Configuring Linux systems to support the development of smart agriculture and agricultural automation

With the development of science and technology, smart agriculture and agricultural automation have become important directions in modern agriculture. As an open source operating system, Linux has a wide range of applications in the fields of smart agriculture and agricultural automation. This article will introduce how to configure a Linux system to support smart agriculture and agricultural automation development, and provide some related code examples.

1. Install the Linux system
First, we need to choose a suitable Linux distribution for installation. Common Linux distributions include Ubuntu, CentOS, etc. You can choose the appropriate version according to your own needs.

2. Install necessary software and tools
To develop smart agriculture and agricultural automation on a Linux system, you need to install some necessary software and tools, such as Python, Node.js, etc. You can use package management tools (such as APT, Yum, etc.) to install these software.

Taking the Ubuntu system as an example, you can use the following commands to install Python and Node.js:

$ sudo apt-get update
$ sudo apt-get install python nodejs

3. Install sensors and motor control modules
Various sensors and motor control modules are often used in the development of smart agriculture and agricultural automation, such as temperature and humidity sensors, light sensors, water level sensors, and motor control modules. Select appropriate sensors and motor control modules for installation based on specific needs.

On Linux systems, we can control sensors and motor control modules through GPIO (General Purpose Input and Output). GPIO is a general-purpose interface used to transmit digital signals between computers and external devices. For specific GPIO pin numbers and usage methods, please refer to relevant documents.

4. Writing smart agriculture and agricultural automation programs
After configuring the Linux system and installing the required software and hardware, we can start writing smart agriculture and agricultural automation programs. The following is a simple sample code for reading the data of the temperature and humidity sensor and controlling the motor control module:

import time
import Adafruit_DHT
import RPi.GPIO as GPIO

sensor = Adafruit_DHT.DHT11
pin = 4
motor_pin = 17

GPIO.setmode(GPIO.BCM)
GPIO.setup(motor_pin, GPIO.OUT)

while True:
    humidity, temperature = Adafruit_DHT.read_retry(sensor, pin)
    if humidity is not None and temperature is not None:
        print('Temperature: {0:0.1f} °C'.format(temperature))
        print('Humidity: {0:0.1f} %'.format(humidity))
        if temperature > 25:
            GPIO.output(motor_pin, GPIO.HIGH)
        else:
            GPIO.output(motor_pin, GPIO.LOW)
    else:
        print('Failed to read sensor data')

    time.sleep(2)

The above code uses the Adafruit_DHT library to read the data of the temperature and humidity sensor, and uses the RPi.GPIO library to control the motor control module. Depending on the actual situation, you may need to modify the pin number and sensor type.

5. Use cloud platform for remote monitoring and control
In order to achieve remote monitoring and control, a cloud platform can be used to build an intelligent agriculture and agricultural automation system. Common cloud platforms include AWS, Azure, etc. You can choose the appropriate platform according to actual needs.

On the cloud platform, various transmission protocols (such as MQTT, HTTP, etc.) can be used to transmit sensor data to the cloud, and real-time monitoring and remote control can be performed through web pages or mobile apps.

Summary
This article describes how to configure a Linux system to support smart agriculture and agricultural automation development, and provides a simple code example. I hope this article can provide some reference and reference for the majority of agricultural technology enthusiasts and developers. By rationally utilizing Linux systems and related tools, we can better promote the development of smart agriculture and agricultural automation.
