ABSTRACT OF THE DISCLOSURE A battery-operated sensing and control circuit for a toilet room device such as a flush valve which is operated by an electric solenoid includes a continuously operable primary sensor and an intermittently operated secondary sensor. The primary sensor detects the presence of a user adjacent the toilet room device and starts a timing cycle. The secondary sensor is only powered up during the timing cycle and as soon as the secondary sensor has detected a user in front of the toilet room device, the timing cycle is terminated. All components, including the sensors, the timing device and the electric operator, are powered by a battery.
