We are looking for someone to assist with designing an ultrasonic distance measuring circuit. The design is to be operable between 2.7 and 3.3V and must communicate with a microcontroller using a serial digital interface. We are looking for something similar to the HC-SR04 and similar modules readily available online, however we have requirements that do not allow us to use these off-the-shelf modules.
Please reply with your relevant experience or qualifications, so we can contact you to discuss further details. Thanks.
