<p>The system has a plastic shell containing an electronic board, and a humidity sensor (12) measuring humidity rate of ground. A temperature sensor measures an ambient temperature of plants, and a luminosity sensor (8) measures sunshine time of plants. Values of the humidity rate, ambient temperature and sunshine time are defined by respective coding wheels (2, 5, 10) according to the characteristics of plants to be monitored. Two-colored LEDs (1, 4, 9) visually warn a user when an anamoly such as too much or low humidity, heat and sunshine, is detected.</p> |
