Open-Source DC Energy Meter Featuring Blynk Cloud Monitoring
Awesome project and write-up from maker Adrian Cubas that incorporates both our SSD1306 OLED Display and INA219 .
If you’ve ever worked on a tech project involving voltage and current measurements, you’ve likely felt the need to record those values for future analysis and decision-making. Personally, I’ve faced this challenge many times, especially when trying to determine the performance of Windturer Wind Turbine. Dealing with interconnecting cables to multimeters, ensuring the wind turbine doesn’t interfere with the cables, and making sure the camera correctly captures the values can be tedious and error-prone due to the number of variables to manage simultaneously.
In this project, I present the solution I developed to overcome this problem. Unable to find any commercial solution, I decided to create my own. I designed a device that measures current and voltage at short intervals and calculates other variables such as consumed energy and power.
