Please read the project description and do not bid if you don't have the appropriate skills. Thankyou I need somebody that can work with common microcontrollers eg atmel, arduino or NXP ect. The project will consist of a current sensing bi-directional hall effect sensor ACS758ECB-200B, a voltage divider circuit to measure input voltage, a standard 4 x 20 lcd and a suitable microcontroller to tie it all together. Depending on the microcontroller used an external ADC may be needed to maintain accuracy. 10 bit should be enough. I will need the bidder to provide me with a simple schematic so that i can do the PCB design. The bidder will also need to program the device to show the following. Positive and negative current as the sensor is bi-directional Input voltage Power in watts/ KW Watt hours / KW hours Amp hours / K amp hours Volts Peak Amps Peak I will design screen shots when the project is awarded to show how information is displayed on the screen and to what decimal places. I would also like to have an external interrupt trigger the device to save its currently displayed data once the microcontrollers supply drops below a predetermined amount. The device will then use this information upon startup. The project and code will also need to be confidential and not released afterwards. I will need an NDA signed. Thankyou for your bids.

hi, i am actually finishing up on a networked power monitoring system using arduino. we should use an ac-ac adaptor to get the voltage so we dont expose the microcontroller to the mains. and use a microcontroller supervisor to trigger an interrupt when the supply drops below a threshold. 4x20 lcd should not be a problem. i can actually give you the schematic and code in a week. but we still need the other week to do the debug. i am willing to sign a non-disclosure agreement. please let me know if i can help. best regards, ceazar
