c# 温湿度传感器开发用的是tcp或者udp通信，这里介绍udp用法

代码就不上传了，想要可以私聊我，在开发过程中，不可避免出现问题，需要先调试走通，我是用的

设备是用的这款

新建一个工程，直接发送请求数据命令

 /// <summary>        /// 发送信息        /// </summary>        /// <param name="obj"></param>        private void SendMessage(object obj)        {            string message = (string)obj;            //00 B0 D0 2A B7 3C FF 03 00 00 00 06            byte[] mybyte = new byte[12];            mybyte[0] = 0x00;            mybyte[1] = 0xB0;            mybyte[2] = 0xD0;            mybyte[3] = 0x2A;            mybyte[4] = 0xB7;            mybyte[5] = 0x3C;            mybyte[6] = 0xFF;            mybyte[7] = 0x03;            mybyte[8] = 0x00;            mybyte[9] = 0x00;            mybyte[10] = 0x00;            mybyte[11] = 0x06;            IPEndPoint remoteIpep = new IPEndPoint(                IPAddress.Parse(ConfigurationManager.AppSettings["IP"]), Int32.Parse(ConfigurationManager.AppSettings["Port"])); // 发送到的IP地址和目标端口号            udpcSend.Send(mybyte, mybyte.Length, remoteIpep);            udpcSend.Close();        }        private void sendMessage() {            // 实名发送            try            {                IPEndPoint localIpep = new IPEndPoint(             IPAddress.Parse(ip), Int32.Parse(ConfigurationManager.AppSettings["CurrentPort"])); // 本机IP，本机端口号                udpcSend = new UdpClient(localIpep);                Thread thrSend = new Thread(SendMessage);                thrSend.Start();            } catch {            }                   }

发送成功后，传感器会反馈给你结果，然后就是接收数据
