1. A physiological monitoring device comprising:
at least two groups of LEDs coupled to a substrate, the at least two groups of LEDs configured to emit light of at least two different wavelengths, wherein each group comprises at least a plurality of LEDs, wherein a thermal mass of the substrate stabilizes a bulk temperature of the at least two groups of LEDs;
at least one detector configured to detect at least a portion of the light emitted from the at least two groups of LEDs after at least a portion of the light has been attenuated by tissue, the at least one detector configured to output at least one signal responsive to the detected light;
a substrate temperature sensor coupled to the substrate, wherein the substrate temperature sensor is configured to measure a temperature of the substrate and wherein the temperature of the substrate is responsive to the bulk temperature of the at least two groups of LEDs; and
at least one hardware processor configured to:
control an operating condition of the physiological monitoring device based on the bulk temperature of the at least two groups of LEDs; and
process one or more signals responsive to the outputted at least one signal to determine a physiological parameter of a user responsive to the one or more signals.
