Eduponics Mini

An ESP32 smart agriculture IoT kit with a modifiable app

This project is coming soon. Sign up to receive updates and be notified when this project launches.

Eduponics Mini is a smart agriculture and IoT board based on the ESP32 microcontroller. It features a rich number of built-in sensors: temperature, humidity, barometric, ambient light, water quantity, soil moisture, and more. It is also equipped for Wi-Fi, Bluetooth, and low-power consumption support to enable real-life IoT applications. Eduponics Mini comes with a hackable mobile app that enables remote control of your plants from anywhere using the MQTT protocol. It’s industrial-grade hardware at an affordable price - an excellent ready-made irrigation system, automatic watering for your plants, or as an educational tool that collects highly accurate sensor data and performs automation.

Open Source Information

Our documentation can be found at:

We provide a very detailed documentation of each sensor, the principles and code examples for both Arduino IDE and MicroPython.

Our GitHub repository can be accessed here:

We haven’t created any special firmware. All the code libraries and drivers (with their owners credits) are fully open source and are available on GitHub and in our Wiki.

We also provide the MQTT code to control our Eduponics mobile app (currently only available on Android). While the app code is not published, we do offer ESP32 side code that can modify all the data in the app, which means anyone can use the code for our app without having to use our hardware.
