Abstract
A battery-operated object detecting device (D) includes a detecting unit (U) adapted to be driven by an electric cell () mounted thereon, and a transmitting device () driven by the electric cell () in the detecting unit (U) for wireless transmitting at least a low battery signal being indicative of a reduction in voltage of the electric cell (). An electric power sharing unit () for outputting a supply voltage to the transmitting device () includes a voltage changing circuit () for changing, based on a low battery detection result from a low battery detecting circuit (), to a voltage necessary for causing a low battery determining circuit () of the transmitting device () to change the supply voltage from the electric cell () to a voltage for determining a low battery state.
