By Marco Ventimiglia on August 7, 2022
With hydroponic cultivation we imply a special methodology of plant development, in actual fact as a substitute of the earth there may be water with dissolved mineral salts that flows between the roots. On this challenge we are going to see how a hydroponic greenhouse managed by an ESP8266 was constructed.
The system consists of pumps and temperature sensors managed by a NodeMCU with ESP8266. The microcontroller is related to an I/O port expander which in flip is related to a 16 relay module to be able to activate units that function at mains voltages. There are additionally 2 1.3 “OLED shows and an RTC module for actual time holding.
