Collision avoidance sensors provide analog proximity measurements for various collision occurring hazards. Collision avoidance sensors are used to prevent collision of automatic guided vehicles with either to some other vehicle or person moving on the road. A proximity sensor is mounted either in the front or at the back of automatic guided vehicles. Collision avoidance sensors start working as soon as the vehicle engine is started and the vehicle starts moving. An anti collision sensor works on ultrasound technology. An ultrasound anti collision sensor mounted on the vehicle continuously sends and receives sound wave signals from and to the moving object. The sound waves are sent to detect any colliding object appearing on the way of the moving object. As soon as a colliding object is detected in the range of 8 feet, the driver is warned with an alert sound and the driver can take the appropriate action. There are many different types of collision avoidance sensors. Examples include a parking sensor and a radar proximity sensor. A parking sensor is used in automobiles for safely parking the vehicles in the smallest possible space. A parking sensor can also easily detect objects that are out of vision range. A radar proximity sensor is a speed sensor that is used to measure the speed of the vehicle. Other collision avoidance sensors are commonly available.
There are several ways in which collision avoidance sensors function. Collision avoidance sensors send infrared collision detection signals in the form of ultrasonic radio waves and on colliding with some object sends back the signal to the proximity sensor radar. A proximity sensor radar alarm generates an alarm, which notifies the driver to take an action. A parking sensor consists of a central control processor, a digital display and buzzer, and self-adhesive sensor. A radar proximity sensor is a built-in LED sensor and should have a weather resistant connector. A radar proximity sensor can measure speed ranging from 0.3 to 37 miles per hour using an infrared collision avoidance system. Collision avoidance sensors are designed and manufactured to meet most industry specifications.
Collision avoidance sensors are used in many applications. Collision avoidance sensors are widely used in automobiles, such as buses, cars, trucks, and hazardous machines. In addition, collision avoidance sensors are also used as a protective system in robot arms and docking bays, and as a safety system in automatic shelving.
