Urban Jungle Guardian has 2 important functions
Exam the light level
A photoresistor can sense the light level(Illumination) of the sunshine and protect pot plants from being overheated. If illumination lux is high, the speaker will play music to notify the planter; if the illumination lux is low, the yellow LED will bright up. The best condition for the plants should have no sign.
Exam soil humidity level
A soil moisture sensor should be put into the dust of the plant pot and evaluate the dust humidity. If the dust is in the right humidity, the speaker will play music. If the plant is in a good humidity level, green LED will light up. The planter should use it to test the dust humidity at least one time a day.
