DFRobot Gravity INA219 I2C Digital Wattmeter

The Gravity INA219 I2C Digital Wattmeter from DFRobot is a high-precision measurement module specifically designed for capturing voltage, current, and power in electrical devices and modules. With a measurement range of up to 26V and 8A, this module offers high accuracy with a maximum relative error of only ±0.2%. Simple manual calibration is required before use. The module is ideal for applications such as evaluating power consumption or battery life in solar systems, motors, and other electronic modules. It allows for the simultaneous use of up to four modules across different I2C addresses, increasing flexibility in application. The bidirectional current measurement is particularly advantageous for monitoring batteries, as both charging and discharging processes can be accurately captured. Additionally, the module is compatible with 3.3V and 5V controllers and can be easily integrated into various projects.
