Hi, I read your bid and it is clear to me. I have experience with Arduino and XBee. I also have all of these modules available.

Firstly reply to your questions: What is your full name? Ans- AMAN KAUSHAL What is the Capital city of your home country? Ans- NEW DELHI (INDIA) How many years have you been working with computers? Ans- working with computers for past 6 years , working with arduinos , microcontrollers , sensors , xbee , gps , gsm for the past 4 years. I have worked with motorsports organisations and provided them end to end wireless(xbee &gsm) , gps based timing and logging systems .I have all the hardware ready with me , in fact i have done this kind of poject earlier . I have done my homework and research as well just waiting for you to award this project to me . Just trust and award this project to a newbie of reelancer .and FYI the project completion might happen in 3 days, kept 2 days spare for testing and debugging. Regards Er. Aman Kaushal

Sir I am an experienced freelancer having Bachelor and Masters in EEE (Electrical and Electronics Engineering), now working as a lecturer at DUET..... It is a very easy project for me..... I promise you perfect completion of this project within the shortest possible time.... Please check my reviews and the attachment to judge my quality.... Let us commence at once... thanks Ishtiak

I have 13 year experience in electronics;Am very much interested your project, kindly send me more information regarding your requirements. About my self , you can review my profile and my clients comments. How you can going to check the software? Thank.

Hi, I have experience with Arduino and I can do your project. What is your full name? Slavi What is the Capital city of your home country? Sofia How many years have you been working with computers? 25+ Thanks.

Hi Matthew. Im Greg. Im Telecommunication engineer. I can help you with this project. Ive worked with a lot of similar projects (also i can programm directly from datasheet). Message me and we can discuss deadlines and prices. Regards.Greg.

I have working with Arduino projects the last four years. The type of work described by you is within my skills. I am very interested to assist you in your development needs. 1. My name is Luis Mario Mendoza Segura. 2. Mexico 3. I've been working with computers more than 20 years.

Hi. I am an experienced Electronics Engineer having 5 years of experience in Micro-Controllers and in XBEE projects. I have seen your project's pdf file completely and i am very happy to see that i can do this work for you with quality and in minimum time. Let me do this task for you. Contact with me for further details, so that we can go for this project together.

Hi, I've worked on several projects, including a quadrotor. I think the job at hand is fairly simple: I need to program both the Arduinos, one to transmit the data corresponding to the gases, and the other to receive the data, interpret it, and based on that, send communication to the computer. I can set it up such that you can partially program the receiving Arduino from the computer quickly. <adjusting thresholds, etc> I look forward to this project. Please contact me if interested. Regards, CB.

Greetings. My name is Jeremy Trammell and I represent a group of developers and designers in Portland, Oregon. We have extensive experience with the Arduino platform, and with Windows application development, and we would be happy to assist you with your remote gas sensor project. We would require a 25% down payment to cover our tooling expenses (ensuring we have the same hardware that you have) and the remaining 75% upon completion of the work. The capitol of the U.S. is, of course, Washington D.C., and we have been in business for over a decade. Please let me know if you have any questions.

We are professionals in hardware development and embedded systems using microcontrollers in C/C++, and FPGA/CPLD using VHDL esp. for Xilinx. with 9 years experience in MCUs and FPGA. Also PCB design and manufacturing using Altium Protel DXP. We can also develop embedded system using Arduino, Netduino, and Pcduino boards and MS .Net Micro Framework. We promise you with very high quality product and on time delivery. Samples are on our portfolio page of profile page on http://www.freelancer.com/u/usamacpp.html. Regards.

Ready to work and use my 35+ years experience with microcontrollers. As per your request : What is your full name? Pablo Martin What is the Capital city of your home country? Washington DC How many years have you been working with computers? Im working with microcontrollers from 1976 ( the old 8080) Lets talk about your project , i got some ideas. Regards, Pablo

My full name is Hoang Tran. I'm living in Ho Chi Minh City, Vietnam. Ha Noi is capital of Vietnam. I have more than ten years experience in embedded system and computer, and has experience with kind of your project.

Hi, I'm interrested in your project as it fits my formation in Computer engineering and because I realised many projects with arduino in the past. I was the electrical manager or alerion supermileage team, a fuel economy prototype that hold the North American record of 3500+mpg so I am used to work with microcontroller and sensors. I also did many PCB design that can work in real life environnement and that were made to be used by many other people in the future. I really do freelance for fun and to work on interesting project. You wont have any problem with me as I document all my work and I like to do really clean programming. I'm also a fan of test driven developpement (TDD) so all my work will be tested and the final product will be easily modifiable since the test will provide assurance that the prototype works. I am also flexible on the rate and the devlivery. I would like to do cooperative work with you so you wont be disappointed with the result, I want to make sure you understand fully the final product and that it's up to your expectation. If you want more information about me or my past project, feel free to ask by email. Thanks for taking your time and I hope to work with you :) Louis-David

Hi, I am Firmware programmer. Have strong command over controller programming. What is your full name? Name: Dhaval N Patel What is the Capital city of your home country? Capital: Delhi How many years have you been working with computers? With Computers: 8 years

There's no actual need to use such a complex and expensive set of apparels. In case of prototyping, it could be even acceptable, but if you're going to production then you should keep in mind some major facts: - Arduino, despite its simple set of features, is much more energy hungry of other ARM-M0/3 based platforms - If you adopt ZigBee as transmission medium, then your coordinator node should be wiredly connected to a central networking system, but you haven't any networking on the central Arduino - Different systems like Bluetooth low energy and/or Wifi could extend your communication range and keep each of your nodes both coordinator or standalone, as any site would share the same set of features of the others. - ZigBee is by far more expensive of 802.11b/g/n SPI or UART Wi-Fi modules, which can already offer the basic TCP/IP stack and SoftAP features: in practice for any production purposes ZigBee is a nonsense. Just my two cents, I can propose something low-cost and much more feature proven by integrating a STM32 Value Line product (less than 1.00 USD per 1K pieces.). I can handle the whole project, from schematics to PCB and firmware. I set up the bid just for capturing your attention. Short answers to your mandatory questions: - Full name: Mario Vigliar, PhD - Country: Italy - Capital: Rome - My experience with computers: since 1987 (enough???) Waiting for your news, Ciao, Mario
