USB-Based Smart Battery Analyzer for Eco-Friendly Monitoring

Created using ChatSlide

This presentation introduces a USB-based battery analysis system integrated with an Android app, designed to measure voltage, current, power, and capacity. It addresses the growing reliance on lithium-ion batteries by providing an efficient monitoring solution that incorporates an ESP-32 microcontroller, an ADS1115 ADC, and an ILI9225 LCD for operational insights. By situating the analyzer between the charger and load, it transmits data via Bluetooth, achieving a voltage error of only 0.4%....
