This module is based on principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller.
DC 0-25V voltage sensor module input voltages up to 5v,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)
Voltage tester sensor the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.
This voltage detection sensor module DC 0-25V can work with analog single phase
Resolution: 0.00489V; input : Terminal cathode connected to VCC, GND negative pole; Output interface: "+" then 5/3.3V, "-" then GND, "s" then the for AD pins.
