Product description: Gravity - Analog Electrical Conductivity Sensor PRO - analog sensor of electrical conductivity of solutions - DFRobot SEN0451
DFRobot Gravity sensor that allows you to measure the electrical conductivity of an aqueous solution. The electrical conductivity of a liquid can represent the amount of dissolved oxygen or salinity, allowing water quality to be monitored . These types of sensors are often used in hydroponics, aquaculture and other fields. The pro version has a high-strength probe that allows you to take measurements around the clock. The integrated platinum PT1000 sensor enables temperature measurements. The sensor is powered with the voltage from 3 V to 5 V , its output is an analog signal with low jitter, hardware filtered. The excitation source adopts the AC signal, which effectively reduces the polarization effect, improves the precision and prolongs the life of the probe. The sensor works with 3.3 V and 5 V control boards, such as Arduino .
