What sensor is responsible for deploying airbags in a vehicle?

The impact sensor is the component specifically designed to deploy airbags in response to a collision. When a vehicle experiences a sudden deceleration or impact, the impact sensor detects these changes in force. If the force exceeds a predetermined threshold, the sensor sends a signal to the airbag system to deploy the airbags, ensuring the safety of the occupants by providing cushioning at the moment of impact.

In contrast, other sensors like pressure sensors and temperature sensors do not play a direct role in airbag deployment. Pressure sensors typically monitor systems such as tire pressure or fluid levels, while temperature sensors track the temperature of engine components or other systems but do not relate to crash dynamics. Although "crash detection sensor" may seem appropriate, it is a broader term that can encompass various types of sensors and does not accurately point to the specific sensor that triggers airbag deployment. Thus, the impact sensor is the most accurate answer to identify the sensor responsible for deploying airbags in a vehicle.
