PROBLEM TO BE SOLVED: To drastically reduce the number of a mounted connector in a main board, to make the main board compact and to realize cost reduction. SOLUTION: A sensor system comprises an input signal interface, an output signal interface, a switch circuit 11 opened/closed by a sensor signal and a resistor circuit 12 connected parallel to the switch circuit 11 and is provided with a plurality of serial interface parts 2 wherein the output signal is short-circuited to the input signal according to a sensor signal state or connected through the input signal and the resistor circuit, and a microcomputer board 4 connected to the serial interface part 2 of the last stage to recognize the state of a sensor signal to be inputted to each serial interface part 2 by an AD conversion input voltage.
