Hi, I need two existing circuits to be altered to accommodate different (given) transducers (and hence different frequencies). You are free to either completely redesign the circuits or simply change the values of the components of the existing circuits to accommodate the new transducers. The circuits and the current approach are described here: [login to view URL] Circuit 1 drives a given ultrasound transmitter via an arduino uno board. Circuit 2 amplifies the signal of a given ultrasound receiver so it can be read by another arduino board. The datasheet of the new transducers can be found here: [login to view URL] please note that transmitter and receiver are two different units. Best, Patrick

Dear i can help you. can you specify the desired frequency at which Ultrasonic should be modulated? secondly the ready made modules are also available for range finding.i recently built the water level indicator using ultra sonic range finder. Please feel free to contact. Regards.

I am an engineer and inventor with a penchant for interesting designs. While looking through Freelancer I found your project to be interesting. Are you looking to be able to send and receive data through the transducers, distance measurement, etc? Anything is possible, and I would be happy to help you with your application. I excel at post support, and making sure your application works on your hardware the way you expect it to. I am available on Skype as well as cell-phone for US clients. Sincerely, Charlie Sperbeck

I have some experience with ultrasonic transducers. Specifically, about 10 years ago I designed and manufactured an ultrasonic range sensor with transducers similar to that presented in the project you want to modify. I am looking forward for an answer from you. Calin

Hello :-) I am working in R&D departement in robotics company as an electronics and programmer. Just now I am implementing in my robotics system ultrasound sensors. I use something a little bit different that you wrote. My robot has 6 sensors so for embedded system it is better to communicated with separate ultrasound sensors throw I2C interface. Anyway I am in that field an expert and can advice you in that field. Best regards! Electronigence
