This is a smart farming implementation I made for a small scale farm in Texas
This project is in progress, please wait for more updates as they become available
The hardware is seperated into nodes, each containing their own implementation and schematics.
A Raspberry Pi 0w is used for the database and server
A Heltec ESP32-LoRa controls the LoRaWan Gateway
The NodeMCU ESP8266 handles the Air quality and weather status node.
An Arduino Nano with an AI-Thinker RA-02 (SX1278 433Mhz communication module) is used for field soil monitoring, and automated irrigation as well as handling its own solar module implementation.
A Router is used to handle MQTT messaging as well as clients.
Server:
Node.js
mqtt
express
sockets.io
ejs
jquery
Database:
RethinkDB
Communication layer:
MQTT (802.11)
LoRa (433Mhz)
A ~.02 acre plot of land with a fence was prepared by first cutting down any vegetation, tilling, and creating rows for the crop.
A Drip irrigation system was added so the system can water only where necessary, conserving water and energy.
A Corn seedling can be seen emerging from the soil with its respective dripper
