KSM048 Arduino Voltage Sensor 電壓感測模組

This module is based on principle of resistive voltage divider design， can make the Green terminal connector input voltage to 5 times smaller。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)。 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。

• Size: 30mm×10mm(approx)
• Voltage input range : DC0-25 V
• Voltage detection range : DC0.02445 V-25 V
• Voltage analog resolution : 0.00489 V
• Output Interface : “VCC ” connected 5/3.3V, “GND” connected GND, “OUT” connected Arduino AD pins
• DC input interface :Green terminal “+” with VCC, “-” with GND
• By 3P connector, connect this module with the expansion of board Arduino, not only makes it easier for you to detect voltage battery。
