Lately, video game hardware manufacturers have been upgrading controllers with technology such as TMR and Hall effect sensors. However, the items are worth the price you pay because Hall effect sensors provide superior controls and are less prone to stick drift. The secret sauce behind Hall effect sensors are their reliance on electromagnetism, specifically a principle of magnetic fields that their namesake, Edwin Hall, discovered way back in 1879. This is what is known as the Hall effect. Since Hall effect sensors rely on magnetic fields instead of physical contact, they exhibit less wear and tear — the primary causes of stick drift.
