Abstract
A water hardness detection probe, sensor, detection method and water softener are provided. The sensor includes a control unit which includes a processing module and a potential detection module. The detection probe includes a first probe and a second probe. When the first and second probes are both exposed in raw water, a potential between the first and second probes is regarded as first potential. When the first probe is in the raw water and the second probe is in softened water, the potential between the first and second probes is regarded as the second potential. The potential detection module measures the potential between the first and second probes. The processing module determines the water hardness of the softened water according to a difference between the first potential and the second potential. The sensor can detect the water hardness of the water softener in real time and eliminate detection deviations.
