Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to a data acquisition system based on Bluetooth 4.0 technology. Background technique [0002] Data acquisition is about collecting physical quantities in the real world and converting the collected physical quantities into electrical signals that can be used for calculation. Data acquisition systems usually convert analog quantities into digital quantities. Data acquisition connects the computer and the real world. Together, it is a very important way to obtain information. With the continuous development of society, the demand for data collection is increasing. With the increasing complexity of planning in buildings, the data collection system must follow the trend from traditional wired transmission Upgrading to wireless transmission requires encrypted transmission due to the privacy of data. Among the common wireless communication technologies, the technology that can me...
