Description

Description:

This DC voltage sensor can detect voltage from 0 to 25V. Sensor is based on resistance points pressure principle, and it can make the input voltage of red terminal reduce 5 times of original voltage.
 
The max Arduino analog input voltage is 5 V, so the input voltage of this module should be not more than 5 V x 5 = 25 V ( if for 3.3 V system, the input voltage should be not more than 3.3 V x 5 = 16.5 V ). 
 
Because the Arduino AVR chip have 10 bit AD, so this module simulation resolution is 0.00489 V (5 V / 1023), and the input voltage of this module should be more than 0.00489 V x 5 = 0.02445 V.
 

Sketch:

int analogInput = A1;
float vout = 0.0;
float vin = 0.0;
int value = 0;
float R1 = 30000.0; 
float R2 = 7500.0;
 
void setup(){
   pinMode(analogInput, INPUT);
   Serial.begin(9600);
   Serial.print(“DC VOLTMETER”);
}
 
void loop(){
   // read the value at analog input
   value = analogRead(analogInput);
   vout = (value * 5.0) / 1023.0; // see text
   vin = vout / (R2/(R1+R2)); 
   
Serial.print(“INPUT V= “);
Serial.println(vin,2);
delay(500);
}
