Multi-sensor detector with adjustable sensor sampling parameters

A multi-sensor detector comprising:

• a first, ambient condition sensor;
• a second, different ambient condition sensor;
• control circuits coupled to the sensors for responding to a condition indicating output from the first sensor by altering a sampling related parameter of the second sensor to increase the signal-to-noise ratio of output signal.

A multi-sensor detector comprising:

• a first ambient condition sensor;
• a second, different ambient condition sensor;
• control circuits, coupled to the sensors, responsive to a predetermined output from the first sensor for switching the second sensor from a first level of resolution to a second greater level of resolution.

A multi-sensor detector comprising:

• a first ambient condition sensor;
• a second, different ambient condition sensor;
• control circuits, coupled to the sensors, responsive to a predetermined output from the first sensor for switching the second sensor from a first mode of operation with a first signal-to-noise ratio to a second mode of operation with a second, improved signal-to-noise ratio.

A multi-sensor detector comprising:

• a first ambient condition sensor;
• a second, different ambient condition sensor which includes a radiation-emitter and circuitry to sense radiation from the emitter;
• control circuits coupled to the sensors, responsive to an output from the first sensor to alter a drive amplitude parameter of the emitter.
