Introduction
Analog Voltage Divider (SKU: DFR0051) The Voltage Divider can detect the supply voltage up to
25V. The DFRobot Voltage Divider module is based on resistor divider principle. The voltage
detection module allows the input voltage to reduce 5 times. As the Arduino analog input voltage is
up to 5V, so voltage detection module's input voltage can not be greater than the 5Vx5 = 25V.
Specification
Interface: Analog
Input voltage (DC): Maximum 25V, Minimum 0.0245V
Detects the supply voltage upto 25V
Size:22x30mm

Sample Code
void setup()
{
Serial.begin(9600);
}
void loop()
{
int val;
float temp;
val=analogRead(0);//This divider module will divide the measured voltag
e by 5, the maximum voltage it can measure is 25V.
temp=val/40.92; //
val=(int)temp;//
Serial.println(val);
delay(100);
}
