This module can be used to test the current and voltage.\u00a0<\/span>
\nThe 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.
