ESP8266 WiFi Smart Irrigation System based on Souliss IoT Framework

Bill of Material:

n.1 PCB
n.1 Esp-12 E/F
n.1 resistor 1k
n.1 cap 1000mf
n.1 2/4/8 relay board (optoisolated)
n.1 Soil Hygrometer Humidity Detection Module (optional)
n.1 LM2596 step down dc-dc board
n.1 AMS1117 3.3v
n.2/4/8 12v valve like FPD-270A
n.1 12v power supply (2/4A)
n.1 enclosure ip68

How to connect your system:

use lm2596 to step down from 12v to 5v and power on relay board
use ams1117 to step down from 5v to 3.3v and power on esp12
Use 1k res between VCC and CHPD
Use cap between esp gnd and vcc
connect Hygrometer Analogic pin to ESP A0
connect Relay1 to GPIO 3
connect Relay2 to GPIO 5
connect Relay3 to GPIO 4
connect Relay4 to GPIO 0
connect Relay5 to GPIO 10
connect Relay6 to GPIO 13
connect Relay7 to GPIO 14
connect Relay8 to GPIO 16
Connect 12v to any single input of relay board
connect output of any single relay to valve +

That's all folks!!!

Know bugs:

Programs from 23.59 to 00.00 doesn't work
Program with overlapping valves pheraps can't work well in the minute of ending active program
