Abstract
An electricity usage monitor may include a coupling component to attach the electricity usage monitor to an electrical circuit to monitor electricity usage of the electrical circuit, an analog-digital converter (ADC) configured to convert analog current readings captured by the electricity usage monitor into digital values, a processor operably coupled to the ADC, and a non-transitory, computer-readable medium operably coupled to the processor and comprising instructions which, when executed by the processor, cause the processor to perform operations. The operations may include determining a standard deviation of the digital values, based on the standard deviation, adjusting a gain of the ADC, and transmitting a signal to a server comprising the digital values.
Claims20
A method of electricity usage monitoring, comprising:
- receiving a plurality of readings captured by an electricity usage monitor;
- converting, by an analog-digital converter (ADC) of the electricity usage monitor, the plurality of readings to digital values;
- determining a standard deviation of the plurality of readings captured by the electricity usage monitor, based on the digital values;
- adjusting a gain of the ADC based on the standard deviation;
- and
- transmitting a digital communication comprising the digital values and the adjusted gain of the ADC.
A method of electricity usage monitoring comprising:
- receiving, by a server system, from an electricity usage monitor, a digital communication comprising readings captured by the electricity usage monitor converted into digital values by an analog-digital converter (ADC) of the electricity usage monitor;
- receiving, by the server system, an adjusted gain of the ADC;
- updating the server system based on the adjusted gain of the ADC;
- and
- decoding, by the server system, the digital values based on the adjusted gain.
