The diagram explains the process of an automatic irrigation and heat lamp system to care for a plant and what they combine.
Overall, the system is composed of four essential sections and other subparts to perform two functions.
According to the diagram, the most important unit was a microprocessor (Arduino) which played as a brain in the system and accompanied by a receptor was the temperature sensor (DHT11). Besides, it was also crucial parts in the system as the irrigation system and heat light which protected directly the plant from the transformation of temperature.
The standard temperature was set in a range of 30 to 31 degrees. If DHT11 detected the environment temperature was hotter than 31 degrees, the system would be in response to the changing by activating the irrigation system to reduce the degree of heat until the temp was as low as the standard then stopped watering the plant. On the other hand, the lower temperature than 30 degrees activated the heat lamp to increase tempt inside the greenhouse until it was equal to the normal.
