Testing measurement

A project log for Power logger with Raspberry Pi

The idea is to take Raspberry Pi, current/voltage meter INA219, and visualize the data by the web interface.

Built a simple circuit for testing. 4.7K resistor with known voltage

3.26V / 4700 Ohm = 7e-4 A = 0.7 mA

That what I see at the graph. So I can trust to measurements. Still some deviations here. Around 0.1 mA.
