The STEMinds Eduponics Mini is smart agriculture and IoT board. With an ESP32 module at its heart, Eduponics Mini features an array of built-in sensors—including temperature, humidity, barometric, ambient light, RTC, and EEPROM. Externally, the kit includes water quantity, water pump, and soil moisture sensors—that work together to make smart agriculture easy and affordable. It supports Wi-Fi and Bluetooth connectivity and consumes very little power, making it perfect for real-world IoT applications.

Eduponics Mini can help you develop essential Industry-4.0 skills while creating real-world applications that are also useful in your daily life. Examples might include:

  • An automated plant-watering system
  • Environmental monitoring and data-driven irrigation projects
  • Hydroponics and aquaponics (using external sensors)
  • An IoT weather station
  • A smart aquarium- or reef-monitoring system
  • Research to inform plant growth and disease predictions

Custom mobile APP

We’ve designed and developed an easy-to-use mobile app for the Eduponics system. It has a React Native user interface and a public MQTT broker on the backend, which means there’s no need to deploy and maintain a database. It allows you to:

  • Control and monitor an unlimited number of plants
  • Water and monitor your plants remotely, from anywhere
  • Monitor soil moisture, humidity, temperature, and sunlight exposure

The Eduponics App currently supports soil-moisture sensors only, but we are working to add support for hydroponics and even smart-aquarium projects!

In addition, we’ve created a library to help you modify nearly every aspect of the app. With it, you can add plants, rename them, configure new sensors, and more. It is currently available for Android and will soon be available for iOS.
