Farm 2.0

https://github.com/salimkhazem/Smart-Farm-

Operation:
This device allows intelligent management of water distribution on agricultural land (watering) and the ventilation of the farm (greenhouse), equipped with a digital sensor in this case sensor temperature and humidity, so the l watering will be done as needed from the ground, so if the humidity is lowered, the sensor will send a signal to the device (in this case it's the Arduino board), it will trigger the solenoid valve that will allow watering plants, and it will be the same for the air conditioning, the ambient temperature will be intelligently controlled thanks to the sensor and the release of conditioned air, as far as the code is concerned, I made sure well comment on it for a better understanding

for the code it's simple, I made conditions on the sensors (temperature, pressure, humidity) after obviously having defined the threshold

With regard to the material:

Arduino, microcontrollers(Atmel,Pic)
Analog sensors(temperature sensors, humidity sensors,pression sensors)
Relays
engines
Solenoid valves
Graphic interfaces (LCD ...)
Before running the program you must add the libraries to the Arduino libraries folder.

To do this: copy the two folders (Adafruit_Sensor and DHT) that are in the libraries folder (the one I put), paste them in the arduino libraries folder.
