Need a prototype for a project. My needs are: Hardware * An Arduino based PCB * Two temperature sensors, preferably DS18B20 - The first temp sensor attached to a 1,1 meter long cable -The second temp sensor attached to a 0,2 meter long cable * A GSM shield, preferably SIM900 or other GSM shield that will work world wide * Re-chargable battery, preferably standard size AA * A battery holder * on/off switch * a box for all electronics * a micro usb port All those parts soldered and fitted in a box. No loose parts! Needs to be screwed into the box with temperature sensor hanging out and on/off switch easy accesseble. Software So, what should this thing do? Pretty easy. The sw should collect data from the two temp sensors once every 120 second and send the data in degree Celcius to thingspeak. The sw should be optimized to use a minimum of battery power. Some kind of sleep mode is needed. I should be able to insert my own SIM card and via the usb/arduino software enter the pin code. The source code needs to be well commented. I will review your progress. First to see your HW shopping list, second to see the HW build, third to se the product working (preferably via a video or skype) and after that you need to ship the product to me in Europe.

Hi, I have read your project description. I guess for all of those component including Box, I need budget about 100-150$ here. And I guess You will pay me for it. I will use acrylic box, Arduino Uno, SIM900 shield, and Proto shield in order to attach switch, battery plug, and sensor plug, which will be connected via cable you described to Arduino module. I didn't check shipping cost from Indonesia to Sweden. But I guess normal shipping would cost around 50$. My service cost is about 120$. So, the total budget for this project is about 320$. and usually freelancer.com charge me 10% of total project cost, so my total bid is about 350$. Let's start this project by chating me. Let me know if you have another suggestion about this project. let's discuss it. Best Regards, Rijal

Hello, Thank you for the Detailed Description. I have done a similar project with TWO DS18b20 temperature sensors with NodeMCU and Arduino UNO before that sending data on Thingspeak as well as on SD card with Alert email using IFTTT. In that project I have done the both PCB design and Software part. (IF YOU WANT I can show the pictures of PCB that the client to me after manufacturing). I have some question on PCB design Part that I want to discuss with you briefly. I understand the software Part but please confirm me Do you want to USE SIM900 to SEND alert on the phone when the temperature is reached at HIGH or for the only for internet purpose? If you want to send data on Thingspeak then I have to connect the WI-Fi module also. I can also send to you the working video of the project for your confirmation before to send prototype. I can also ship the prototype at your place but you have to pay the shipping charges. (Before, I have shipped the prototypes in the USA and in Thailand). I am always developing the prototype for my testing purpose but if the client wants then they pay me the component cost and I will send them. You have to pay me the component cost for prototype so, I can send to you. If any question you have for me please ask any time. Thanks, Chanchal k.

Hello! I'm an electronic engineer with experience in modified Arduino. I can help with this project. Y think an Arduino Uno based system with an Atmel 328p MCU could be ok. I propose you a board with a charger for an Ii-on battery which works with the USB plug or if needed we can put an external plug for a 12V source of power. The system could work with the battery or with +5V USB if plugged. The battery holder could be placed in the same PCB, so you have only one thing to put in the case. I don't know if you are thinking of a special case or it can be selected. If there is an only prototype project, we can think in a customized 3D printed case. My bid includes: - Hardware design - PCB design - Hardware sending for manufacturing. - Firmware codding Shipping cost, PCB cost and assembling cost are not included. If you want to design a 3D enclosure, the price is not included, and I do not do the work, but I have people to do that. When HW design in finalized, you have to deposit to me the funds to send to production or you can place the work in the PCB manufacturer and put my address. Finally, the project time is not accurate. It depends on the manufacturing process so we can see it on the road. Please feel free to ask me anything.

Hi, I did a very similar system, fits in a 7x5x4 cm box (excluding batteries) and already uses: Gsm module Arduino DS18b20 can be equipped with hardware watchdog PCB already available upgradeable OTA Moreover it provides a WEB interface to program the parameters from any pc/smartphone/tablet with wifi connectivity and an HTML5 enabled browser. I can show it by skype (I'm GMT+1) or if you provide an email I can upload the pics. I want to keep the price low because I would like to do such project since I never tried to work with thingspeak ! Perhaps you can assign the project to another freelance and have me in parallel, it would not cost you much and perhaps you'll get even a better result. Please consider that 10 days is a rough estimate. Cheers, Alex. p.s. The HW & material costs and the delivery expenses are not included in the bid, however I've no mark-up so I suppose is less than 100$ for delivery & parts. If you like I can 3d print your specific box.

Hi, I saw that you are looking for a developer to build a data logger using temperature sensor and sim 900 with arduino chipset. I can provide you that with complete project and ship you the project to Europe. I already own arduino and sim808 therefore I can start the work immediately till the sim900 and new components get shipped to me. I can work for you from today and I can submit you the project in time with no bugs at all. Contact me if you have any questions I will answer them asap. Thank you for considering me. Hope to hear from you soon.
