As one of my first DIY projects, I'm going to build a battery monitor for the DC battery/solar/inverter system in my camper van. The van has 440 Ah of lead acid batteries and DC currents up to 200A to the inverter, although more typical currents are in the 0-5A range. A variety of battery chemistries may be managed with these AFEs, including Lithium Ion, Lithium iron phosphate, and more. In the attached code you will find a working example of filtering and displaying msg ID 6F2 (Battery Cells Voltage and Temperature). Aux Battery monitor advantages. This is why we’re passionate about sourcing the perfect Electronics Kits for anyone whose eager to learn – to prove that there is an exciting way to learn electronics, with a curriculum of projects that you actually want to do. My idea was to measure the battery level with Arduino by connecting its positive to an analog input and read the voltage level. The coding of the Arduino was extremely simple apart from a bug in the LCD code I downloaded and an initially poor choice in the SD code that I used which was remedied with the newer code on the Sparkfun site. The DHT11 sensor senses humidity and temperature, and sends the information to digital pin 5 of Arduino MCU, as shown in Fig.
