co2 box case

Board: ESP8266 Lolin D1 Mini Pro: because it's cheap, compact, enough CPU power, sufficient IO. See also my previous post
CO2: Winsen MH-Z19b, reasonable price/quality ratio, measures direct CO2 (vs equivalent CO2 like AMS CSS811), see also in my previous post
T/RH/P: Bosch BME280: very good price/quality ratio, see also this definitive guide
Screen: 1.3" I2C 128x64 pixel OLED display, reasonable size and price, I2C is easy to work with.
OS: ESPHome, similar to ESPEasy but I like it a bit better because it builds on existing platformio backbone. See also this comparison
Mounting: perspex with m2/m3/m4 bolts
