This project involves designing a device that can monitor dual DC battery inputs, typically in the range of 30-60v DC. The device should also be powered by Power Over Ethernet (POE). Key Requirements: - The monitor must have web browser-based access for live data monitoring. Compatible with iOS and Mac. - It should be capable of dual voltage monitoring (with a voltage range of 30-60v DC) and potentially dual current monitoring for two DC battery inputs (with a maximum draw of 10 amps). - Experience with Arduino and network-based projects is a must. - The web browser-based access must also include functionality to change the IP address/subne...

    I'm in need of a circuit board designed to continuously monitor the voltage of a battery bank comprising 24 cells. This circuit board should have the following features: - Real-Time Display: The circuit should have a digital readout for real-time monitoring of the battery voltage. The readout should be clear and easy to interpret. The ideal freelancer for this job should have a solid background in electronics and circuit design, and experience with creating circuit boards for battery monitoring. They should also be able to create a digital readout that is user-friendly and reliable. It should be rotable for finding individual cells voltage as and when required
