I built a simple Power Meter you can use to measure 0-26V and up to 3.2A. Which makes a great addition to your workshop by allowing you to monitor voltage, current, power and energy used over time on almost any DC device.
I used a INA219 (High Side DC Voltage and Current I2C Module). These are very cheap. I got a 5 pack on special for $7.
Right now it just polls at 1second… I tried to set up a slider for the interval but ran in to problems so will sleep on it. I did however just set up a HOLD button so you can pause the polling.
There are many more features I would love to add. But currently this is working perfectly. So it would be a geat place for people to start with a working example for Blynk. So I would love to see what other ideas people can come up with. Please leave comments below.
