Gravity: I2C digital wattmeter
Description I2C Digital Wattmeter - DFRobot Gravity
This is the I2C digital wattmeter of DFRobot Gravity sensor series. It features high resolution and precision, and can measure voltage, current and power up to 26V 8A. Simple manual calibration is required before use. After that, the maximum relative error is up to ±0.2%.
The module uses a TI INA219 zero temperature drift current/power monitoring chip. It also contains a 2W high power low temperature drift 10mΩ alloy sampling resistor. The voltage and current resolution can reach 4mV and 1mA respectively. Under the full scale measurement condition, the maximum relative error of the measurement can be greater than 0.2% . It also provides four I2C addresses which can be configured via the 2P DIP switch. The module accurately measures bidirectional high-side currents. It is ideal in applications such as solar or battery meters where the battery needs to be charged and discharged . This status can be easily determined by positive or negative current measurements. In motor applications, the current can be monitored in real time.
