PROBLEM TO BE SOLVED: To provide a sensor system configured so as to eliminate the drift effect for example by a simple constitution. SOLUTION: An electrical circuit of one embodiment includes a reference signal generating circuit (a gate clock generating circuit 130) for generating a reference signal (a gate clock signal 131), based on a first oscillation signal 121a as an oscillation signal from a first oscillation circuit 120a connected to a first oscillator 110a; and a counter circuit 140b for counting a second oscillation signal 121b, and outputting a change quantity in a counted value of the second oscillation signal 121b as a count signal, based on the second oscillation signal 121b as an oscillation signal from a second oscillation circuit 120b connected to a second oscillator 110b and based on the reference signal (the gate clock signal 131).
