Product Descriptions

Item 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. 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

Features:

   
• Test Voltage range: DC3 - 25V (for Arduino work on 5V) or DC3 – 16.5V (for Arduino work on 3.3V)
        Test Current range: DC 0 - 3A
        Example: (Working Voltage:5V)
