Top Sales Item
Plant Watering Alarm Sensor
This sensor will be silent when it?s dark and will restrict itself from making too much noise.
This is a plant watering alarm - as simple as that. You put it into the soil near a plant and it emits
a tiny chirp when the soil is dry, reminding you to water the plant. It uses capacitive humidity sensing
as opposed to resistive humidity sensing, this means, it does not make an electric contact with the soil,
avoiding electrode corrosion and soil electrolysis and resulting in better accuracy and longer battery life.
