SENSOR FOR DETECTING MICROORGANISMS AND WATER CLEANSING APPARATUS HAVING THE SAME

摘要

A sensor for detecting microorganisms and a water cleaning apparatus therewith are provided to improve accuracy of the sensor, to prevent corrosion of an electrode, and to lengthen the life span of the sensor by precisely detecting microorganisms in a liquid sample. A microorganism detecting sensor includes a power supply unit(201), an electrode(205) made of material restricting attachment of microorganisms connected to the power supply unit, a resistor(203) and a voltage measuring unit(204) connected to the power supply unit in parallel, and an electrode(205) connected to the resistor and the voltage measuring unit in parallel and made of material easily attached to the microorganisms. Gold, silver, platinum, iridium, zirconium or titanium restricts attachment of the microorganisms. A glass plate is coated by carbon, mixture of graphite powder of 60 wt% and silicon of 40 wt% or fine wires of less than 0.01 mm to easily attach the microorganisms.
