Gravity - Analog Electrical Conductivity Sensor - DFRobot DFR0300-H

Index: DFR-15096 EAN: 5904422348359

The device allows to measure the salinity of waters and soils by examining the inverse of the resistance, which is conductivity. The conductivity of water can reflect the level of electrolytes present in it. Depending on their concentration, the conductivity of the water solution varies. A constant K electrode is equal to 10.

Description: Gravity - Analogue water and soil salinity sensor - DFRobot DFR0300-H.

The device allows to measure thesalinity of waters and soilsby examining the inverse of the resistance, which is conductivity. If the salt level is too high, this can lead to the destruction of the plants, and if it is too low, it can mean a nutrient deficiency. Water conductivity may reflect the level of electrolytes present in the water. Depending on their concentration, the conductivity of the water solution varies.

Connection diagram

The meter has been designed for Arduino controllers andhassimple and convenient built-in functions. Connecting the sensor is easy, thanks to the Gravity connector.
