DFRobot (SEN0291) I2C Digital Wattmeter, I2C/UART 4-Pin Sensor Wire

SEN0291 is a Gravity: I2C digital wattmeter module. This 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 no more 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.
