We need a device that can monitor 3 separate low level DC voltages (0.5VDC low to 1.9 VDC high). When the voltage changes from one level 0.5 VDC to the other 1.9VDC we need the device to communicate to a local computer/internet gateway the state change which will then send a text/email to the user that the state has changed. 1. Can this product be sourced? 2. What are the steps involved in making it a reality? From prototype to finished product and manufacture? 3. Approximate costs involved in doing this? We are ready to fund this project and look forward to speaking with you!

Hi, I am an Electrical Engineer and I also hold Masters degree in Computer science from top-ranked universities in Pakistan. I had developed a very similar project for one of my professors which basically involved sensing of humidity in atmosphere and sending the data to an attached computer which would plot the results in a centralized database. Coming to your project, since you need to make it a product at the end so the cost effectiveness is a must issue before arriving at any feasible solution. Using embedded controller for this project not only will add to the cost but also this project is not that complex. Using PIC micro-controller is the answer. An analog to digital converter is built-in this controller which will translate the voltage levels into digital signal. The controller will be programmed to keep an eye on the voltage levels. And whatever threshold you set, the controller will react to signal the computer via USB interface (built-in this controller). On the computer, an application built using C# Sharp .NET will react to the incoming signal from the USB interface and there we would program it to connect to the server for sending email or text. Sending email is trivial, but for sms, we would not to subscribe for some SMS sending company, using their API. I will not only provide you with all the source code, programs and instructions but will build the micro-controller circuit with full interface and will ship it you. There is no more space left for message

Good day! I am interested in your project and I can get this done for you better and more neatly than anybody else here. Anyway, please NOTE that i am going to need upto 30 days to complete this work. I would like to properly schedule my work load so it would be easier for me if you could kindly let me know of your deadlines. * When do you need a working prototype? * When do you need the final product? * Do you expect me to manufacture this in large quantities (I do not have the facility to do so in large quantities even though I should be able to do it myself if its not more than 100 units or so. Anyway, I can find a manufacturer who can do it for you without any problem, once i have made the a working a prototype and a final product) * There are not many steps involved in this. I would simply put the stuff together in a breadboard and write the code and get a working prototype ASAP and then once i got your approval, I can properly put together 1 unit for you to test out. Mass manufacturing would be based on how many units you need produced. * Without adding my labor cost/etc, i should be able to produce a unit at a hardware cost of around US $15-$20 (or less if made in large quantities). (I made this estiate assuming that you would like an ethernet connection to a PC, router, etc) Please note that this bid is for 1 working unit and it may subject to change once I have a more elaborate description of the project. Thanks! Alex

I have +10 years of experience in High level programming. I am not electrical engineer. Your work have 2 parts. 1. Detect voltage and sending some thing to serial or usb port of computer. 2. Monitor serial or usb port to see commands from device and send email to end user. First part can be done by standard Oscilloscopes or manually made ones. I am not expert in this field, but seems simple. I am expert in second part. It is too simple too for a high level programmer like me. I have many projects working with serial ports and also sending automatic emails. I think it is better idea to make these 2 parts separate. Because electrical engineers are not expert in high level programming and high level programmers are not expert in electrical engineering. I can do second part for you just with $400 if you can find some one be able to do first part for you. Regards

Dear Sir, We have completed several GSM based projects as well as USB and Ethernet custom devices for data logging and interfacing with other external devices. We have capability to deliver best quality prototypes with minimum cost. Please see our profile and portfolio to see our past projects and feedbacks. we can do following options to achieve your project requirement. Hardware : Option 1. Hardware will monitor the voltage of 3 separate connections and communicates with local PC via USB connectivity. All voltage data will display on PC Screen and data logging part also possible (we can write excel file as data table with date time ). When State change occurs device will send text message to indicate the state change. Option 2. Hardware will monitor the voltage of 3 separate connections and it connects to Ethernet Switch or Router. Device has Web Sever facility and user can see the current status of voltage by login in to web server by using any computer on network or via internet. When State change occurs device will send email to indicate the state change. Software Stand alone software will be developed for Option 1 to communicate with the device. All above suggested features will be able to add your project. Please contact us for more details as well as videos of our past projects. Best Regards, EEmbedded Team. hello sir, waiting for your reply. hello Sir, contact us for more details..

I'm an engineer with 17 years of experience. I have designed similar solutions in the past. I can design the hardware and provide you with the software end support as well. We will need to do a POC. For this POC, the hardware may be a bit bulky as it will essentially be put together just to get it working We can then determine the issues faced and iron them out. Once we have a complete solution in hand, we can work out final production costs per piece based on volume. Thanks,

Hi, I can provide you full project with complete hardware design (schematic with AVR microcontroller, test PCB -manually manufactured and tested) and software program (as a Labview executable-so no license is needed on your computer). The communication between computer and hardware coud be on RS232 or RS485 interface or TCP/IP based on distance and your requests. If distance is small (1-3) meters) the cheaper solution is using RS 232 (or bRS 485). For bigger distances the TCP/IP communication involves usage of a supplementary web server circuit (20$ costs a ready to use one) and of course supplementary costs because of extended PCB. My proposal is:-hardware RS 232 communication (full design, BOM, 1-2 PCB manually manufactured and populated, boards already tested together with Labview program): 900$. -hardware with RS 485 communication: 900$ -hardware with TCP\IP communication: 1100$ -labview executable program for computer (which reads the voltages levels):400$ -regarding sending text/email I must analize the behaviour before bidding because I never use it before, but it is possible. So this is not included in my actual bid. Let me know if you are interested. Regards, Nicolae

Hi, Thank you for sharing this interesting project. We can achieve this by using the triplet circuit board. To explain simply, the base circuit can have set of threshold detectors and which can raise interrupt signals to the main circuit (built on tope of microprocessor). Thats can communicate to the PC either via Rs-232 port or wireless module if thats required (may be bluetooth/RF). In PC we can write a listener (incase of wireless we need to write additional driver). The software listener can be written using simple VisualBasic or a using python script, which can trigger the email notification. The cost involved in this process are the components (electronic circuit, ICs, processor, wireless sender & receiver, connectors), programming the circuit to monitor the signals/interrupts, software that listens on a PC, and finally the program that sends email. Hope I gave a short description of what I'm going to do. My brother works for Danieli Automation who will be assisting me with this project. Please let me know.

Hello sir, I can do this project for you. But I have a couple of suggestions. The datalogger that is to record the voltage levels can be used to send emails as well making the system completely independent of another computer or extra hardware. Also another method of delivery, you have mentioned is text; is it SMS or a pre-formatted text to be sent of any computer.

Yes, this product can be sourced. Do you want this to be a standalone piece of equipment, like a data logger? Or do you already have a host computer nearby? This can probably be done for less than $100 in hardware. Is this a one time installation, or are you looking to design a unit to be mass produced?

Hi, I've worked in similar projects. We can do this. 1) What do you mean with "sourced product"? 2) We can make a protoype, test it. Then design a optimized product and send it to manufacture. 3) Depending on the conmunication method y could estimate the cost per product in 200 U$S, maybe less.
