INA219: High-Side DC Current & Voltage Sensor
The INA219 is a digital power monitor that allows you to measure both high-side voltage and DC current draw over an I2C interface. Unlike simple voltmeters, the INA219 calculates power consumption in real-time, making it an essential component for monitoring battery health and system efficiency.
- Bi-directional Sensing: Measures current in both directions—perfect for tracking both charging and discharging.
- High Precision: 12-bit ADC for accurate readings of voltage, current, and power.
- Wide Range: Capable of measuring up to 26V DC and up to 3.2A (with a standard 0.1 ohm shunt).
