The Hall effect has a history of over a hundred years, but it has not been significantly applied until the last thirty years. The first practical application (outside of laboratory experiments) was as a microwave power sensor in the 1950s. With the large-scale production of semiconductors, the application of Hall effect in mass production has become possible. thatAdvantages of Hall Effect SensorsWhat is there? Miniature switch sensing and control revolutionized the keyboard industry by utilizing the Hall effect in 1968 with the introduction of the first solid-state keyboard. For the first time, Hall effect sensing elements and their related electronic components were combined in an integrated circuit. Nowadays, from computers to sewing machines, Hall effect devices are widely used in many products, including machines, cars, airplanes, machine tools, and medical equipment. Our current sensor is a relatively obvious Hall effect sensor.

Weikewei has developed a small test PCB that can not only complete two multimeters, but also achieve amazing accuracy and flexibility. With it, you can measure high or low side DC current, bus voltage, and have it automatically calculate power. It can achieve this with an accuracy of over 1% over an impressive range of voltage, current, and temperature, while transmitting data through I2C in an easy-to-use format. This core is the Hall effect current sensor. If you need it, please contact the technical personnel of Weikewei.
