This project monitors the voltage, current and remaining capacity of the battery of a camper. Voltage is measured using a voltage divider, current with a 30A hall sensor.
- Sparkfun Arduino Pro Micro: (~3$ clones on ebay), or any other Arduino.
- OLED I²C 0.96" SSD1306 based display (e.g. Crius CO-16)
- Voltage divider (e.g. 10k and 5.6k Ohms) for measuring the voltage
- Hall sensor: ACS712 30A (breakout board from ebay ~5$) for measuring the current
- Adafruit ADS1115 16-bit ADC breakout board
- Better view handling
