Problems solved by technology

[0005] Invention patent: a sensor circuit for a liquid level meter (invention patent authorization specification CN200920165292.9), the designed circuit adopts a dual-processor structure, that is, the data communication and data sampling circuits are designed separately, and the clock frequencies are 1.8432MHz and 20MHz respectively. Data communication uses a low-frequency working clock to reduce power consumption. Data sampling works at a high frequency, and the working time is extremely short. Generally speaking, the power consumption of the traditional liquid level meter is further improved, but because it is responsible for the processing of data communication The converter is always in a low power consumption state, coupled with the conversion efficiency of the power supply, there is still room for further optimization in terms of low power consumption
