The problem Smart IOT Plant Monitoring with Live Dashboard solves

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.
I used the Cayenne Online Dashboard to connect my ESP32 with the cloud. The following sensors were used for monitoring the plant - LDR sensor for light intensity, DHT11 sensor for temperature and humidity, Soil moisture sensor and MQ135 for air quality sensor. I also used a Nokia 5110 LCD for displaying the same values near the system too.

It 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.

Here's the link for my IOT Garden Dashboard - https://cayenne.mydevices.com/shared/60d7bf30518adb4d4aeb12f0 - IT'S LIVE You can see 5 graphs each for sun light intensity, soil moisture, humidity, temperature and air quality. Anyone can access the link from anywhere.

Challenges I ran into

It was fun working with all these sensors and IOT. I was facing some issues while connecting the Nokia 5110 LCD with the ESP32 as i needed to connect some resistors. But then I was able to figure it out by calculating the correct resistor value.
