Gravity: Analog Electrical Conductivity Sensor / Meter For Arduino is especially used to measure the electrical conductivity of aqueous solution, and then to evaluate the water quality, which is often used in water culture, aquaculture, environmental water detection and other fields.
This product, greatly improves the user experience and data precision. It supports 3~5v wide voltage input, and is compatible with 5V and 3.3V main control board.
Furthermore, the output signal filtered by hardware has low jitters and the excitation source adopts AC signal, which effectively reduces the polarization effect, improves the precision and prolongs the life of the probe.
The software library uses two-point calibration method, and can automatically identify standard buffer solution, so simple and convenient.
With this product, main control board and the software library, you can quickly build an electrical conductivity meter, plug and play, no welding. It provides a variety of water quality sensor products, uniform size and interface, not only meet the needs of various water quality testing, but also suitable for the DIY of multi-parameter water quality tester.
Conductivity is the reciprocal of the resistance, which is related to the ability of the material to carry the current. In the liquid, the conductivity is the measure of its ability to conduct electricity. Conductivity is an important parameter of water quality. It can reflect the extent of electrolytes present in water.
