PROBLEM TO BE SOLVED: To provide a water faucet control system capable of setting normal operation and special mode of a water faucet control device, and realizing miniaturization of sensor part and reduction in consumption by a combination of the cock control device and a remote-control device. SOLUTION: In this cock control system, the cock control device is equipped with an integration means and a control means, and the control means integrates the first output as long as a prescribed time in synchronism with pulse floodlighting, integrates the second output; immediately after finishing the pulse floodlighting, and determines that a human body is detected, when the output from the integration means reaches the first threshold level, and the remote-control device has function of receiving the pulse floodlighting from a floodlighting means, reversing the phase of the received pulse floodlighting, and outputting a light. It is determined as being the light signal input of the remote-control device, when the output from the integration means reaches the second threshold level that has having reverse voltage polarity, with respect to the first threshold level.
