Managers/MqttClientManager.cs - HMAC-SHA1自实现

4. SHT30 温湿度传感器 (Drivers/Sht30Sensor.cs)
纯I2C通信实现，不依赖外部传感器库。
Drivers/Sht30Sensor.cs - 核心读取
|----------------------------------------------------------------------------|
| public class Sht30Sensor : IDisposable |
| { |
| private I2cDevice _i2cDevice; |
| private const byte CMD_MEASURE_HIGH_REP = 0x2C; // 单次测量(高重复性) |
| private const byte CMD_MEASURE_HIGH_REP_2 = 0x06; |
| |
| public Sht30Sensor() |
| { |
| // 配置I2C引脚：SDA=GPIO17, SCL=GPIO18 |
| Configuration.SetPinFunction(17, DeviceFunction.I2C1_DATA); |
| Configuration.SetPinFunction(18, DeviceFunction.I2C1_CLOCK); |
| |
| var settings = new I2cConnectionSettings(1, 0x44); // BusId=1, 地址0x44 |
| _i2cDevice = I2cDevice.Create(settings); |
| } |
| |
| public Sht30Data ReadMeasurement() |
| { |
| // 1. 发送测量命令 |
| _i2cDevice.Write(new byte[] { 0x2C, 0x06 }); |
| |
| // 2. 等待测量完成（高重复性≈15ms） |
| Thread.Sleep(20); |
| |
| // 3. 读取6字节：[温度高, 温度低, CRC, 湿度高, 湿度低, CRC] |
| byte[] buf = new byte[6]; |
| _i2cDevice.Read(buf); |
| |
| // 4. 计算公式 |
| int rawT = (buf[0] << 8) | buf[1]; |
| int rawH = (buf[3] << 8) | buf[4]; |
| |
| double temperature = -45.0 + (175.0 * rawT / 65535.0); |
| double humidity = 100.0 * rawH / 65535.0; |
| |
| // 5. CRC-8校验（多项式0x31） |
| CheckCRC(buf[0], buf[1], buf[2]); |
| CheckCRC(buf[3], buf[4], buf[5]); |
| |
| return new Sht30Data { Temperature = temperature, Humidity = humidity }; |
| } |
| |
| // CRC-8校验 (x^8 + x^5 + x^4 + 1) |
| private bool CheckCRC(byte d1, byte d2, byte crc) |
| { |
| byte val = 0xFF; |
| val ^= d1; |
| for (int i = 0; i < 8; i++) |
| val = (byte)((val & 0x80) != 0 ? (val << 1) ^ 0x31 : val << 1); |
| val ^= d2; |
| for (int i = 0; i < 8; i++) |
| val = (byte)((val & 0x80) != 0 ? (val << 1) ^ 0x31 : val << 1); |
| return val == crc; |
| } |
| } |
温度公式 ：T = -45 + 175 × (raw / 65535) °C
湿度公式 ：RH = 100 × (raw / 65535) %
5. 数据采集与上传 (Program.cs 主循环)
Program.cs - UploadDataToCloud()
|------------------------------------------------------------------------------|
| private static void UploadDataToCloud() |
| { |
| if (_mqttClientManager == null || !_mqttClientManager.IsConnected) return; |
| |
| // 采集数据 |
| double temperature = 0, humidity = 0; |
| bool relayState = false; |
| |
| if (_sht30Sensor != null) |
| { |
| var data = _sht30Sensor.ReadMeasurement(); |
| if (data != null) |
| { |
| // 四舍五入保留一位小数 |
| temperature = (int)(data.Temperature * 10 + 0.5) / 10.0; |
| humidity = (int)(data.Humidity * 10 + 0.5) / 10.0; |
| } |
| } |
| |
| if (_relayDriver != null) |
| relayState = _relayDriver.GetState(0); |
| |
| // 构建YFLink属性（属性ID需与云端物模型一致） |
| var properties = new Hashtable |
| { |
| { "H", humidity }, // 湿度 |
| { "T", temperature }, // 温度 |
| { "I1", 0 }, // 开关量输入1 |
| { "I2", 0 }, // 开关量输入2 |
| { "Q1", relayState ? 1 : 0 } // 继电器输出1 |
| }; |
| |
| _mqttClientManager.PublishProperties(properties); |
| } |
6. 数据模型 (Models/DeviceModels.cs)
|------------------------------------------------------|
| namespace YeFanIoTTest.Models |
| { |
| public class DeviceConfig |
| { |
| public string ProjectID { get; set; } // 项目ID |
| public string ProductID { get; set; } // 产品ID |
| public string DeviceID { get; set; } // 设备ID |
| public string DeviceKey { get; set; } // 设备密钥(32位) |
| public string MqttServer { get; set; } // MQTT服务器 |
| public int MqttPort { get; set; } // MQTT端口 |
| } |
| |
| public class WifiConfig |
| { |
| public string SSID { get; set; } |
| public string Password { get; set; } |
| } |
| |
| public class SensorData |
| { |
| public double Temperature { get; set; } |
| public double Humidity { get; set; } |
| public DateTime Timestamp { get; set; } |
| } |
| } |
7. 枚举定义 (Enums/Enums.cs)
|----------------------------------------------------------------------------|
| namespace YeFanIoTTest.Enums |
| { |
| public enum DeviceState { Initializing, CheckingConfig, APConfiguring, |
| ConnectingWifi, ConnectingCloud, NormalRunning, Error } |
| public enum NetworkStatus { Connecting, Connected, Disconnected, Error } |
| public enum ConfigStatus { Configuring, Success, Failed, Normal } |
| public enum LedBlinkMode { Off, On, SlowBlink, FastBlink } |
| public enum EventType { Info = 0, Warning = 1, Fault = 2 } |
| public enum ServiceType { Command = 0, Parameter = 1 } |
| } |
8. 按钮与配网交互
Program.cs - 按钮事件处理
|----------------------------------------------------------|
| _buttonDriver.OnButtonEvent += (sender, e) => |
| { |
| if (e.EventType == ButtonEventType.ShortPress) |
| { |
| // 短按：切换继电器 |
| _relayDriver.Toggle(0); |
| } |
| else if (e.EventType == ButtonEventType.LongPress) |
| { |
| // 长按(3秒)：启动AP配网模式 |
| // SSID: YF3300_ESP32S3 密码: yf123456 |
| // 配网页面: http://192.168.4.1 |
| new Thread(() => StartAPConfigMode()).Start(); |
| } |
| }; |
| |
| // 配网完成回调 |
| _apConfigManager.OnConfigCompleted += (sender, e) => |
| { |
| if (e.Success) |
| { |
| _ledManager.SetNetworkStatus(NetworkStatus.Connected); |
| InitializeNtpTime(); // 配网成功后同步时间 |
| } |
| }; |
