The invention relates to the technical field of current sensors, and discloses a current detection circuit based on a Hall current sensor. The current detection circuit comprises a power supply moduleand a detection module, and the power supply module supplies power to the detection module; the detection module comprises the Hall current sensor, a signal adjusting circuit and a microprocessor; the Hall current sensor is used for generating induction signals according to detected current signals; the signal adjusting circuit is used for adjusting the induction signals generated by the Hall current sensor into analog signals capable of being matched with the microprocessor; and the microprocessor is used for converting the analog signals into digital signals and is used detecting the magnitude of the detected current signals according to the digital signals and outputting the detected current signals. According to the current detection circuit based on the Hall current sensor, the to-be-detected current can be conveniently and rapidly detected, the detection cost is greatly reduced, meanwhile, the circuit structure is simple, the reliability is high, and the problem that the detection result is easily interfered in the detection process is also avoided.

Description

technical field [0001] The invention relates to the technical field of current sensors, in particular to a current detection circuit based on a Hall current sensor. Background technique [0002] The current sensor is a detection device that can sense the information of the measured current, and can convert the information sensed by the detection into an electrical signal that meets certain standards or other required forms of information output according to certain rules, so as to meet the Information transmission, processing, storage, display, recording and control requirements. [0003] Current sensors are also called magnetic sensors, which can be used in household appliances, smart grids, electric vehicles, wind power generation, etc. Many magnetic sensors are used in our lives, such as computer hard drives, compasses, and household appliances. When the existing current sensor detects the current, the voltage signal or current signal needs to be digitally converted by P...
