Read full description

VISUAL SENSOR is a precise monitoring service for crop climate and soil, providing 15 agroclimatic parameters every 21 minutes. It is the result of research into the best existing solutions for improving crop efficiency and sustainability, helping optimize water consumption and determining the optimal timing for treatments. Through sensor data, you can track and analyze agronomic and environmental parameters. These systems gather information that allows the user to make decisions with great precision related to irrigation planning, crop monitoring, optimal treatment timing, and harvest timing. It is an intelligent agriculture model with data that considers historical information, real-time data, and predictive models. It reduces potential risks that crops may face due to forecasts of heavy rains, frost, or heatwaves. With VISUAL SENSOR, you will combat yield reduction and have real-time monitoring with your fields connected, from the very beginning and throughout the year, wherever you want. It will always be available and accessible from any of your devices. What does it include? Connection to agroclimatic event prediction systems for a 7-day outlook and also connection to thousands of public network stations, which you can select without limits and combine to create an information panel with high capabilities for comparison and tracking of parameters affecting crops. All these stations are geolocated and visually displayed on a map, helping you get an overview of field and crop conditions at a glance. You can connect with sensors and stations from other manufacturers; we support interconnectivity to enhance the user experience and environmental awareness, always aiming to provide greater precision to the system. You can share access and availability of information with as many guests and collaborators as you choose. The agile and simple communication makes management systems more efficient; hence, we facilitate communication within the user's collaborative community. Once installed, it automatically geolocates and starts receiving data, alerts, and predictions from the very beginning, with simple interfaces that aid in interpreting and reading data. It's also available in audio mode to enhance accessibility and avoid physical contact. It has been developed by the specialists at VisuaNACert, taking into account agronomic knowledge and the feedback clients have provided over the years, as well as their needs, risks, and opportunities to achieve better and more sustainable agriculture.
