Ultrasound cannot be heard by humans as the human ear does not pick up frequencies above 20 kHz. Some animals, including dogs, dolphins and some insects can hear ultrasound. Bats have the best hearing capabilities as they not only hear ultrasound but they also generate it and can determine their location from the echoes. Ultrasonics is used in a wide variety of technical and medical applications. Echo Sounding The echo depth sounder is a device that uses the reflection of sound or ultrasonics to determine the water depth. The depth sounder determines the depth. | Education Programme The Ultimate Driving Machine BMW Young Academy In-car Technology Lesson 1 Automotive Sensors Student Workbook Jointly funded by the Quality Improvement Agency and BMW UK Ltd Education Programme The Ultimate Driving Machine About Young Academy Discover the skills needed to work in the automotive industry and learn about the science and technology behind the cars with Young Academy BMW Education s online resource for 14 to 16 year olds. Young Academy is a series of lessons based on BMW Academy s own award-winning apprenticeship programme. By working through the lessons you will take a journey from learning about the principles of electrical theory to developing an understanding of the skills and knowledge needed to become a motor industry technician. The Young Academy lessons are available from the BMW Education website at Academy This information booklet has been provided as an accessible alternative to the interactive lessons. About In-car Technology Lesson 1 Automotive Sensors When you are in a car you might not realise that you are surrounded by sensors - in the seat belts the car doors and the rear view mirror to name a few. Sensors respond to physical or chemical triggers such as pressure temperature or distance and convert them into an electrical signal. In this lesson you will explore different types of sensors and learn about four areas that use sensor technology including parking distance control digital compasses night vision and car temperature regulation. At the end of this lesson you should be able to Describe the operation of a Hall sensor Describe the operation of an inductive sensor Describe the operation of an ultrasonic transducer Explain the operation of the digital compass Explain the operation of the night vision system Describe how coolant temperature sensors work 2 Lesson 1 Automotive Sensors Overview Objectives Introduction Page 4 Park Distance Control .
