Garden watering has never been so easy or precise: the innovative GARDENA soil moisture sensor automatically waters your garden as needed and saves water by measuring the current soil moisture level and transmitting the data to your irrigation controller. If the soil is still sufficiently moist, the next watering cycle is skipped. In this way, your plants receive reliable and precise care automatically, while you save water as an added benefit. The sensor is compatible with almost all GARDENA irrigation control systems and multi-channel systems. Thanks to its compact size, the battery-operated soil moisture sensor is suitable not only for lawns and flower beds, but also for small flower pots.
