Monitoring a board’s power consumption over the internet with @adafruitio #IoTuesdays

Groguard is using two Feather-compatible Giant boards to send power consumption data to Adafruit IO for real-time visualization (and possibly long-term logging). Instead of using a multimeter, he’s using a INA219 DC current sensor to monitor current draw over I2C.

From Twitter:

I’ve been trying to work on the low power modes as well as getting a general sense of what specific FeatherWings draw. I’m also going to be doing some battery testing soon as well.

Adafruit.IO is perfect for logging power consumption of any internet-connected device – from boards to connected projects.

8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
