How an accelerometer type of airbag sensor operates?

An accelerometer-type airbag sensor detects rapid changes in acceleration that occur during a collision. It consists of a mass suspended within a housing that moves in response to sudden deceleration. When the vehicle experiences a crash, the mass shifts, triggering an electrical signal that activates the airbag system. This rapid response ensures that airbags deploy in a timely manner to protect occupants during a crash.
