A separate component, the Edyn Water Valve, uses the data collected by the sensor to smartly control the existing watering system, watering the plants only when needed.
Edyn passes a harmless electrical signal through the soil in your garden and measures how that signal is altered or attenuated by water and soil additives, such as organic fertilizer, lime or compost. Edyn cross-references this information with their database and the other members of the Edyn community. Edyn’s instruments are calibrated to be sensitive enough to detect small changes in the soil’s electrical properties that are associated with shifts in moisture, acidity and fertility.
The sensor is Solar-powered and Wifi-connected to the Edyn Cloud. It is water and fertilizer-resistant and measures ambient temperature, humidity, light intensity, soil nutrition, pH and moisture. A machine learning algorithm analyzes live sensor data on the device and in the cloud. The App reports soil nutrition, moisture, light and temperature in a snapshot of the garden, now and over time.
