Gravity: INA219 Current and Power Monitor
Overview
The SEN0291 is a high-precision digital power monitoring module based on the INA219 IC, designed for measuring voltage, current, and power over an I2C interface. It features a Gravity-compatible connector for easy integration with 3.3V and 5V microcontrollers and can measure high-side currents up to 8A.
Why Choose This Part
This module provides high-accuracy measurements with a 0.2% error rate and 12-bit resolution across a wide 0-26V voltage range. Its bidirectional sensing capability allows for monitoring both charging and discharging states in battery-powered applications.
Applications
Key Specifications
Getting Started
