DFRobot Gravity: I2C Digital Wattmeter

Introduction
Gravity: I2C Digital Wattmeter is a high-resolution, high-precision, large-scale measurement module that can measure the voltage, current and power of various electronic modules and electrical equipment within 26V 8A, and the maximum relative error is less than ±0.2% (A simple manual calibration is required before usage). It can be used for power consumption or battery life evaluation of solar energy systems, battery, motors, controller or electronic modules.

Features
High precision, high resolution, large range, low temperature drift
Bidirectional current high side measurement
Compatible with 3.3V/5V controller
Sophisticated and compact, easy to embed in the project

Applications
Solar Power Management
Battery Fuel Gauge
Electronic Module Power Evaluation
