Hi,

I want to send data from my wemos d1 to carriots. The data is from a MPU6050. The problem is that in my carriots appears {"moisture":"3"}.

This is the code:

// MPU-6050 Short Example Sketch
// By Arduino User JohnChi
// August 17, 2014
// Public Domain
#include<Wire.h>
const int MPU_addr=0x68;  // I2C address of the MPU-6050
int16_t AcX,AcY,AcZ,Tmp,GyX,GyY,GyZ;
#include "ESP8266WiFi.h"
const char* ssid     = "---";
const char* password = "---";
const char* server = "api.carriots.com";
// Replace with your Carriots apikey
const String APIKEY = "---";
const String DEVICE = "---"; // your deviceID
WiFiClient client;
 
int val = 0;
 
void setup() {
  Wire.begin();
  Wire.beginTransmission(MPU_addr);
  Wire.write(0x6B);  // PWR_MGMT_1 register
  Wire.write(0);     // set to zero (wakes up the MPU-6050)
  Wire.endTransmission(true);
  Serial.begin(9600);
  Serial.begin(115200);
  delay(1000);
  // start wifi
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
    
  }
 
  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}
// Send data to  Carriot
 
void sendStream()
{
  Wire.beginTransmission(MPU_addr);
  Wire.write(0x3B);  // starting with register 0x3B (ACCEL_XOUT_H)
  Wire.endTransmission(false);
  Wire.requestFrom(MPU_addr,14,true);  // request a total of 14 registers
  AcX=Wire.read()<<8|Wire.read();  // 0x3B (ACCEL_XOUT_H) & 0x3C (ACCEL_XOUT_L)    
  AcY=Wire.read()<<8|Wire.read();  // 0x3D (ACCEL_YOUT_H) & 0x3E (ACCEL_YOUT_L)
  AcZ=Wire.read()<<8|Wire.read();  // 0x3F (ACCEL_ZOUT_H) & 0x40 (ACCEL_ZOUT_L)
  Tmp=Wire.read()<<8|Wire.read();  // 0x41 (TEMP_OUT_H) & 0x42 (TEMP_OUT_L)
  GyX=Wire.read()<<8|Wire.read();  // 0x43 (GYRO_XOUT_H) & 0x44 (GYRO_XOUT_L)
  GyY=Wire.read()<<8|Wire.read();  // 0x45 (GYRO_YOUT_H) & 0x46 (GYRO_YOUT_L)
  GyZ=Wire.read()<<8|Wire.read();  // 0x47 (GYRO_ZOUT_H) & 0x48 (GYRO_ZOUT_L)
  Serial.print("AcX = "); Serial.print(AcX);
  Serial.print(" | AcY = "); Serial.print(AcY);
  Serial.print(" | AcZ = "); Serial.print(AcZ);
  Serial.print(" | Tmp = "); Serial.print(Tmp/340.00+36.53);  //equation for temperature in degrees C from datasheet
  Serial.print(" | GyX = "); Serial.print(GyX);
  Serial.print(" | GyY = "); Serial.print(GyY);
  Serial.print(" | GyZ = "); Serial.println(GyZ);
  delay(333);
  //const int httpPort = 80;
  if (client.connect(server, 80)) {   // If there's a successful connection
    Serial.println(F("connected"));
 
    // construct the data json
    String json = "{\"protocol\":\"v2\",\"device\":\"" + DEVICE + "\",\"at\":\"now\",\"data\":{\"moisture\":\"" + val + "\"}}";
 
    // Make an HTTP request
    client.println("POST /streams HTTP/1.1");
    client.println("Host: api.carriots.com");
    client.println("Accept: application/json");
    client.println("User-Agent: Arduino-Carriots");
    client.println("Content-Type: application/json");
    client.print("carriots.apikey: ");
    client.println(APIKEY);
    client.print("Content-Length: ");
    int thisLength = json.length();
    client.println(thisLength);
    client.println("Connection: close");
    client.println();
    client.println(json);
  }
  else {
    // If server connection failed:
    Serial.println(F("connection failed"));
  }
}
void loop() {
  val = analogRead(A0);
  Serial.println(val);
  Serial.println(F("Send Data"));
  sendStream();
  delay(30000);
}
 
Thank you!

Hi Albersase

 

What is the problem of sending {"moisture":"3"}? Do you want to send any other info?

 

 

Regards!
