This is 4 in 1 water and soil sensor. The new generation sensor can be used for Ec, moisture, salinity and temperature measurements in both water and soil media as well. This sensor is a high quality Anti-corrosion, stainless steel industrial standard sensor that can measure soil and water EC (conductivity), soil and water moisture contents, Salinity and temperature. This sensor enjoys high precision, long life and high stability in measurements. The sensor has RS 485 serial interface with 2-meter cable which can be extended to 1000 meter without affecting measured data quality, thanks to RS 485 long distance serial communication interface. It can be integrated with GPRS/4G/WIFI/LORA wireless module.
