Monitor 3 x phase to N voltage (+-230V) possibly also monitor N to Earth. (please specify accuracy) Monitor 3 (one for each phase) + 8 other current (max 150A) average around 6A with non-invasive, split core type sensor. (please specify accuracy). Measure these values at max sample rate (please specify). Built in protection to make unit durable, specially on voltage inputs. Log the values plus date&time whenever a value changes to local storage. Adjustable threshold. Between about 0.01v and 1v (subject to the accuracy) Upload the data via GPRS to server as text file or direct to mysql database. Was thinking of using Arduino Mega, if you would prefer alternative please specify and justify. Try to keep hardware cost down by using low cost but decent quality parts that are available to every country eg aliexpress. All source code , rights and suppliers of hardware with part numbers and url’s must be supplied. Price for development cost plus 3 units. One for developer to keep for troubleshooting if necessary and 2 x for client. Cost for additional units. Cost excluding postage/courier. If there is anything you do not agree with please let me know

THIS IS INCLUDING ALL COSTS. Hello, I am Anthony from Sri lanka. I have 7 years of experience in the filed and I am very much interested in your project. Why you should hire me ? * As a full time freelancer I have my own PCB fabrication work shop and testing lab. So there is no problem doing live tests with you after the device has been developed. * My workshop is equipped with CNC machine, FDM 3D printer and DLP 3D printer. So there is no problem designing and printing plastic parts you required. Please contact me if you are interested. Thank you Anthony

Before awarding to anyone, give me a chance to discuss it with you. I am embedded system electronics engineer with 3 years of experience development of remote monitoring/control systems. I have worked on home automation, beacon based indoor positioning system, smart parking system with data logger of parking spots availability, etc. Another iot product I worked on was women saftety device, on which, if women press the button, her location is shared with her family members and it starts recording audio to a cloud server automatically, while at the same time it calls nearest police station automatically. Please consider sending me a message so that we can discuss this further
