The Transmission Interface Design of Hall-effect sensor

In order to adapt to the need of high sensitivity, high accuracy, high data transmission speed and low power consumption in Hall-effect sensor application field, a sensor microsystem including a high-precision Hall voltage sensor, a 24-bit analog-to-digital converter, a FPGA chip and a LCD1602 is designed in order to detect and display the external magnetic field strength in real time. In this paper, we discussed the hardware and software design of Hall-effect microsystem sensors in details. Finally, system debugging and performance analysis have been given.
