Example: data lecture & publish #include #include #include // PIN POSITIONS #define TEMP_HUMI_PIN 24 #define SOUND_SENSOR 6 #define LIGHT_SENSOR 2 #define ROOM_ID 1 DHT dht(TEMP_HUMI_PIN, DHT22); WiFiClient wifiClient; PubSubClient client(server, 16301, callback, wifiClient); char temp_buffer[256]; char humidity_buffer[256]; void setup() { // Setting up ... dht.begin(); } void loop() { }

Example: data lecture & publish void loop() { // read values from sensors & pubish to mqtt _temperature = dht.readTemperature(); _humidity = dht.readHumidity(); sprintf(temp_buffer, "{\"value\": %d,\"room_id\": %d}", _temperature, ROOM_ID); sprintf(humidity_buffer, "{\"value\": %d,\"room_id\": %d}", _humidity, ROOM_ID); if (client.publish("temp", temp_buffer) && client.publish("humidity", humidity_buffer){ log("Data published succeeded!"); } else { log("Data publish failed"); } delay(5000); } void log() {}
