Wattmeter I2C Digital Gravity for Arduino


Within 26V 8A, this wattmeter can measure voltage, current and power of various electronic modules. It is a high-resolution, high-precision and large scale measuring module. The relative error is no more than ±0.2%. The ideal uses are for battery consumption. 

The module adopts TI INA219 zero temperature drift current/power monitoring chip and 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 voltage and current measurement can be superior to ±0.2%. It also provides four I2C addresses that can be configured via the 2P DIP switch. The module accurately measures bi-directional high-side currents (current flowing through the power supply or battery positive), which is especially useful in solar or battery fuel gauge applications where the battery needs to be charged and discharged. This status can be simply determined by positive or negative current readings. In the motor applications, the current can be monitored in real time by monitoring whether the motor current is too large due to overload.
