Sensor device and output characteristic switching method of sensor device

A pressure sensor device ( 1 ) includes a sensing element ( 2 ) for sending an analog signal according to pressure. The pressure sensor device ( 1 ) outputs the analog voltage to a microcomputer ( 20 ) through an input-output terminal ( 8 ). An input-output control circuit ( 4 ) monitors the voltage...

Zusammenfassung:	A pressure sensor device ( 1 ) includes a sensing element ( 2 ) for sending an analog signal according to pressure. The pressure sensor device ( 1 ) outputs the analog voltage to a microcomputer ( 20 ) through an input-output terminal ( 8 ). An input-output control circuit ( 4 ) monitors the voltage value in the input-output terminal ( 8 ). When the voltage of the input-output terminal ( 8 ) is set to high by the microcomputer ( 20 ) and is dislocated from a predetermined range, the input-output control circuit ( 4 ) functionally changes the input-output terminal ( 8 ) outputting a detecting signal to a terminal for inputting an external signal from the microcomputer. After the input-output terminal ( 8 ) is changed to the terminal for inputting the external signal, a range control circuit ( 7 ) fetches an external command signal through the input-output terminal ( 8 ) and switches the output characteristics.
