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.
