Connected objects have applications in many sectors, and agriculture is one of the most benefiting from the benefits of the Internet of Things.
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 Micro: bit 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 carried out using a microcontroller (Micro: bit) connected to an ESP8266 module which will send all the information via WIFI concerning the environment of our plant, to ThingSpeak.
Soil moisture sensor
To perform the assembly, you can connect:
for the soil sensor:
pin S to pin P2 of the Micro:bit card
pin (+) to pin 3.3V of the Micro:bit card
the pin (-) to the GND pin of the Micro:bit card
For ESP8266 module:
The RX pin to P0 of the Micro: bit card Micro:bit card’s
TX pin to P1 The GND pin to the GND of the Micro:bit card
The two pins 3V3 and EN to the 5V pin of the power supply module
