Product Description
Description:
- This module is based on resistive voltage divider design principles, It is capable of reducing the voltage of the input terminal connection five times.
- You can use a 5V maximum voltage on the ADC side of the module so which allows for a maximum of 25V on the input side.
- If 3.3V is used, the input voltage must not exceed 16.5V.
- Because AVR chips use 10 bit ADC, the maximum resolution of this module is 0.00489V (5V / 1023), so the voltage detection module detects minimum input voltage is 0.00489V × 5 = 0.02445V.
Parameters:
- Input voltage range: DC0-25V
- Voltage detection range: DC0.02445V - 25V
- Voltage analog resolutions: 0.00489V
- DC Input: positive terminal connected to VCC, GND negative pole
- Output interface: "+" then 5 / 3.3V, "-" then GND, "s" then the AD pin
- Size: Approx 27*14*12mm/ 1.06 x 0.55 x 0.47inch
Reference Code:
#include
int val11;
int val2;
void setup ()
{
pinMode (LED1, OUTPUT);
Serial.begin (9600);
Serial.println ("Logicware.com.au");
Serial.println ("Voltage:");
Serial.print ("V");
}
void loop ()
{
float temp;
val11 = analogRead (1);
temp = val11 / 4.092;
val11 = (int) temp; //
val2 = ((val11% 100) / 10);
Serial.println (val2);
delay (1000);
}
