plot them. I can also adjust parameters from there. Then there are 4 relays so i can control lights, both fans and humidifier.
It's not much but it's homemade and that is what i love about it. 😁
Edit-1: And because it's WiFi enabled board, I can also control temperature of the room in which my tent is so the temperature is now relatively constant.
