Description
The INA219 board senses across shunts on buses that can vary from 0 to 26 V. This breakout is a current shunt and power monitor with an I2C- or SMBUS-compatible interface. The device monitors both shunt voltage drop and bus supply voltage, with programmable conversion times and filtering. A programmable calibration value, combined with an internal multiplier, enables direct readouts of current in amperes. An additional multiplying register calculates power in watts. The I2C or SMBUS-compatible interface features 16 programmable addresses.
You can use this breakout to measure both the high side voltage and DC current draw over I2C with 1% precision.

The INA219 is a highly accurate voltage, current, and power monitor sensor that operates over a wide range of voltages from 0 to 26V DC. It has an I2C communication interface that enables easy integration with microcontrollers and other digital systems. The sensor breakout can measure voltage with an accuracy of 0.4%, current with an accuracy of 1%, and power with an accuracy of 1%. It has a programmable gain amplifier that can be set to one of eight gain values, allowing for precise measurements even at low voltages or currents.
The INA219 also has an integrated shunt resistor that enables it to measure current with very low resistance and minimal power loss. It has a low quiescent current of 1mA, which means it can be left in a low-power standby mode when not in use. The sensor breakout also features an alert pin that can be programmed to trigger an interrupt when a preset threshold is exceeded, making it ideal for monitoring critical systems or equipment.
The I2C interface allows for easy configuration and data retrieval using a variety of programming languages and development platforms. The INA219 also includes a built-in calibration function that compensates for manufacturing variations and ensures accurate readings across a wide range of operating conditions.
The INA219 voltage, current, and power monitor sensor breakout with I2C communication interface provides an excellent solution for measuring and monitoring electrical parameters in a variety of applications. Its high accuracy, low power consumption, and programmable features make it a versatile and reliable choice for developers and engineers.

A Voltage, Current, Power Monitor Sensor Breakout is a type of electronic device that measures and monitors the voltage, current, and power consumption of an electrical circuit. The sensor breakout is typically connected to the circuit being monitored using wires or probes, and it can provide real-time data on the circuit's electrical characteristics. Voltage refers to the electrical potential difference between two points in the circuit, while current is the flow of electrical charge through the circuit. Power is the rate at which energy is transferred or used in the circuit. The sensor breakout provides information on these parameters, allowing for precise monitoring and control of electrical circuits. This can be particularly useful in applications such as renewable energy systems, battery management, and industrial automation.
