CJMCU-219 INA219 I2C Bi-directional Current Power Monitor Sensor Module

CJMCU-219 INA219 I2C Bi-directional Current & Power Monitor Sensor Module

The CJMCU-219 INA219 Current Sensor Module is a high-precision, bi-directional current and power monitoring solution designed for advanced electronics, embedded systems, and IoT applications. Based on the highly reliable INA219 chip, this module allows accurate measurement of current, voltage, and power via the I2C communication interface, making it an essential tool for engineers, students, and DIY enthusiasts.

Unlike traditional current sensing methods, the INA219 uses a precision shunt resistor and internal ADC, enabling it to measure both high-side current (between power source and load) and bi-directional current flow. This makes it ideal for battery monitoring, solar systems, and power management applications where current direction matters.
