5km Wireless Irrigation System 4 Station Field Controller 5km Wireless On Off Control

Product features:

1. Controller is solar powered.
2. Only need one key push to setup Dry/Wet control threshold. Very easy to use.
3. Has manual key to manually open/close valves for the convenience of field operation and maintain.
4. With pressure meter installed to check valve open/close abnormal, alarm to main controller if there is failure.
5. This controller also function as relay. The built in bidirectional wireless distance can reach 2000m through mesh network.
6. The moisture sensor can bury deep in the soil.
7. If there is not enough solar power, the controller will turn off valve first, then turn self-off, recharging , and wake up automatically after recharged.
8. Field controllers in the range will automatically setup mesh network route to communicate with main controller.
9. This controller can work for almost one month under rain/cloudy days.
