INA219

Current and voltage measurement with a digital interface.

Tutorial / documentation

Sensors

First tests with INA219

  1. Identify the exact INA219 variant, package and manufacturer documentation.
  2. Identify power, ground and signal pins in the documentation. Assemble the circuit with power disconnected.
  3. Follow the manufacturer’s evaluation circuit. Use a current-limited low-voltage supply and the recommended logic levels.
  4. Mesurez les signaux d’entrée et de sortie. Comparez leur comportement à la fonction : mesure de courant et de tension par interface numérique.
