Description
Current Sensor Module:
ACS712 Module can be used in motor control, switched-mode power supplies, load detection and management,and overcurrent fault protection ect.

Voltage Sensor Module:
This module is based on a resistive divider principle design, make the interface terminal 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 (if used 3.3V system, the input voltage can not exceed 3.3Vx5 = 16.5V). Because Arduino AVR chips used in 10 AD, so the resolution of the analog module is 0.00489V (5V / 1023), so the voltage detection module detects a minimum
