INA226 Модуль датчика контроля напряжения тока CJMCU-226 IIC I2C

Features:

The INA226 is a current shunt and power monitor with an I2C or SMBUS compatible interface.

The device simultaneously monitors the shunt voltage drop and the bus supply voltage.

Programmable calibration values, conversion times and averaging combined with an internal multiplier allow direct reading of current in amperes and power in watts.

The INA226 senses the current on the common-mode bus voltage, which can vary from 0 V to 36 V, independent of the supply voltage. The device operates from a single 2.7V to 5.5V supply and typically consumes 330 µA.

The device is rated for operation from –40°C to 125xC2°C and has up to 16 programmable addresses on an I 2 C compatible interface.
