ITEMS DESCRIPTION

Description:
Module Features:
Measuring circuit voltage and current size.
Current detection by the United States Maxim’s production of precision high-side current sense amplifier chip MAX471. The module requires no external power supply, internal module power supply to be detected directly. MAX471 minimum operating current of 3V, this module detects the minimum voltage input is 3V.
Voltage detection resistor divider using the principles designed to make the terminal interface input voltage reduced 5 times. Arduino analog input voltage up to 5V, then the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V (3.3V if the system is used, the input voltage does not exceed 3.3Vx5 = 16.5V)

Detection Pin Description:
VT: voltage detection pin detection voltage is input voltage 1/5
AT: current sense pin
GND: pick Arduino GND
VOUT / VIN: VOUT = VIN

Parameter:
Voltage detection range: 3-25V (Arduino operating voltage of 5V) or 3-16.5V (Arduino operating voltage of 3.3v); current detection range: 0-3A, 2% accuracy, current-voltage conversion ratio of 1V / A

Example:
Use Arduino measuring load load size input voltage and current, where arduino working voltage is 5V.
