A Solar-Powered Soil Sensor for Serious Gardeners
J Thoendell stashed this in Tech
The current incarnation of Edyn tracks soil moisture, nutrition, temperature, humidity, and light, and its sidecar iOS app (there’s an Android version coming soon) includes a database of thousands of plants to recommend what to do in various cases. The app will also offer up a selection of plants that should grow well in your soil and climate conditions based on its readings.
You don’t need to actively charge it, either. Aramburu says the garden sensor charges fully with about three hours of sunlight, and indoor grow lights are also strong enough to keep its battery juiced. Once fully charged, the unit stays running for about two weeks.
The sensor itself is rated to gather readings for a 250-square-foot patch of land. The Edyn Garden Sensor requires Wi-Fi to work, which is a potential limitation for remote locations; Aramburu says the unit is rated for a 300-foot range in relation to a router, although there’s been success establishing a line-of-sight connection of up to 1,500 feet.
“We are actively experimenting with other radio frequency (RF) technologies that do not require Wi-Fi and can be deployed on a much larger scale,” says Aramburu, who also says the team is working on app features that could be useful for farmers coping with California’s current drought. “We will also continue to develop our software so that farmers and gardens can track their water usage, and benefit from any incentives for conserving water.”
