5.3 Setting Irrigation parameters
Setting the pulse duration
The pulse duration is defined in ms. The default value is 20ms and it can be modified at 200ms as maximum.
Must be considered that higher is the pulse duration higher will be the power consumption.
Valve output enable
If it is necessary and to preserve the battery life, it is possible to enable and disable the activation of the outputs.
Each output can work in independent way.
Timetable irrigation identifier
To reduce the datalength of the communications between endnode and server it is necessary to assign an
identification number to the timetable (from 0 to 65535). This parameter will be sent instead of the complete
irrigation plan.
Setting the timetable
The timetable is defined along the day (24h) and it is divided in 15 minutes slots. This is the minimum time to
carry out an irrigation operation. The number of operations is unlimited.
On the other hand, the timetable can be applied depending on the day of the week.
5.4 Checking the setup and establishing first communication
Once the equipment has been installed and the configuration parameters has been programmed according to
user requirements, Watersens is ready to send and to receive data from server.
In most cases the coverage of the network is unknown and it depends on distance and relative height between
node and gateway, the size and the quantity of obstacles in line transmission (as buildings), climatic conditions,
etc. To ensure the success of data transmissions is recommended to initialize the Watersens communications
at minimum data rate and maximum transmission power using the mobile application option «Reset COMs».
On other hand configuring «Time to update status» at value 0 also is recommended to increase the quantity
of transmissions performed by the equipment (each 3 minutes).
If adaptive data rate is configured as auto (network controls the data rate of the Watersens) after several
communications, server and node will adapt the data rate to the value which the occupation of the band and
the power transmission of the node will be lowest. In this case and if it is not necessary, user can modify the
«Time to update status» to lower value to save energy from battery.
Finally to proceed the irrigation task properly, is necessary to configure date and time. These settings can be
adjusted through Lora commands as can be chapter «Data frame format».
