The innovative Soil Moisture Sensor from Gardena is designed to work with almost all Gardena Water Controls and Multi-Channel Controls. It ensures that your garden is watered according to demand by measuring the current soil moisture and transmitting this data to your Water Control. If the soil is still sufficiently moist, the upcoming watering cycle is skipped. In this way, your plants automatically receive reliable and accurate care, and you save water. Due to its compact size, the battery-powered Soil Moisture Sensor can not only be used in lawns or flowerbeds, but is also suitable for smaller plant pots. To ensure that the sensor does not interfere with lawn care, it has a particularly low height and a flat surface: both lawn mowers and mowing robots can easily drive over the sensor. The Soil Moisture Sensor is powered by two standard AA batteries (not included). The batteries should typically last around a year of normal use, and if they are running low, an LED indicator will light up to signify that they are almost drained. This will also be indicated on the Water Control unit.
