Description
LDTR-WG0237 Plant Watering Alarm Humidity Moisture Sensor for Arduino (Black)1. 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. 2. Special care has been taken

Works much better than the original applicator which left streaks and overlaps
Works much better than the original applicator which left streaks and overlaps. Much easier to use on contours and crevices.

Game Changer!
So much better than the applicators. Easier to get nice even application on RVs. Does much better getting around the awning poles and different covers.
