Story
Most plant monitoring systems are only able to be monitored in local area networks as accessing the system from outside the local network becomes costly or difficult. I decided to make such a plant monitoring system but with the added ability to access the various values FROM ANYWHERE IN THE WORLD.
What it doesIt can monitor my garden statistics in a very detailed graphical format from anywhere in the world. As I am the dashboard ADMIN, I can even make some changes in the dashboard and make some analysis. Even others can monitor the garden sensor values with just a simple link.
Setup Cayenne Dashboard for ESP32If you do not have an account on Cayenne, create an account from the following link: https://cayenne.mydevices.com/cayenne/signup
In this project we are using ESP32 so select “Bring Your Own Thing” but if you are using Arduino or Raspberry Pi you may select the same as shown in the screenshot.
By clicking on "Bring Your own thing" we will get the MQTT username and password. Then name the device as ESP32, as shown in the screenshot.
Now open Arduino IDE and install the Cayenne MQTT library or download the library from Github by clicking on the following link:
https://github.com/myDevicesIoT/Cayenne-MQTT-ESP
Also, install ESP32 board package and select your ESP32 board from the Tools menu.
