Abstract:
A sensing device, comprising:a first resistive branch comprising first and second resistors connected in series; a second resistive branch comprising third and fourth resistors connected in series, the second resistive branch being arranged in parallel with the first resistive branch to form a bridge circuit; a signal output circuit connected with the bridge circuit and configured to generate a detection signal representing the target condition; a first substrate on which the first and second resistive branches are provided; a second substrate on which the signal output circuit is provided; a power source line formed on the second substrate for connection to a power source; a ground line formed on the second substrate for connection to a ground; a first feed wiring arrangement connecting the first resistive branch to the power source line; a second feed wiring arrangement connecting the second resistive branch to the power source line; and a ground wiring arrangement connecting the first and second resistive branches to the ground line.
