Zio Current and Voltage Sensor - INA219 (Qwiic)

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.这是一个很好的适合各种各样的应用程序,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 金沙线上娱乐场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.

Zio Current and Voltage Sensor - INA219 (Qwiic) Product Help and Resources

Core Skill:Programming

If a board needs code or communicates somehow,you're going to need to know how to program or interface with it.The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie- You will need a better fundamental understand of what code is,and how it works.You will be using beginner-level software and development tools like Arduino.You will be dealing directly with code,but numerous examples and libraries are available.Sensors or shields will communicate with serial or TTL.

Core Skill:Electrical Prototyping

If it requires power,you need to know how much,what all the pins do,and how to hook it up.You may need to reference datasheets,schematics,and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie- You may be required to know a bit more about the component,such as orientation,or how to hook it up,in addition to power requirements.You will need to understand polarized components.
