ABSTRACT:
A sensor control circuit which includes a first sensor for detecting an event; a second sensor having identical characteristics with those of the first sensor for detecting the event at the same time; a processing unit having a first processing section for receiving and processing a first sensor signal from the first sensor and a second processing section for receiving and processing a second sensor signal from the second sensor; a first switching unit for switching in response to a first output from the first processing section; a second switching unit for switching in response to a second output from the second processing section; the first and second processing sections being made so as to turn on the first switching unit prior to the second switching unit in response to the first and second sensor signals; and a monitor unit for preventing current conduction to a load if the second switching unit is turned on prior to the first switching unit.
