Main Functions:

1. This system has 2 control modes:

1) Moisture sensor based control. Keep soil moisture in the setup range. Will automatically adjust irrigation by season.

2) Reliable Timer with max moisture control. Timer schedules will send to and performed by the field controller for reliability.Will stop irrigation when the maximum wet is reached.

2. System controls up to 50 wireless irrigation zones, or 200 valves.

3. Once setup, system will automatically keep moisture in the desired range to optimize irrigation.

4. All field controllers/relays are solar powered, through local mesh network to communicate with main controller. No need of any power line or communication line.

5. Built-in WIFI or 4G for remote control and monitoring.

6. Pressure meter used to detect leakage or jam of pipes.

7. Supportwired or wirelessweather station.

8. User can choose to install rotating cameras and video cameras accordingly, for monitoring irrigation in real time.

9. Air humidity sensorto control film rolling machine to open/ close greenhouses at real time.

10. EC / PH sensors.

11. Advanced Setting includes: Frost/Heat protection, Rain delay, Password protection, ID setup and Sampling cycle.

12. History files of moisture, irrigation events and alarms etc,.

13.Detailed and accurate SMS alarms as following, more details please check the SMS ALARMfile:

  1）If one devise failed wireless communication 10 times continuously.

  2）Monitoring power of all wireless devices in the system. Will issue alarm when battery hit low.

  3）No or little continuous charging signal has been detected from the solar panel charging circuit.

  4）By checking how steep is the discharge speed at night for several cycles.

  5）After the valve has been open, delay time past, check the water pressure meter reading.

       If the reading is higher than closed status, normal, otherwise alarm.  

  6）After the valve is closed, delay time is over, if the water pressure meter reading is over reading

       of closed status of the valve, then alarm.

  7） System will check water pressure every minute during irrigating period. If the reading is less than normal range three times straight,

       system will judge as there is possible leaking, protectively turn off the valve. Then you only can cancel the protective

      status by field manual operation, or remote operation

  8）Notice of zone irrigation at very beginning.

  9）There are three kinds of sensors to protect the pump: liquid level sensor, flow sensor and pressure sensor.

        During pump starting, if any reading of these three sensors are out of setup range, then turn off pump and alarm.

        The pump will not restart until there is field maintain, or remote recover because the reason is not enough water pressure.

  10）Moisture sensor chart analysis. See example of following chart. There are lots irrigations which should not happen.

  11）a. If reading of moisture sensor reached abnormal 99% multi times continuously, alarm. The moisture sensor is very possible go bad.

          b. The reading of moisture sensor is more steep than history chart, alarm.

          c. If the reading of moisture sensor has no increase after 3 times of irrigation, then alarm.

  12）Flow rate of monitored sensor is out of range. Is turned off.

  13）Reading of related pressure meter is out of range

  14）If there is no internet connection for main controller over 24 hours, alarm.

  15）Remind customer to pay/renew cloud service, start from one month before due time, then once a week.

  16）When the soil moisture reading is lower than the Dry threshold over 2 hours, alarm.
