Gravity INA219 I2C Digital Wattmeter Bi-Directional Current Sensor Voltage Measurement Power Supply Sensor Breakout Module

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 Specifications Input Voltage (VCC) : 3.3V~5.5V Voltage Range (IN+ or IN- relative to GND): 0 ~ 26 V Voltage Resolution: 4 mV Voltage Relative Error: < ± 0.2% (Typical) Current Range: 0 ~ ±8A (Bidirectional current) Current Resolution: 1mA Current Relative Error: < ± 0.2% (Typical, manual calibration required) Power Range: 0 ~ 206 W Power Resolution: 20 mW (Hardware) / 4 mW (Software) Quiescent Current: 0.7 mA Interface: Gravity I2C (logic level: 0-3.3V) I2C Address: Four options 0x40, 0x41, 0x44, 0x45 Dimension: 30.0mm*22.0mm/1.18*0.87 in Weight: 4g Shipping list 1 x Gravity: I2C Digital Wattmeter 1 x XH2.54-4P Black Header 1 x Gravity-4P I2C/UART Sensor Wire
