Arduino ESP8266 Internet of things

IoT applied in Agriculture with Arduino

Connected objects have applications in many sectors, and agriculture is one of the most benefiting from the benefits of the Internet of Things.

Purpose of this project:

This project describes the application of IoT (Internet of Things) in agriculture. In this environment we take measurements of the humidity of the soil of a plant.

Monitoring of the parameter around this process (information provided by the soil sensor) is done using open source tools and resources such as Arduino and ThingSpeak.

We read the sensor data in real time on the internet through a web page and also on the graphs in ThingSpeak.

This work is done using a microcontroller (Arduino) connected to an ESP8266 module which will send all information via WIFI concerning the environment of our plant, to ThingSpeak.

Necessary components

  • Arduino
  • Soil moisture sensor

  • ESP8266 wifi
  • Connecting wires

  • Test plate

  • Wifi network

Mounting :

To perform the assembly, you can connect:

for the soil sensor:

  • pin S to pin A0 of the Arduino board

  • the pin (+) to the 3.3V pin of the Arduino board

  • the pin (-) to the GND pin of the Arduino board

For ESP8266 module:

  • The RX pin to pin 4 of the Arduino board

  • The TX pin to pin 3 of the Arduino board

  • The GND pin to the GND of the Arduino board

  • The two pins 3V3 and EN to the 5V pin of the power supply module

  • The RST pin to pin 8 of the Arduino board

The soil moisture values sent by the Arduino board to the thinkspeak.com site
