The Water Content Sensor (WCS-1) is specifically designed to measure the water content data (percentage) of the grow media in the Aqua-X Control System. Each set of WCS-1 includes a three-prong sensor and a transfer module (Display Screen & Button). When measuring, the three prong sensor of a Water Content Sensor is inserted into the grow media such as soil or rock wool to be measured. If there are multiple Water Content Sensors (up to 8pcs) to be connected to the NFS-1 Controller, the NFS-1 screen will display the average value. After downloading the app, you could read the water content data (percentage) and historical data (graph) on your Smartphone and receive message if the current value of the grow media exceeds your highest and lowest alarm setting range.
