2.1. Requirements Analysis and Design Goals
- (1)
- Pest information collection module (PICM): When pests approach the metal mesh, the metal mesh will release high-voltage pulses, and the electrocuted insect corpses will fall into the insect storage box. The sound sensor records the number of insects killed by detecting the level changes.
- (2)
- Environmental information collection module (EICM): Serving as the core platform for collecting environmental data and implementing eco-friendly pest control. It integrates various sensors to monitor conditions, e.g., air temperature and humidity, light intensity, soil temperature and moisture, pH levels, soil conductivity, and the concentrations of nitrogen, phosphorus, and potassium (NPK). This integration supports seamless environmental data acquisition and pest control, contributing to optimal crop growth conditions.
- (3)
- Multi-view image collection module (MICM): This module is equipped with three cameras positioned to capture images from the left, right, and top views. It enables the collection of full-cycle images of the crop growth process and high-frequency images detailing crop morphological characteristics and growth status. The multi-angle approach improves the accuracy of monitoring the crop height, leaf color, and pest and disease conditions.
- (4)
- Visualization software: LabVIEW software (LabVIEW 2022 32-bit) is used to display the collected data in the form of continuous statistical graphs, visually illustrating trends in the air temperature, humidity, light intensity, and soil parameters. This comprehensive visualization aids in monitoring and analyzing fluctuations in crop growth data throughout the growth process.

4.1. Environmental Information Collection Module Program Design
4.1.1. DHT11 Temperature and Humidity Sensor
- (1)
- Initialization: The driver initializes the sensor by setting the GPIO pin mode and communication rate. The ESP32-S3 sends a start signal, pulls down the data line low for over 18 ms, and then pulls it high for 20~40 μs, waiting for the DHT11 to respond.
- (2)
- Response signal: The DHT11 responds to the host’s start signal by pulling the data line down for about 80 μs, and then pulling it up for about 80 μs. Then, the DHT11 sends 40 bits of binary data, where a high level represents a one and a low level represents a zero.
- (3)
- Data parsing: The ESP32-S3 parses the received data packet, including splitting the data segmentation, checksum verification, format conversion, and calculation of the temperature and humidity values. We defined the data packet format as shown in Figure 11, where 16 bits represent the temperature, 16 bits represent the humidity, and the last 8 bits are used for the checksum. The checksum is calculated by summing the first 32 bits and comparing it with the last 8 bits. If the checksum fails, the sensor retransmits the data.
- (4)
- Data output: Once the checksum is verified as correct, the sensor releases the bus. The ESP32-S3 then converts and outputs the temperature and humidity data to the upper computer display.
4.1.2. DS18B20 Temperature Sensor
- (1)
- Reset signal: The ESP32-S3 sends a reset signal to the DS18B20, pulls the data line down for over 480 μs and then pulls it up for about 60 μs. The system waits for the response from the DS18B20. If the response is successful, the DS18B20 pulls the data line low for about 60 μs, and then returns to the high-level state (about 480 μs) at the time of power-on reset.
- (2)
- Send command: The ESP32-S3 sends a “Read ROM” or “Skip ROM” command, prompting the DS18B20 to return its unique ROM code for identification.
- (3)
- Temperature conversion: The ESP32-S3 sends a temperature conversion command, pulling the data line low for at least 1 μs, and then pulling it high again. The DS18B20 starts the temperature conversion and stores the converted data in the internal memory at address 0x44.
- (4)
- Read data: After the temperature conversion is completed, the ESP32-S3 sends a read command that lasts at least 1 μs. Then, the DS18B20 returns 9 bytes of temperature data, where each data bit lasts about 60 μs, and a high level represents one and a low level represents zero.
- (5)
- Data parsing: The ESP32-S3 parses the returned raw temperature data and converts it into standard Celsius format.
- (6)
- CRC checksum: The ESP32-S3 verifies the CRC checksum. If the checksum is correct, it outputs the temperature value to the upper computer for display and closes the program to release the bus.
4.1.3. GY-39 Light Intensity Sensor
- (1)
- Initialization: The I2C address of the GY-39 sensor is defined. The setup function initializes the serial communication and the IIC bus, configuring the ESP32-S3 as the master device.
- (2)
- Send read command: The ESP32-S3 sends a command to read light intensity data from the GY-39, specifying the address of the data to be read. The Wire.requestFrom() function is utilized to request the 2-byte raw light intensity raw data packet.
- (3)
- Receive and parse the data: After receiving the read command, the GY-39 sends a response signal and sends the data back to the ESP32-S3. The Wire.read() function is used to parse the raw data packet byte by byte, combining the high 8 bits and low 8 bits to form the actual 16-bit sensor data through bitwise operations.
- (4)
- Data output: The parsed data are processed and output through the serial port.
4.1.4. FC-04 Sound Sensor
- (1)
- Set I/O Pins: The I/O pins of the FC-04 are configured to output mode. The integrated level comparator within the FC-04 outputs a high-level signal upon detecting surrounding insecticidal sounds.
- (2)
- Read data: The ESP32-S3 continuously monitors the level changes in the I/O pins and records these variations.
- (3)
- Data Processing and Transmission: The system filters and processes the collected insecticidal sound data. The processed data are transmitted to the upper computer through the serial port or other communication methods for user access.
4.1.5. Kenqi-RS485 Soil Sensor
- (1)
- Address code: Indicates the address of the sensor, usually represented as an 8-bit binary number.
- (2)
- Function code: Specifies the type of operation for the communication, also represented as an 8-bit binary number.
- (3)
- Data area: Contains the request or response data. The length of this section depends on the type of communication operation.
- (4)
- Error check: Verifies the integrity of the communication frame using a 16-bit cyclic redundancy check (CRC) code.
