New Voltage Sensor Detection Module Electronic Building Blocks For Robot Arduino
100% Brand New And High Quality
This module is based on the principle of the resistor divider design, enabling the terminal interface input voltage reduced five times, Arduino analog input voltage up to 5V, then the voltage detection module can not be greater than the input voltage of 5V × 5 = 25V (3.3V if used system, the input voltage can not exceed 3.3Vx5 = 16.5V). Because Arduino AVR chips used in 10 AD, so this module's analog resolution 0.00489V (5V/1023), so the input voltage detection module detects a minimum voltage of 0.00489V × 5 = 0.02445V.
Parameters:
Voltage input range: DC0-25V
Voltage Detection range: DC0.02445V-25V
Voltage Analog Resolution: 0.00489V
DC input connector: Terminal cathode connected VCC, anode to GND
Output Interface: "+" connect 5/3.3V, "-" connect GND, "s" the Arduino AD pins
Reference Code:
#include <Wire.h>
int val11;
int val2;
void setup()
{
pinMode(LED1,OUTPUT);
Serial.begin(9600);
Serial.println("Emartee.Com");
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);
}
Package includes:
1 x Arduino voltage detection module
