i am using arduino mega and esp 01.i am getting reading on serial monitor.but thingspeak shows 0 for 5 sensors data fields.where is the problem in this code please help me. Esp 01 code- #include "ThingSpeak.h" #include <ESP8266WiFi.h> char ssid[] = "xxxxxxx"; // SSID here char pass[] = "xxxxxxxx"; // Passowrd here unsigned long Channel_ID = xxxxxx; // Channel ID const char * myWriteAPIKey = "xxxxxxxx"; // Write API key const int Field_Number_1 = 1; const int Field_Number_2 = 2; const int Field_Number_3 = 3; const int Field_Number_4 = 4; const int Field_Number_5 = 5; String value = ""; int value_1 = 0, value_2 = 0, value_3 = 0, value_4 = 0, value_5 = 0; WiFiClient client; void setup() { Serial.begin(115200); WiFi.mode(WIFI_STA); ThingSpeak.begin(client); internet(); } void loop() { internet(); if (Serial.available() > 0) { delay(100); while (Serial.available() > 0) { value = Serial.readString(); if (value[0] == '*') { if (value[11] == '#') { value_1 = ((value[1] - 0x30) * 10 + (value[2] - 0x30)); value_2 = ((value[3] - 0x30) * 10 + (value[4] - 0x30)); value_3 = ((value[5] - 0x30) * 10 + (value[6] - 0x30)); value_4 = ((value[7] - 0x30) * 10 + (value[8] - 0x30)); value_5 = ((value[9] - 0x30) * 10 + (value[10] - 0x30)); } } } } upload(); } void internet() { if (WiFi.status() != WL_CONNECTED) { while (WiFi.status() != WL_CONNECTED) { WiFi.begin(ssid, pass); delay(5000); } } } void upload() { ThingSpeak.writeField(Channel_ID, Field_Number_1, value_1, myWriteAPIKey); delay(15000); ThingSpeak.writeField(Channel_ID, Field_Number_2, value_2, myWriteAPIKey); delay(15000); ThingSpeak.writeField(Channel_ID, Field_Number_3, value_3, myWriteAPIKey); delay(15000); ThingSpeak.writeField(Channel_ID, Field_Number_4, value_4, myWriteAPIKey); delay(15000); ThingSpeak.writeField(Channel_ID, Field_Number_5, value_5, myWriteAPIKey); delay(15000); value = ""; } arduino code- #include <dht.h> #define soilWet 56 #define soilDry 50 const int LM35 = A0; // Soil Temperature pin // lowest and highest sensor readings (Rain Detection) const int sensorMin = 0; // sensor minimum const int sensorMax = 1024; // sensor maximum #define sensorPower 5 // Motor pin int obstaclePin = 10; // IR sensor pin 7 int hasObstacle = HIGH; // High means no obstacle const int trigger = 34; const int echo = 35; long T; float distanceCM; dht DHT; #define DHT11_PIN 30 int humi,temp; void setup(){ pinMode(sensorPower, OUTPUT); // Initially keep the Motor OFF digitalWrite(sensorPower, HIGH); pinMode(obstaclePin, INPUT); pinMode(trigger, OUTPUT); pinMode(echo, INPUT); Serial.begin(9600); } void loop() { int moisture = (100 - ((analogRead(A1)/1023.00)*100)); digitalWrite(trigger, LOW); delay(10); digitalWrite(trigger, HIGH); delayMicroseconds(10); digitalWrite(trigger, LOW); T = pulseIn(echo, HIGH); distanceCM = T * 0.034; distanceCM = distanceCM / 2; int ADC; float tempS; ADC = analogRead(LM35); tempS = (ADC * 4.88); tempS = (tempS / 10); int sensorReading = analogRead(A2); // Rain detection pin A2 int range = map(sensorReading, sensorMin, sensorMax, 0, 3); // Rain detection switch (range) { case 0: // Sensor getting wet Serial.println("Rain Status : ***Raining***"); break; case 1: // Sensor getting wet Serial.println("Rain Status : **Rain Warning**"); break; case 2: // Sensor dry - To shut this up delete the " Serial.println("Not Raining"); " below.
