Wearable computing device to adjust a current supplied to a light source of a sensor based on an amount of ambient light detected by another sensor

A computer-implemented method, comprising:

• detecting, by a first sensor disposed at an upper part of a body of a wearable computing device, an amount of ambient light in a surrounding environment of the wearable computing device;
• adjusting, by one or more processors, a current supplied to one or more light sources of a second sensor based on the amount of ambient light detected by the first sensor, wherein the second sensor is disposed at a lower part of the body and includes the one or more light sources and one or more detectors;
• emitting, by the one or more light sources of the second sensor and based on the adjusted current, light toward a body part of a user when the wearable computing device is worn by the user;
• and
• receiving, by the one or more detectors of the second sensor, a reflection of the light emitted toward the body part to generate a signal indicating a biometric of the user.

A non-transitory computer-readable medium which stores instructions that are executable by one or more processors of a wearable computing device, the instructions comprising:

• instructions to cause the one or more processors to receive information indicating an amount of ambient light in a surrounding environment of the wearable computing device detected by a first sensor disposed at an upper part of a body of the wearable computing device;
• instructions to cause the one or more processors to adjust a current supplied to one or more light sources of a second sensor based on the amount of ambient light detected by the first sensor, wherein the second sensor is disposed at a lower part of the body and includes the one or more light sources and one or more detectors;
• instructions to cause the one or more light sources of the second sensor to emit, based on the adjusted current, light toward a body part of a user when the wearable computing device is worn by the user;
• and
• instructions to cause the one or more detectors to receive a reflection of the light emitted toward the body part to generate a signal indicating a biometric of the user.
