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.
