Abstract
A dual-switching sensing device includes two sensor modules and a dual-function switching circuit with an operational amplifier and two integrator modules. Each of the integrator modules includes a transistor, an integrator capacitor and a switching unit. Through control of the switching unit, each of the integrator modules may operate in different modes, so that the dual-switching sensing device may be used to sense different targets.
