rs485 water pipe leak detector sensor/water pipe leak detector

use the alternating current to collect the water inductor parameters, accurate distinction between whether the flooding, or even distinguish between pure water and tap water (default to tap water for the detection of pure water, if you want to test, please specify). Because the use of alternating current detection, even if the electrode immersion does not produce long-term electrophoresis polarization, do not rely on special electrodes, to achieve long life, reliable detection. --- This technology is our patent, has been authorized by the Patent Office, where counterfeit our company reserves the right to pursue its legal responsibility.
