Hi again.
i have created a watering system using labview. There are two differents watering areas manageb by this virtual instrument.
It has trhee operation modes.
Watering in manual mode. In this choice, you active the valve by pushing the activation button (riego manual 1) or (riego manual 2). When you select this mode, the virtual instrumnent sends an e-mail to the previusly address selected.
Watering runs by time. If we select this option in watering mode (modo de riego), the system starts to watering the selected area at the specified time, and it is going to keep doing it for the selected time. For example, the
picture shows that the starts time will be 13:56 and it is going to watering the first area for 20 minutes.
If we select the water by sensor mode (riego por tensiometro), the visturl instrument, will read the sensor information and if the data is under the low level specified, it will start to water until the data read, will be up to the high level (selected before).
The whole block diagram is shown on the file attached :
