The Zio Current and Voltage Sensor is a highly accurate current and power monitor. Utilizing the INA219, it's able to read DC current and power over I2C with up to 1% precision. This is a great fit for a variety of applications, including estimating battery life, tracking solar power generation, or monitoring electricity consumption.
This sensor can measure voltage up to 26VDC and current up to 3.2A. The I2C interface makes it easy to daisy chain multiple devices and receive data via the Qwiic connect system.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
