Description

technical field [0001] The invention relates to the field of data acquisition, in particular to a clock chip-based low-power data acquisition and transmission system and an implementation method. Background technique [0002] Data acquisition refers to automatically collecting signals from sensors, as well as analog and digital units under test, and sending them to the host computer for analysis and processing. The collected data are various physical quantities converted into electrical signals, such as temperature, humidity, water level, wind speed, pressure, and RFID information of materials, etc., which can be analog or digital. Today, with the rapid development of the Internet industry, data collection has been widely used in the Internet and distributed fields, and important changes have taken place in the field of data collection. [0003] For many occasions where power supply is inconvenient, battery power supply is required, and power consumption control is an essen...
