To measure 1 A … WebThe Adafruit INA219 sensor is capable of measuring both DC voltage and current simultaneously. It also doesn’t have an analog output like aloof the other devices we have used so far, instead, this device has an I2C output. This makes it suitable for not only microcontrollers but also for microcomputers.
