Max471 Voltage Current Sensor Volt Amp Test Sensors Module For Arduino -Green And Blue

Product Description

This module can be used to test the current and voltage.The principle of voltage test based on the principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller.analog input voltages up to 5 v. AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V 5V per 1023, so the minimum voltage of the input voltage detection module is 0.00489Vx5 equal 0.02445V. The MAX471 chip on the board was used to test the consumed current of the load.
