Want to build a PC: Project is a height measurement tool based on arduino and ultrasonic sensing. Accurate measurement of the exact height of any object or product in the industry is very important and critical for maintaining the quality and desired functionality. Based on the above principles, It is user friendly and just needs to put the object in the box. Other measuring tools :(i) It is possible to measure a compressed object with some common distance or height measurement tools (such as Venire caliper), and at the same time measure a compressed object or a soft object, we get an inappropriate measurement, because all measurements have the chin of the extruded object. However, in the case of a sonar height meter, there is no Gripper to compress the object, so we can accurately measure the distance or height of the object in which it can be compressed. (ii) Special skills are not required: Most height/distance measuring tools such as Venire calipers, screw gauges, etc. measure the height of the object, and measuring the object accurately and accurately requires some special skills and experience. But it\'s very easy to use a sonar height meter, you just need to put your object in it. (iii) Improvement of movement and accuracy: precision ultrasonic sensors can measure the height of objects more accurately than other common height measurement tools such as Venire calipers, screw gauges. (iv) Get more information quickly: I recycled an old shoe box. 2. Electronic components U \"(in the program) If you get irrelevant results, check to see if there is any wire loss. version 2.
