ESP32 IoT Solar Power Monitoring & Battery Backup Kit
Build a practical renewable-energy dashboard with the ESP32 IoT Solar Power Monitoring & Battery Backup Kit, designed for engineering students, makers, robotics clubs and energy-management project teams in India. This project measures solar-panel voltage, current and calculated power using the popular INA219 high-side I2C current sensor module, then displays live readings on a compact 0.96-inch SSD1306 OLED screen. With ESP32 Wi-Fi capability, students can extend the build into a local HTTP dashboard or IoT logger for mini solar installations, battery experiments and smart-energy demonstrations. The kit uses a more realistic small solar power path: a 6V mini solar panel feeds a CN3065 solar Li-ion charger module for one 3.7V lithium cell, while an MT3608 boost converter can be adjusted to provide a regulated 5V rail for low-power experiments. An INA219 module is placed in the measurement path so learners can log voltage/current trends under different light and load conditions. A 1-channel relay and LED load set help demonstrate simple load switching, cut-off logic or energy-availability automation. This is a DIY educational kit, so users assemble the circuit, upload ESP32 code and calibrate readings as required. The 18650 Li-ion cell is not included; use a good-quality protected cell and observe polarity and charging safety. The selected modules are common in the Indian maker ecosystem and suitable for learning solar charging basics, DC-DC conversion, I2C sensing, OLED interfacing and ESP32 IoT monitoring in one complete power-and-energy project.
