2 Pcs New Standard Voltage Sensor Module Components Kit For For Arduino
Features:
This module is based on the principle of resistive voltage divider design;
can make the red terminal connector input voltage to 5 times.
Arduino analog input voltages up to 5 v,the voltage detection module input voltage not exceeds 5Vx5=25V.
(if using 3.3V systems, input voltage not exceeds 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.
DC input interface : red terminal positive with VCC, negative 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,
but also use the IICLCD1602 LCD to display voltage.
Specification:
Condition:100% brand new
Size: 25mm×13mm/0.98"×0.51"(approx)
Voltage input range : DC0-25 V
Voltage detection range : DC0.02445 V-25 V
Voltage analog resolution : 0.00489 V
Output Interface : "+ " connected 5/3.3V, "-" connected GND, "s" connected Arduino AD pins
Reference Code：
#include
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);}
