CLIMAVI is a family of energy self-sufficient, high-precision, and competitive wireless sensors, which can be installed in an agricultural field, in the forest or in gardens. A few hours of sunlight are sufficient to ensure a stable power supply for days. CLIMAVI IoT-sensors transmit data every 15 minutes over several kilometers to a compact receiver station. The strongest asset of our product is the capability of measuring soil moisture and temperature, air humidity and temperature, ultrasonic wind speed and direction, precipitation, UV- and sunlight irradiation and climate gases like CO2 permanently and in a cost-efficient way. The complete microclimate data can be viewed in the user-friendly FARMALYZER app. Different data sources such as satellite data, ordinary weather forecasts, machine and soil data are merged automatically to further increase the reliability of the recommendations.
