The present invention relates to a system to detect water level and water quality comprising: a water contacting sensor unit installed in a water tank to selectively apply an electric current with a ground connection in accordance to whether it contacts the water stored up to a certain level; a water level detecting module to determine if water stored up to a certain level in accordance to a first return signal returned by providing a pulse wave signal to the water contacting sensor unit; and a water quality detecting module to determine the quality of the water stored in accordance to a second return signal returned by additionally providing a Hi-Fi signal to the water contacting sensor unit when the water level detecting module determines that the water is stored up to a certain level. According to the present invention, the level and quality of the stored water can accurately be detected in a stable way. |
