Wireless reception and recording of soil moisture levels and soil temperature in the scientific sector, for agricultural applications as well as garden and landscaping construction. Data are stored on a cloud server and can be downloaded to laptops and handies.
AREA OF USE
Agriculture irrigation monitoring
Irrigation monitoring of expensive plantings
A Dashboard provides data for access from PC and cellular phones and other mobile devices.
Data shown on map
Public low power network:
In this case, so-called gateways - access points to the Internet - are already installed nationwide by a telephone provider. These antennas are usually mounted on the existing mobile phone antenna masts, which are naturally placed in elevated positions. Such a nationwide LP network is e.g. already available in Switzerland, Holland and South Korea.
Private low power network:
In order to be able to use this technology even in countries without a public LPN, one can buy a private gateway and use this e.g. in a building under the gable. This considerably increases the range. Using a network cable, it must then be connected to a router - which is virtually always available for access to the Internet .

PlantCare’s worldwide patented sensor technology is based on the microthermic measurement of soil moisture. A specially developed felt material in moisture balance with the soil acts as the interface between the surrounding soil and the sensor. To measure the moisture level, the sensor is briefly heated and the cooling-down time, which varies depending on soil moisture, is determined. The sensor's cooling-down time thus provides a reliable statement of the soil's moisture content.
As with an automatic PlantCare irrigation control, the monitoring system is based on the use of wireless PlantCare soil moisture sensors. The user places two or more sensors in the field to be monitored and they periodically report soil moisture to the gateway by radio. This sends the data to a server where it will be prepared accordingly. The data can be accessed at any time via mobile phone or PC.
Likewise, alarm values can be set. The system sends a message to the user when the limit values are exceeded or fallen below.
