INA226 CJMCU-226 Bidirectional Current Power Monitoring Sensor Module 5pcs I2C Interface Compatible with Arduino Raspberry Pi

The module communicates via an I2C-compatible interface, allowing up to 16 programmable addresses on a single bus. This flexibility simplifies system design by reducing wiring complexity when monitoring multiple power lines. It integrates smoothly with standard microcontrollers like Arduino and Raspberry Pi for streamlined data acquisition.

Capable of both high-side and low-side power measurement, the sensor tracks current flow in either direction. This bidirectional functionality is essential for systems where power may be supplied or drawn, such as battery management or motor control. It handles common bus voltages up to 36 V with ease.

The package contains five current monitoring sensor modules and five corresponding pins, providing enough units for multi-channel setups or backup components. Note that factory print batch numbers may vary between units. The contents are strictly limited to these items, ensuring you know exactly what arrives at your workbench.

• Monitors bus voltages from 0 V to 36 V with high accuracy
• Features I2C interface supporting up to 16 programmable addresses
• Includes five sensor modules and five pins in the package
• Operates within a temperature range of -40°C to 125°C
• Blue PCB design with low-side and high-side measurement capability

The INA226 is a current-voltage sensing and power measurement device with an I2C or SMBUS compatible interface. The device monitors both the voltage drop across the shunt and the bus voltage. Programmable calibration value, conversion times, and averaging, combined with an internal multiplier, allow for direct readings of current in amps and power in watts. The INA226 senses current on common bus voltages that can range from 0 V to 36 V, of the supply voltage. The device operates from a single 2.7 V to 5.5 V supply and typically draws 330 A of supply current. The device is specified over the operating temperature range of -40°C to 125°C and has up to 16 programmable addresses on the I2C-compatible interface. CJMCU – 226 – supports alarm function for 36 V, bidirectional, high-precision, low-side and high-side power measurement, I2C output current. The highest INA226 interference voltage of 10 microvolts (uV), the largest gain error is 0.1%, the accuracy is 10 times higher than industry-leading competitive products. This device is a complete 16-bit single-circuit solution, to number the I2C interface for current, voltage and power to provide comprehensive programmable measurement. INA226 for servers, computers, telecommunications equipment, power line equipment and test equipment design personnel with great advantages, can fully meet the requirements of accurate power measurement.
