$250-750 CAD

Paid on delivery
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.

Hi, I have worked many distance sensors before for counter project. In my opinion there is better distance sensor than HCSR-04 coz it is too rude. I would prefer to use VLX sensor( World smallest Time-of-Flight (ToF) ranging sensor) but also it depend on your active distance area. All the BEST, Ali SERBETCI

Hello kindly i would like to have more info about the following points 1- Required Sensing Distance 2- Target Production Cost (Unit Cost) and at which Quantity 3- Max Size 4- Do you need help with the firmware or just the sensor 5- 2.7 to 3.3 is relatively low for such application , so i have to use boost converter to provide that range (Do you have any constrains on using Boost converters ?) About Experience I have been designing electronic products for more than 8 years , Low & High frequency applications but not this one in particular as it is already available in so many different classes I have very good experience and relations with many factories and suppliers which i tested and verified their quality over the years I can provide the following 1- Electronic Products Design Consultation 2- Up to date components Selection 3- Schematic , Layout (Proteus) and Gerber files (Production files) 4- BOM (Bill of Material) with a full supply chain of all items from trusted suppliers and with cost effective prices 5- Prototyping and Manufacturing Management , As I arrange whole process with factory and suppliers also shipping to your door If you have any questions feel free to contact me anytime Best Regards

Hello, I'm a mechanical and instrumentation engineer from Canada. I have extensive experience in designing and fabricating measuring systems for object detection, measure the dimensions, temperature, pressure etc. I'm proficient in Arduino, raspberry pi, PLCs etc. As you mentioned in the project description that you can't use off the shelf so I could make a sensor similar to HC-SR04 or URM04. If you require having a micro-controller from the scratch as well, I can use the ATmega 328P from the scratch or an alternative. If you would like me to send you the finished sensor and the microcontroller board I can most definitely do that for you and have it couriered to you as well. I would like to thank you for taking time to read this and I hope to hear from you soon. Please feel free to ask any questions or any queries you might have. Thanks
