Gravity: I2C Digital Watmeter


Gravity: I2C Digital WatmeterIt is a high-resolution, high-precision, large-scale measuring module that can measure the voltage, current and power of various electronic modules and electrical equipment within 26V 8A, with a maximum relative error of ± 0.2% maximum (A simple manual calibration is required before use). It can be used in the power consumption or battery life assessment of solar energy systems, battery, motors, controller or electronic modules.

The module adopts TI INA219 zero temperature bias current / power monitoring chip and 2W high power low temperature deviation 10mΩ alloy sampling resistor. Voltage and current resolution can reach 4mV and 1mA respectively. Under full scale measurement condition, the maximum relative error of voltage and current measurement can be greater than ± 0.2%. It also provides four I2C addresses that can be configured with a 2P DIP switch.

Module,Accurately measures bidirectional high side currents (battery positive passing through the power source), which is particularly useful in solar or battery fuel gauge applications where the battery needs to be charged and discharged. This situation can be easily determined by simple or positive current readings. In motor applications, the current can be monitored in real time by monitoring whether the motor current is too large due to overcurrent. In addition, you can use this module to measure the entire project to evaluate the power consumption of various electronic modules or battery life.

Solar Energy Management, Battery Fuel Indicator, Electronic Module Power Evaluation are the application areas.
