Design me a Product

hi sir we are professional engineer i have read your requirements they project budget you proposed is not enough i have placed an efficient design budget i can assure you professionally designed product please reply to discuss it further regards

Hi, I have several years of advanced experience in arduino development and 15+ years in electronics/embedded development. What I propose using in your project: - Arduino UNO R3 - SIM900 GSM/GPRS shield - DS18B20 temperature sensor General behavior: - phone number to send SMS and temperature threshold stored in arduino EEPROM - main loop is always reading sensor temperature - if temperature is below threshold value, attempt to send SMS alert to stored number -- if number is stored in EEPROM, send SMS -- if number is not stored in EEPROM, do nothing - if SMS is received and sender number matches stored number, interpret commands - if command is "TEMP xxxxx", change temperature threshold to new xxxxx value - if command is "PHON xxxxxxxxxxx", change phone number to xxxxxxxxx value - serial commands to show debug info and program both temperature threshold and phone number through arduino serial port (initial programming and in case of wrong phone number programmed or changed, etc.) Please let me know if you are interested and feel free to contact me for additional info. Best regards, Carlos.

Hello. I have good experience in SIM900 modules and Arduino. Can make that project for you. Please, write me in chat if you whant to discuss some details

Im qualified electronic and telecommunication engineer and very familiar with Arduino. I can do the job for you.

ACTUAL BIDDER! NOT A SUBCONTRACTOR!!! I have a very similar project already done. Hello, i have a PhD in Mechatronics and ample experience with Arduino boards, as well as microcontrollers. I have most of the hardware needed to get this started and have worked on many projects before and i can provide proof of those projects. Please contact me or view my profile for further reference. Best regards

Hi, I've the project ready with me. I can deliver complete project firmware, schematic and document. Looking forward to work with you /Venu

I have extensively worked on GSM modem and arduino. This project can be completed in 2 days, but just for the record on Freelancer, I have started 4 days. you can message me if you feel like confirming any more details before closing the bid.

Dear Sir / Madam, I am new to Freelancer.com, but I have a lot of skill in programming and hardware design for data acquisition systems, mainly in water. My master's thesis was the implementation of a network of wireless sensors for monitoring and controlling water quality of aquaculture ponds in the company Caviar Portugal. Although the system to be monitored in a different environment, a major facings for the evolution and reproduction sturgeon is the water temperature. The hardware solution used for my master's thesis consisted of ATMEL328 (Arduino IC) for the acquisition, XBee modules for data transmission and GSM / GPRS modem to alert transmission. I'm currently working on a hardware development company, but I can work about 4 hours a day with your project. I promise to deliver a complete and tested solution for your project and only after satisfaction on your part, agree to appropriate remuneration. If chosen for the work we discuss the main points of the project in order to define a more precise deadline for completion of the work. Kind regards Daniel Pozzatti

Hello, I think I can provide a quick solution for what you need I'll only need the specs of the temperature sensor and I'll handle the rest; if you want I can pick the sensor for you. I'll provide: Eagle Schematic Files and Gerber for manufacturing Firmware BOM Assitance in order to put the project together on your end and troubleshooting if necesary Best Regards, Brayan M

I am very experienced when it comes to arduino. I have made a lot of autonomous robots working on arduino. I might to new to freelancer but definitely not new to arduino. I understand your needs specifically and I even understand that you would need a full description of how to set it up. Don't worry I would make it in such a way it would never be a problem to set it up. I am from IIT Kharagpur. I am currently in the Robotics Society of IIT Kharagpur. It takes a lot of knowledge and effect to shine among IITians.

Hello, I can do this project for you on an AVR + no shield, instead using parts that are needed for the project. If you want a working prototype (could be final product) shipping and parts will be extra.
