Soil Moisture Sensor, which can monitor the moisture level of soil and send out instruction to the controller to skip watering when soil is too wet.
Select the desired soil moisture level, S: (25% volumetric ratio). M: (45% volumetric ratio). L: (65% volumetric ratio). Three options allow for more flexible soil moisture control to keep your garden in its best condition
Easy to use. After installing the 2*AA alkaline battery set the desired soil moisture level and connect the sensor to the controller. Insert two detection probes fully into the soil. Clean the probe after each use.
Frequency of moisture level checking: 1 time per minute. When voltage is below 2.4V, all LED will blink together once per second, which is a warning that new batteries are needed. When the sensor is off, send the sensor off instruction to the controller
Design to be light and portable and easy to carry around for outdoor use. Ideal soil test meter for home, garden, lawn and farm, both soil-less mixtures and soil grown plants.
