Voltage and current monitor sensor, 3 channels, INA3221, I2C, SMBUS, 2.7-5.5V

Voltage and current monitor sensor INA3221, compatible with Arduino and other development boards on both 3V and 5V, is an advanced three-channel module, designed for precise monitoring of supply voltages and current consumed by components or devices in a electronic system. It measures both the voltage drops at the shunts and the supply voltages of the system and provides precise data regarding them.

With an operating voltage between 2.7V and 5.5V, the sensor can be conveniently powered from variable voltage sources. The device maintains a high energy efficiency, consuming only 350 µA of current in operation.

The INA3221 has precision features, with minimal offsets and reduced gain errors, which ensure reliable measurements. In addition, it offers configurable options for averaging the measured data, allowing the user to adapt the performance of the sensor to the specific requirements of the application.

With four programmable I2C addresses and alert and warning functions, the INA3221 allows the detection and management of errors or out-of-range conditions, facilitating efficient system monitoring and control.
