DESCRIPTION

  • 2 Pieces.
  • 2pcs GY-471 3A Range Current Sensor Module MAX471 Module Board.
  • Size: 19.5 x 20.3mm.
  • This module can be used to test the current and voltage.
  • The principle of voltage test based on principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smallerAnalog input voltages up to 5 v, the voltage detection module input voltage not greater than 5Vx5 = 25V (if using 3.3V systems, input voltage not greater than 3.3Vx5 = 16.5V)AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V / 1023), so the minimum voltage of input voltage detection module is 0.00489 Vx5 = 0.02445V.
  • The MAX471 chip on the board used to test the consume current of the load.
  • Paramenter: Test Voltage range: DC 3V-25V (works at 5V e.gusing Arduino) or DC3 - 16.5V (works at 3.3V).
  • Test Current range: DC 0 - 3A.
