The system is for washing-out the sanitary apparatus automatically by detecting the user. The system comprises a sensor (2) for detecting the user, a control circuit (3) operated by the sensor, and a valve (4) providing water for cleaning out sanitary devices (1). The sensor detects the ultrared ray generated from the human body and transfers it to the heat at a pyroelectric element so that the variation of the heat converts to the electric signal. |
