The resulting system should include the following:
- Visualization of values and system state
- Web interface–remote access
- Local preview with the option of scrolling through screens
- Sensorics
- Central measured variables
- temperature
- humidity
- atmospheric pressure
- real-time clock
- External measured variables
- air temperature
- air humidity
- soil moisture
- light measurement
- Actuators
- audio signalization
- ventilation
- air circulation and heating
- controls (button, potentiometer, PIR sensor)
- Ability to store and work with the measured data
- microSD
The entire solution of greenhouse automation can therefore be expressed clearly with block diagram of the HW communication of Arduino and its surroundings, as shown in figure 1.
Meteo Shield
Meteo shield is a commercially manufactured component for the Arduino platform. In the case of greenhouse automation, it’s used to take temperature, humidity, and atmospheric pressure measurements in its immediate vicinity. Another feature of this expansion is the ability to work with real-time clock. This enables the unit to become independent in time orientation and allows for time event planning.
