Скачать или смотреть DIY NMEA2000 compatible Battery Monitor using SensESP/ESP32 - Part 2 - Tech E13 - Après Sail

In this episode we prepare the circuit boards needed for the DIY NMEA 2000 and Signal K compatible Battery Monitor and bring it all together with the ESP32 Firebeetle 2. We also review the software we have setup to output NMEA2000 messages.

The data that the Nautical Sun NMEA battery Monitor will provide is as follows:
• For Each Battery
○ Voltage
○ Current Draw (+) or charge (-)
○ Battery Temperature
○ State of charge
○ Manually inputted data for NMEA2000 battery identification (Battery Chemistry, Battery capacity, etc)
• Outside Temperature

The device will output the following sentences, for each battery (if Implemented):
• PGN 127506 - DC Detailed Status
• PGN 127508 - Battery Status
• PGN 127513 - Battery Configuration Status
• PGN 130312 - Outside Temperature

SV Après is a 1996 Hunter 336 Captained and Maintained by Jason and usually sailing out of Milwaukee's South Shore Yacht Club in Lake Michigan, one of the US's Great Lakes. The filming is done via GoPro's, DJI Mavic drone and iPhone and spliced together a bit hap hazardly.
