Place the sensor permanently in the ground next to the plant and the moisture content will be displayed by one of the 7 LEDs in steps of less than 2% to more than 20%.
The current moisture level LED flashes every 2.5 seconds. Even in the dark, the moisture content is still readable. Your plants are continuously monitored by the sensor. If the light shows less than 2%, give the plant water. Suitable for indoors and outdoors. Remove the sensor cover, remove the insulation from the battery (included) and after closing the lid, the sensor is ready for use
