Design of Mobile Agricultural Data Collection Equipment Based on Arduino

摘要

The development from traditional agriculture to intelligent agriculture needs to be driven by data. Acquiring agricultural environmental data through sensors and using advanced means such as wireless data transmission and IoT technology make agricultural data collection more refined and intelligent. In this paper, we design a prototype of Arduino-based mobile agricultural data collection device. The ESP8266-Node MCU development board is connected to a DC stepper motor driver board, a tri-color LED module and a buzzer. Using the driver module to drive two DC motors, the Arduino Nano development board is connected to a temperature and humidity sensor, a photoresistor sensor and a gas sensor. After compiling in the Arduino IDE environment and networking using the WiFi module of the ESP8266-NodeMCU development board, the device is controlled through a software application to receive and view the collected data. The four SG90 servos are controlled by connecting the breadboard power module and the Bluetooth module through the Arduino UNO R3 development board. After the Bluetooth connection, the four servos are controlled by the software application to achieve the robotic arm grasping function. The test experiment results show that the device runs smoothly, the light illumination, alarm and robotic arm grasping functions can be realized, and the movable collection of specific data about the environment where the crops are located, such as temperature, humidity, light level and gas can be smoothly realized, and the collected datas meet the objective regular changes.
