How smart can a mini greenhouse be that costs less than 20 Euro? As so often, the answer would be: It depends. With the right hardware and software, even the smallest greenhouse can become „smart“.
The official Eclipse IoT tutorial (a mini mini greenhouse) uses Eclipse Kura, Paho, Californium and a Raspberry Pi, a temperature and a humidity sensor to implement a basic IoT example based on Eclipse IoT projects. In the video we demonstrate a more complex example that leverages the power of OSGi and uses some more sensors and actuators.
