PRODUCT DESCRIPTION

Let the soil moisture set the irrigation automatically, not an app or equation. Make it simple. WS-601 is a wireless sensor kit that can operate a valve automatically (via WB-100 receiver) without any app or human interaction or a controller. Set the desired moisture level on WS-601 with a knob (NOT an app, shocking! isn't it?) and WS-601 automatically maintains the soil moisture by operating the irrigation valve. No guessing, no app, nothing on cloud, no more sticking fingers or screwdriver (or keys) to check the soil moisture, no prediction, no graph, no analysis, and no equations of any kind. Set it and forget it, it is really that simple. WS-621 operates from sun-down to sun-up.
