LoRa Based Smart Agriculture Monitoring System

DOWNLOAD ABSTRACT

AIM:

Design and Development of LoRa based smart agriculture monitoring system.

PURPOSE:

Agriculture sectors are primary resource of any country. People food supply chain depends on agriculture production and maintenance. Bringing technology into agriculture will effect on production. Here we want to develop smart agriculture system that can tell few parameters and controls water pump automatically. We choose LoRa technology because of its own benefits like low power and long range. Proposed project title is LoRa based smart agriculture monitoring system using Arduino and ESP32 nodemcu.

DESCRIPTION:

This project has two sections, one is transmitter which is at farm area which has Arduino and sensors along with LoRa Module (SX1278). Soil moisture sensor, LM35, LDR, Relay pump connected to Arduino digital and analog pins respectively. Receiver part has ESP32 nodemcu connected with LoRa (SX1278) through SPI port. Receiver part placed at farmer house. On both the sides LCD connected to digital pins.

WORKING:

Arduino continuously reads sensors data and displaying on LCD. Based on Soil moisture we and dry conditions water pump will be ON with the help of relay. LM35 can read atmospheric temperature and LDR can read light intensity. Soil moisture sensor is resistive type which can detect soil wet and dry conditions. All these sensors data will transfer to receiver side LoRa module and displaying on LCD display. At receiver side ESP32 nodemcu updates this information to IOT cloud server. Receiver side system will be places at farmer house or required area.
