Πληρωμή κατά την παράδοση
I am looking for support in designing a prototype product. In summary, I require a standalone (battery powered) unit that has the ability to take readings of weight (from to 0-2.5kg) and send the data on a daily/weekly schedule via SMS/Email/upload (End point to be a google doc spreadsheet). The unit will need to utilise a SIM card or similar as its location will be in remote areas. The unit will need to be able to run for up to two weeks on a single battery. The unit will be of a very small size. If the end prototype is in line with requirements then I would like support/advise in how to manufacturer on a larger scale (initially 500 units then potentially 6000). Due to the usage of these units, the cost price per unit is a very important factor, therefore I will require estimates on price per unit. If you would like more information regarding the project, then please feel free to contact me.

Dear Sir, We have completed Electronic projects in Freelancer.com using WiFi, Ethernet, USB, Bluetooth and RS232 communication methods using Microchip, Atmel (Arduino Platform, Atmel studio), Texas Instrument and freescale ICs. We have completed 2 custom HID Device Projects recently. Please see our profile for more details of our past projects and current projects. We are currently doing project on MySQL Database direct interface with Arduino for passenger counting . We have Experience on PCB design and Manufacturing process with MLF packages with Chip antennas. We will introduce Manufacturing and PCBA companies with low cost with high quality. Our Design Idea on your project. It will be a Microcontroller controlled low cost GSM data system SMS and GPRS data will send to server at given time period Settings (Date/Time, data frequency ) can be upload via PC Program. Prototype cost will be around $80 Mass production unit cost will be around $35 Waiting to talk more about your project.. Then we will be able to fix Milestones and Timeline. Best Regards, Lasantha Prasad

Hello, i can help you. i have already developed the similar product that uses GSM MODEM for data communication. Following were the Characteristics of the system. 1. Gather Data from 80 temperature sensors in a building, installed at different Locations (sensors were LM35). 2. Gather Data from 3 Humidity sensors (sensors were SHT75). 3. Adds Date and time stamp. 4. Copies the Collected Data (Temperature+Humidity+Date and Time) in an EEPROM 5. Sends the Collected Data (Temperature+Humidity+Date and Time) to a remote PC via SMS through a GSM MODEM. The Remote PC was interfaced with another GSM MODEM that reads the SMS, fetch outs the Required Information and uploads the data to a web site. in your case we need to measure the weight instead of temperatures and humidity. i hope my previous experience will be beneficial for your project development. If you wish i can show you online working of my Project. Regards.

Hi Dear, I am an expert with more than 10 year of experience in the field of embedded systems, programming, electronics and signal processing. I have worked on architectures like 8051, PIC, AVR, MSP430 and ST. I have hands on experience in fields of smart metering, GSM/GPRS based meter communication and RF communication. I have checked the details of your project and happy to learn that I can help you in developing a low cost, small form factor and reliable product for you. In addition to this, I have been to china many times and I have contacts with suppliers that can help us make a low cost product. The idea is to have the following parts. Electronic load cell (as a linear sensor to the weighing machine) A local display unit (LCD or LED). Low cost GSM module (may be SIM900) MCU to control the overall function The terminal software (working as a server) to be able to collect data from GPRS (internet) or SMS * We can use SIM548 which is a GSM/GPRS/GPS module to locate the position of our weighing scale. I have all the development tools related to MCU and I would source the parts my self. I would deliver you 2 working prototype boards within 30 days along with complete Schematics, PCB layouts, Source codes and PC Software (if required) Regards Chaudhry

Hi: I made hundreds of patent product before. The processing steps is like this: Confirm the product function----> Ipression drawing with the funtion description----->Purchasing components, and design the product structure, and design the electronic part at the same time----->Strucuture prototype and PCB prototype-----> Pre assembly, Inspect product and Improve product design----->Make prototype again, and experiment the product----->Till OK----->Mold making----->Package design----->Production ---->Delivery. If you have interests, we can talk details on skype: meinvexcellent David
