Here are some screenshots of the upgraded dashboard. And at the bottom is the full Node Red code.
Tag: MQTT
In previous two tutorials we learned how to set up ESP8266 with arduino IDE as temperature sensing node. Now we gonna look Node Red side of things and will create dashboard for displaying the data.
In this small series I will show you how to use Arduino IDE with ESP8266 and log your temperature data to the MySql server trough Node Red. And for data transmission we will use MQTT.
Eclipse Mosquitto™ is an open source (EPL/EDL licensed) message broker that implements the MQTT protocol. MQTT provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for “Internet of Things” messaging such as with low power sensors or mobile devices such as phones, embedded computers or microcontrollers like the Arduino. And I will show you how to install Mosquitto to RaspberryPi
