The wire sensor is constructed using oxidation resistant wire which vastly improves it's lifetime and allows near optimal functionality. Such materials resist rusting or any form of degradation which positively supports the sensor's operation in wet conditions, or in places with normally highly corroding substances. In both cases, be it a rest room or rest room lighting outdoors, this sensor works flawlessly and not only performs reliably but accurately over long periods of time seamlessly and effortlessly.
