Automatically limiting power consumption by devices using infrared or radio communications
11289619 · 2022-03-29 · ·

Methods, apparatus, and processor-readable storage media for automatically limiting power consumption by devices using infrared or radio communications are provided herein. An example computer-implemented method includes detecting, via at least one photodiode of an emitting sensor, one or more signals output by a user device within a predetermined proximity; automatically transitioning, via utilizing at least one transistor connected to the photodiode, and in response to detecting the one or more signals, the emitting sensor from a first power-consumption state to a second power-consumption state; transmitting one or more signals in response to transitioning from the first power-consumption state to the second power-consumption state; and subsequent to transmitting, automatically transitioning, via utilizing the at least one transistor, the emitting sensor from the second power-consumption state to the first power-consumption state after a predetermined amount of time has elapsed during which no signals were detected.
