Adafruit 4226 INA260 High or Low Side Voltage, Current, Power Sensor

Easy to use. Accurate when compared with a Fluke 87 meter. Like the option to use on the high side.

Standard DC voltage/current monitor. It is easily integrated into an Arduino based system, or any single board computer. Four interconnects are required, Vcc, Gnd, SCL and SCA. I use the device interfaced to a generic ESP32 board, in a Home Assistant monitoring system.

I've been using the Adafruit INA260 ... Sensor for a few months now, and I'm overall very impressed with it. It's an accurate, precise, and easy-to-use current sensor that's perfect for most applications. However, there are a few flaws that I've noticed. First, the sensor can only measure DC current. If you need to measure AC current, you'll need to look for a different sensor. Second, the sensor is not very fast. It can only update its measurements once per second. If you need to measure current at a faster rate, you'll need to look for a different sensor. Third, the shunt resistor is integrated, so you can't change it. This means that the sensor is only good for measuring currents up to 15 amps. If you need to measure higher currents, you'll need to look for a different sensor with a higher shunt resistor. Despite these flaws, the Adafruit INA260 is still a great current sensor for most applications. If you're looking for an accurate, precise, and easy-to-use current sensor that can measure DC current up to 15 amps, then the INA260 is a great option. Pros: Incredibly accurate and precise Can measure high or low side current, bus voltage, and power Easy to interface with any microcontroller Wide voltage and current ranges Affordable Cons: Can only measure DC current Not very fast Integrated shunt resistor limits current measurement to 15 amps Sensor can be sensitive to noise Sensor can be difficult to solder Datasheet is not very clear

This is the only unit that I can find that will do 30v and 10A. Works flawlessly, and pretty accurate as well!

You MUST solder and be familiar with R Pi or Arduino, but these guys are SUPER nice to use. I set up 5 on a prototype board and now I monitor all the various parts of my development robot so I finally understand what consumes battery life. Took a few hours to figure out and assemble, but the code is easy (Thanks Adafruit!) and once its done, it's very helpful. I'm buying more to attach to other devices and connecting the whole lab with MQTT messaging service so I can monitor everything from one computer. NOTE: Must have a ground common to the INA260. Also, if you overcurrent, they instantly self-destruct.

work great with no problem at all

I love these products and have purchased a few from adafruit over the past couple of years. Typically sold on amazon for about double that but then I have prime and the shipping is 'free'. Adafruit website has a good tutorial for the use. They are very accurate.

1 out of two of my boards is still working. Aparently, it cant handle over 1 amp, atleast thats the power that was going through it when it went up in smoke...literally. I finally figured out all of the coding just to see it melt before my eyes. Watch out for this one.

Once again, Adafruit delivers with the INA260 High or Low Side Voltage, Current, and Power Sensor. This sensor is a true gem for anyone involved in detailed power monitoring projects. Its ability to measure voltage, current, and power with high precision makes it an invaluable tool for both hobbyist and professional applications. What sets the INA260 apart is its versatility. It can be used for both high and low side measurements, which provides great flexibility depending on the project needs. Whether it's for battery monitoring, power supply testing, or energy consumption analysis, this sensor performs exceptionally well. The accuracy of the readings is impressive. With the INA260, I've been able to get precise and reliable data, which is crucial for any project where power measurement is key. The I2C interface makes it easy to integrate with a microcontroller, and Adafruit's comprehensive documentation and libraries make setup and programming a breeze. The build quality, as with most Adafruit products, is top-notch. This sensor is robust and well-designed, ensuring it can handle continuous use in various environments. In summary, the Adafruit 4226 INA260 is yet another example of Adafruit's commitment to quality and functionality. It's an excellent choice for anyone needing a reliable and precise power sensor for their electronics projects.

The unit i received was defective: not discoverable on I2C bus scan, and if when attempting to read voltage and current, the central chip got incredibly hot. Purchased a 5 pack of INA219 sensors, perfect readings immediately. Returned for refund.
