1. The problem

    Microgreens require lighting that can be easily controlled.

  2. The idea

    Use the Blynk app to turn on the lights.

  3. The prototype

    An app and an ESP32 control a relay that turns on the lighting. The entire structure is assembled from polymer tubes.

  4. The result

    We calculated the required illumination based on the daylight hours. Plants will grow faster.

What we learned

Basics of IOT and programming, how to calculate economic impact, and how to properly care for plants

Materials and tools

ESP32, C, электрическое реле, Blynk
