Silicon Labs (also known as "Core Technology") recently released a widely combined Hall Effect Magnetic Sensor series product, Si72xx, for applications such as on/off detection, further providing excellent solutions for the design of position sensing applications in various industrial or consumer IoT products.

The Si72xx Hall sensor has industry-leading detection sensitivity and energy-saving benefits, which can improve the battery life of the device and expand the sensing range. Due to the stronger sensing ability of Si72xx, the size and cost of the magnet can be reduced, promoting loT products to be more cost-effective. It is worth noting that the new Silicon Labs Hall sensor also incorporates many advanced features, including I ² C has configurable functions, damage detection, and built-in temperature sensing functions.

Principles and application fields of Hall sensors:

Hall sensor is a magnetic field sensor made based on the Hall effect. The Hall effect is a type of magnetoelectric effect, which was discovered by A.H. Hall (1855-1938) in 1879 while studying the conductive mechanism of metals. Later, it was discovered that semiconductors, conductive fluids, and other materials also have this effect, and the Hall effect of semiconductors is a basic method for determining the performance of metal semiconductor materials. The Hall coefficient measured through Hall effect experiments can determine important parameters such as the conductivity type, carrier concentration, and carrier mobility of semiconductor materials.

Based on the principle of Hall effect and combining its excellent CMOS process and energy-saving chip design knowledge, Silicon Labs has created a low-power, high sensitivity, and industry-leading flexibility and programmable Si72xx Hall sensor, providing an ideal solution for various LOT devices that require sensors to detect changes in on/off position, such as industrial automation systems and smart home appliances.
