Product Description
The INA219 DC Current Measurement Module is a digital power-monitoring solution for measuring electrical parameters in DC circuits. It can monitor bus voltage and current, with power consumption derived from these measurements, making it useful for analyzing the performance of electronic loads and power supplies.
The module uses the I2C interface, allowing measurement data to be read by a microcontroller or single-board computer with minimal wiring. This makes it convenient for projects where real-time electrical monitoring is required.
One of the key advantages of the INA219 is its high-side current measurement capability. This allows current to be monitored on the positive supply path while maintaining a common ground between the power source, load, and controller.
