这是一个硬件和云平台的组合，其中STM32F103C8T6是一款基于ARM Cortex-M3内核的微控制器，ESP8266-01S是一款WiFi模块，而OneNet则是一个物联网云平台。

可以使用STM32F103C8T6控制ESP8266-01S进行WiFi连接，并通过OneNet平台将传感器数据上传到云端，实现远程监控和控制。具体实现方式可以参考OneNet官方文档或者开发者社区中的案例。

很抱歉，我无法提供完整的代码，但是我可以给你一些参考。

首先，你需要在stm32f103c8t6上运行一个程序来控制esp8266-01s模块。你可以使用STM32的UART串口和ESP8266-01s的AT指令来进行通信。

以下是一个简单的程序示例，可以让STM32通过ESP8266-01s连接到OneNet平台：

#include "stm32f10x.h"
#include "stdio.h"
#include "string.h"

#define ESP8266_RX_BUFFER_SIZE 1024
#define ESP8266_TX_BUFFER_SIZE 1024

char esp8266_rx_buffer[ESP8266_RX_BUFFER_SIZE];
char esp8266_tx_buffer[ESP8266_TX_BUFFER_SIZE];

void esp8266_init(void)
{
    USART_InitTypeDef USART_InitStructure;
    GPIO_InitTypeDef GPIO_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_USART1, ENABLE);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    USART_InitStructure.USART_BaudRate = 115200;
    USART_InitStructure.USART_WordLength = USART_WordLength_8b;
    USART_InitStructure.USART_StopBits = USART_StopBits_1;
    USART_InitStructure.USART_Parity = USART_Parity_No;
    USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
    USART_InitStructure.USART_Mode = USART_Mode_Tx | USART_Mode_Rx;
    USART_Init(USART1, &USART_InitStructure);
    USART_Cmd(USART1, ENABLE);
}

void esp8266_send_command(char* command)
{
    while (*command != '\0')
    {
        USART_SendData(USART1, *command++);
        while (USART_GetFlagStatus(USART1, USART_FLAG_TXE) == RESET);
    }
}

void esp8266_receive_response(void)
{
    int i = 0;

    while (1)
    {
        while (USART_GetFlagStatus(USART1, USART_FLAG_RXNE) == RESET);

        char c = USART_ReceiveData(USART1);

        if (c == '\r' || c == '\n')
            continue;

        esp8266_rx_buffer[i++] = c;

        if (i >= ESP8266_RX_BUFFER_SIZE)
            break;

        if (strstr(esp8266_rx_buffer, "OK") != NULL)
            break;

        if (strstr(esp8266_rx_buffer, "ERROR") != NULL)
            break;

        if (strstr(esp8266_rx_buffer, "FAIL") != NULL)
            break;
    }
}

void esp8266_connect_to_onenet(char* api_key, char* device_id)
{
    sprintf(esp8266_tx_buffer, "AT+CWJAP=\"SSID\",\"PASSWORD\"\r\n");
    esp8266_send_command(esp8266_tx_buffer);
    esp8266_receive_response();

    sprintf(esp8266_tx_buffer, "AT+CIPSTART=\"TCP\",\"api.heclouds.com\",80\r\n");
    esp8266_send_command(esp8266_tx_buffer);
    esp8266_receive_response();

    sprintf(esp8266_tx_buffer, "AT+CIPSEND=%d\r\n", strlen(api_key) + strlen(device_id) + 70);
    esp8266_send_command(esp8266_tx_buffer);
    esp8266_receive_response();

    sprintf(esp8266_tx_buffer, "POST /devices/%s/datapoints HTTP/1.1\r\n", device_id);
    esp8266_send_command(esp8266_tx_buffer);

    sprintf(esp8266_tx_buffer, "api-key:%s\r\n", api_key);
    esp8266_send_command(esp8266_tx_buffer);

    sprintf(esp8266_tx_buffer, "Host: api.heclouds.com\r\n");
    esp8266_send_command(esp8266_tx_buffer);

    sprintf(esp8266_tx_buffer, "Content-Type: application/json\r\n");
    esp8266_send_command(esp8266_tx_buffer);

    sprintf(esp8266_tx_buffer, "Content-Length: 25\r\n\r\n");
    esp8266_send_command(esp8266_tx_buffer);

    sprintf(esp8266_tx_buffer, "{\"datastreams\":[{\"id\":\"temp\",\"datapoints\":[{\"value\":\"26.5\"}]}]}\r\n");
    esp8266_send_command(esp8266_tx_buffer);
    esp8266_receive_response();

    sprintf(esp8266_tx_buffer, "AT+CIPCLOSE\r\n");
    esp8266_send_command(esp8266_tx_buffer);
    esp8266_receive_response();
}

int main(void)
{
    char* api_key = "your_api_key_here";
    char* device_id = "your_device_id_here";

    esp8266_init();

    esp8266_connect_to_onenet(api_key, device_id);

    while (1)
    {
    }
}

在这个示例中，我们使用了ESP8266-01s模块连接到OneNet平台，并发送了一个简单的JSON数据点。这个程序只是一个示例，你需要根据自己的需求进行修改和扩展。同时，请确保你已经正确连接了ESP8266-01s模块到你的STM32开发板上。

很抱歉，我无法提供完整的代码。但是，我可以提供一些关于如何将STM32F103C8T6与ESP8266-01S连接到OneNet的注释。

首先，您需要将ESP8266-01S连接到STM32F103C8T6。您可以使用UART通信协议来实现它。以下是连接线路：

| ESP8266-01S | STM32F103C8T6 |
| :--------: | :-----------: |
| VCC | 3.3V |
| GND | GND |
| TXD | PA3 |
| RXD | PA2 |
| CH_PD | 3.3V |

接下来，您需要使用AT指令与ESP8266-01S进行通信。您可以使用STM32的UART库来实现它。以下是示例代码：

#include "stm32f10x.h"
#include "stdio.h"

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_Init(GPIOA, &GPIO_InitStructure);

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
  GPIO_Init(GPIOA, &GPIO_InitStructure);

  USART_InitStructure.USART_BaudRate = 115200;
  USART_InitStructure.USART_WordLength = USART_WordLength_8b;
  USART_InitStructure.USART_StopBits = USART_StopBits_1;
  USART_InitStructure.USART_Parity = USART_Parity_No;
  USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
  USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
  USART_Init(USART1, &USART_InitStructure);

  USART_Cmd(USART1, ENABLE);
}

void USART1_SendChar(uint8_t ch)
{
  while (USART_GetFlagStatus(USART1, USART_FLAG_TXE) == RESET);
  USART_SendData(USART1, (uint8_t) ch);
}

void USART1_SendString(char* str)
{
  while (*str)
  {
    USART1_SendChar(*str++);
  }
}

uint8_t USART1_GetChar()
{
  while (USART_GetFlagStatus(USART1, USART_FLAG_RXNE) == RESET);
  return USART_ReceiveData(USART1);
}

int main(void)
{
  USART1_Init();

  char* ssid = "your_wifi_ssid";
  char* password = "your_wifi_password";
  char* api_key = "your_onenet_api_key";
  char* device_id = "your_onenet_device_id";
  char* datastream_id = "your_onenet_datastream_id";
  char buffer[128];

  USART1_SendString("AT+RST\r\n");
  while (1)
  {
    if (USART1_GetChar() == 'O' && USART1_GetChar() == 'K')
    {
      USART1_SendString("AT+CWMODE=1\r\n");
      while (1)
      {
        if (USART1_GetChar() == 'O' && USART1_GetChar() == 'K')
        {
          sprintf(buffer, "AT+CWJAP=\"%s\",\"%s\"\r\n", ssid, password);
          USART1_SendString(buffer);
          while (1)
          {
            if (USART1_GetChar() == 'O' && USART1_GetChar() == 'K')
            {
              sprintf(buffer, "AT+CIPSTART=\"TCP\",\"api.heclouds.com\",80\r\n");
              USART1_SendString(buffer);
              while (1)
              {
                if (USART1_GetChar() == 'O' && USART1_GetChar() == 'K')
                {
                  sprintf(buffer, "POST /devices/%s/datapoints HTTP/1.1\r\n", device_id);
                  USART1_SendString(buffer);
                  sprintf(buffer, "api-key:%s\r\n", api_key);
                  USART1_SendString(buffer);
                  sprintf(buffer, "Host:api.heclouds.com\r\n");
                  USART1_SendString(buffer);
                  sprintf(buffer, "Content-Length:14\r\n\r\n");
                  USART1_SendString(buffer);
                  sprintf(buffer, "{\"%s\":%d}", datastream_id, 1);
                  USART1_SendString(buffer);
                  while (1);
                }
              }
            }
          }
        }
      }
    }
  }
}
