ESP8266 temperature / humidity transmitter over MQTT
this repository contains a simple DHT22 temperature and humidity transmitter over MQTT.
This project has been developed using PlatformIO. In order to run project a private_settings.h should be provided inside src folder. The private_setting has the following structure:
const char* ssid = "Wifi_SSID"; const char* password = "Wifi_password"; const char* mqtt_server = "MQTT host"; const char* clientID = "MQTT client ID"; const char* temperatureTopic = "topic/for/temperature"; const char* humidityTopic = "topic/for/humidity"; const char * token ="MQTT token String"; const int32 refreshTime = 300000; //Time to refresh in seconds
I promise to publish more information about the wiring in the next few days :)
