Ultrasonic Ranging Module HC-SR04 provides 2cm-400cm non-contact distance sensing capabilities, Ranging accuracy up to 3mm. ultrasonic sensor are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for ultrasonic sensor. The DFRobot URM05 High Power Ultrasonic Range Finder is based on electrostatic senscomp's 6500 ultrasound transducer design. It can measure a distances of up to 10m. The angle between the ultrasound probes is only 15°, while the majority of the ultrasound is 60°. This post is all about the Ultrasonic Sensor HC - SR04. I'll explain how it works, show some features and share an Arduino Project example to help you with your projects. We provide a schematic diagram on how to wire the ultrasonic sensor, and an example sketch to use with your Arduino. Devantech SRF08 UltraSonic Ranger This Devantech high performance ultrasonic range finder is compact and measures an amazingly wide range from 3cm to 6m. The SRF08 interfaces to your microcontroller via the industry standard IIC bus. This ranger is perfect for your robot, or any other projects requiring accurate ranging information. Oct 31, 2017 · Ultrasonic Range Finder using 8051 – This project as the name says, is an application to measure distance of an object. It uses an ultrasonic transducer module HC-SR04 to measure the distance and the controller AT89S51 to make the necessary processing. The Devantech Ultrasonic Range Finder SRF04 will soon become essential for your robotic applications. Indeed, with this sensor, it is possible to know the exact distance of an obstacle in the sonar field of view.
