Product description 5A/20A/30A Range Current Sensor ACS712 Module AC/DC The ACS712 current sensor module provides precise solutions for AC/DC current sensing in industrial, commercial, and communications systems.
Note: there are 3 specifications of the product 5A/20A/30A, Pls choose them accroding to your needs.
Applications: ACS712 Module can be used in motor control, switched-mode power supplies, load detection and management, and overcurrent fault protection ect.
Note: ACS712 is based on the principle of Hall detection, please avoid the influence of magnetic field when using it! Voltage Sensor DC 0~25V
Voltage Detection Module Description: This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, for 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 3.3V x5 = 16.5V ). Because for 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 input voltage of 0.00489V × 5 = 0.02445V. 5A/20A/30A Range Current Sensor ACS712 Module AC/DC &Voltage Sensor DC 0~25V Voltage Detection Module 5A Range Current Sensor ACS712 Module AC/DC Features: Current
