Current & Power I2C sensor (INA219)

The PowerSense INA219 is a high-precision current and power monitoring module that communicates over I2C. Designed for projects that require accurate power measurement, it allows you to monitor voltage, current, and power consumption of a connected load. It's ideal for battery-powered systems, solar projects, and embedded electronics where efficient energy usage is critical.
