HiLetgo 2pcs MAX471 3A Current Sensor Module Consume Current Detection Module DC 0-3A
MAX471 3A Current Sensor Module
Current and voltage testing
Resistive voltage divider design
MAX471 chip on the board
Test Current range: DC0 - 3A
Description: 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 smaller For Arduino analog 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). for Arduino 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 0.00489Vx5=0.02445V The MAX471 chip on the board used to test the consume current of the load. Parameters: Test Voltage range: DC3 - 25V (for Arduino work on 5V) or DC3 - 16.5V (for Arduino work on 3.3V) Test Current range: DC0 - 3A Package included: 1* MAX471 3A Range Current Sensor Module Current Detection Module NEW
