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 within26V 8A, and the maximum relative error is no more than 0.2% (A simple manualcalibration is required before usage). It can be used for power consumption orbattery life evaluation of solar energy systems, battery, motors, controller orelectronic modules.Specifications:- Accessory Type: Gravity I2C Digital Wattmeter- Kit Contents: 0- For Use With: 0- 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- Input voltage range from 3.3V to 5.5V- 4mV voltage resolution- 1mA current resolution and 0.7mA quiescent current- Gravity I2C (logic level: 0-3.3V) interface- I2C address: four options 0x40, 0x41, 0x44, 0x45- Dimension is 30.0mm x 22.0mm/1.18 x 0.87in
