Top 5 automotive hall efffect sensors for modern ADAS and EV cars

Irrespective of driving automation, and other advanced operational automation in automotives, there are lot of sensors required to ensure normal operation, safety, reliability, and maintenance of automotives. Along with various other sensors used in cars, Hall effect sensors are gaining importance for monitoring the health of the vehicle , as well as for safety and driving automation. Since Hall effect sensors operate contactless, they are reliable, and can withstand harsh automotive weather conditions. However due to the complexity of manufacturing, these sensors are yet to be commoditised and cost optimized. In this article we try to list top five hall effect sensors in automotives for various applications: 1. Graphene Hall effect sensor by a new company called paragraf: A thin coat of Graphene over hall effect sensor does magic in terms of sensitivity and avoiding stray magnetic fields. Though detailed specification are not available for this company's part named PG220505_GHS-series. However the brochure lists out various advantages of this product over non-Graphene Hall effect Sensor. This cost saving devices operates accurately under Ultra strong magnetic field, withstand high levels of gamma neutron radiation, and very high temperature and also at cryogenic temperature. Due to precise magnetic field measurement, can offer highest sensitivity...
