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. 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). 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.
Paramenter:
Test Voltage range: DC3 – 25V (Arduino work on 5V) or DC3 – 16.5V (Arduino work on 3.3V)
Test Current range: DC 0 – 3A
