Temperature dashboard using Arduino UNO, ESP8266 and MQTT

This sample application performs collection of temperature and humidity values produced by DHT22 sensor and further visualization on the real-time web dashboard. Collected data is pushed via MQTT to Thingsboard server for storage and visualization. Thingsboard is an open-source server-side platform that allows you to monitor and control IoT devices. It is free for both personal and commercial usage and you can deploy it anywhere. Once you complete this tutorial, you will see your sensor data on the following dashboard.”
