Overall plan of this project is to modify a wireless weight scale to transmit data wirelessly to a database on a server.
Plan to use a commercially available electronic weight scale with serial data output such as

or equivalent.
I imagine will need a combination of off the shelf wifi transmitter with instruction coding on flash eeprom or similar.
Server-side software development is not included in this project request, unless bidder has significant experience to provide this as well and payment will be adjusted accordingly.
Some parameters of this project is certainly up for discussion if bidder has other plans to achieve same goal.
Hello, We are an Electronic Design House based in Pune, India specializing in Prototype Projects and Design Documentation. We have a strong technical team that specializes in Embedded Hardware , Firmware and PC Based Software. We bring to the table strong design and documentation skills. We can understand the design and document it as per user needs. The engineers are extremely fluent in English and working with them will not be an issue. Development work gets done in India and we have a sales team in West LA. We have an excellent network connectivity, VOIP setup for direct communication with US/European/Middle East clients. We will be able to work on this project. We will be able to work on this project. Cost of project will be $1500 and it will be completed in 50 days. BOM and PCB costing separately. This is tentative schedule from our side. If you have any plans in your mind then that will be followed and accordingly executed. We can provide references whenever required from US, India and Japan. Please let me know if any other information is required. Regards, Yogesh
Hello! I'm an experienced electronics engineer / programmer and would be pleased to work on this project. I have developped several connectivity solutions in the past and interfacing with a scale would be "easy" to do. I have most of the hardware already in hand (but the scale) so development could start faily soon.
I am a communications engineer, and work for several large government and public businesses. I build and install wireless products just like this. From RS232, RS485, Wifi, Bluetooth, fiber optics, ethernet, and everything communications related.
dear sir, i could solve your problem using polling method. so server side will be do polling to read the scales (if you use several scales) and then posting to the database. my bid is for equipment connecting your scale (1 pcs) to your pc with wireless. i will give all the configuration for this system, so you could do a test read you scale. but for the protocol for the scale depends on brand.
thank you
