The INA219 DC Current Sensor Module is a high-side current and power monitoring sensor based on the INA219 precision current monitor IC. It measures shunt voltage, bus voltage, current, and power consumption through an I²C interface, making it ideal for battery monitoring, solar energy systems, power management, and embedded electronics projects.
The module can accurately monitor both current draw and supply voltage, allowing real-time power analysis in Arduino, ESP32, Raspberry Pi, STM32, and other microcontroller-based systems.
