SENSOR SIGNAL DETECTING CIRCUIT AND SENSOR MODULE

摘要

PROBLEM TO BE SOLVED: To provide a sensor signal detecting circuit at a low manufacturing cost.

SOLUTION: The sensor signal detecting circuit includes: a sensor signal outputting section 6 which is connected with a sensor 2 outputting two voltage signals corresponding to a sensing result, and outputs a sensor signal corresponding to a voltage difference between the two voltage signals; and an offset removing filter 8 for removing a DC component from the sensor signal.
