The "lonely plan't" is an IoT plant interaction device, which encourages the owner to interact with the plant in order to maintain its health.  In short, the device contains a soil moisture sensor.  When the moisture is low, the device alerts the user in 2 ways:  text and an illuminated blue light.  In order to satisfy the plant, however, the owner must spend time with the plant.  The first criteria is that the plant is in a well-lit area.  Second, the owner could talk to the plant, play music for it, or other interactive activity that involves sound.  This will trigger the device to water the plant.  Once the plant is sufficiently watered, a green light will appear, indicating the plant is satisfied.
