Control up to 4 moisture sensors. For measuring moisture at different depth, for the application of deep root crops, or for average moisture level from different moisture sensor. Solar powered only, using standard 10*2300mAh AA size Ni-MH Battery, the battery is not included.

Product features:
1. Controller is solar powered.
2. Only need one key push to setup Dry/Wet control threshold. Very easy to use.
3. This controller also function as relay. The built in bidirectional wireless distance can reach 2000m through mesh network.
4. The moisture sensors can bury at different depth for different application.
5. If there is not enough solar power, the controller will turn self-off, recharging , and wake up automatically after recharged.
6. Field controllers in the range will automatically setup mesh network route to communicate with main controller.
7. This controller can work for almost one month under rain/cloudy days.
