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
