Description of INA219 Current Sensor Module INA219 Current Sensor Module The INA219 Current Sensor Module is a high-precision digital module used to measure DC current, voltage, and power in electronic circuits. It is based on the Texas Instruments INA219 IC and communicates with microcontrollers through the I2C interface, making it compatible with platforms such as Arduino, ESP8266, ESP32, and Raspberry Pi. This module uses a shunt-resistor–based current sensing method, which ensures accurate measurements with minimal power loss. It supports high-side (positive rail) current sensing, allowing current measurement without disturbing the ground path of the load. Due to its compact size, low power consumption, and reliable performance, the INA219 is widely used in battery monitoring, power management systems, solar energy projects, and embedded electronics applications.
