Mainly inertia switches are used to detect the accident and cut off the fuel pump. I think separate sensor is used for operating air bag in the vehicles
They use inertia switches.
Magnets are used in cellphones for various purposes, such as the speaker and microphone to convert electrical signals into sound waves and vice versa. They are also found in the vibration motor for notifications and in some cases, as part of the compass sensor for orientation detection.
An IR sensor in a robot can be used for various purposes such as obstacle detection, line following, distance measurement, and object detection. The sensor emits infrared light and detects the reflection to identify the presence or absence of objects in its path, allowing the robot to navigate its environment effectively.
its only detection part like sensor but commonly used in liquid phase only.
Used for error detection
An infrared-dependent resistor (or IR sensor) is a device that changes its resistance based on the intensity of infrared light it detects. These sensors are commonly used in applications like motion detection, proximity sensing, and object detection where the presence of objects can be determined based on infrared radiation. The resistance of the sensor changes based on the amount of infrared light detected, allowing it to be used in various electronic circuits for automation and control purposes.
There isn't a single best sensor for detecting objects as it depends on the specific requirements of the application. However, commonly used sensors for object detection include ultrasonic sensors, infrared sensors, and LiDAR sensors, each with its own strengths and weaknesses. It's essential to consider factors such as range, accuracy, cost, and environmental conditions when choosing a sensor for object detection.

A proximity sensor is used to detect the presence or absence of an object without physical contact. It emits electromagnetic fields or beams and measures changes in the field to determine the distance of the object from the sensor. This technology is commonly used in smartphones, automotive parking sensors, and industrial automation for object detection and proximity measurements.
