Sub 30$ grow tent controller

Anyways... long story sort, I was not down to dish out 100$ for a tent controller that only talks to periferals of the same brand... so I made my own.

First version was made on an arduino R3 and was pretty messy and bulky, but now on V2 running of an ESP32 the total cost of the unit is just under 30$.

The thang, can control your fans and humidifier to whatever you set as T or RH, displays VPD, can be used as light timer and can control irrigation(for 1 plant atm but got enough pins for 4 left)
