Crowtail- Voltage Sensor

Description

The Crowtai- Voltage Sensor module designed on the basis of the input voltage is not greater than 5 V x 5 = 25 V (if use 3.3 V system, the input voltage is not greater than 3.3 Vx5 = 16.5 V).Because the Aduino using AVR chip for 10 AD, so this module simulation resolution of 0.00489 V (5 V / 1023), so the voltage detecting module minimum input voltage of 0.00489 V * 5 = 0.02445 V.

Usage

Here is an example showing how to turn on the Crowtail- Voltage Sensor.

1. Plug it onto the Analog port 2 of Crowtail - Base Shield using a Crowtail cable.

2.Plug the Crowtail - Base Shield onto Arduino.

3. Connect Arduino to PC by using a USB cable.

4.parallel the Metering ports to the object that you want to measure.

5. Copy and paste code below to a new Arduino sketch, and upload it to your Arduino.

#include <Wire.h>
float val11; 
void setup() 
{    
 Serial.begin(9600);   
 Serial.println("Emartee.Com");   
 Serial.println("Voltage: ");   
 Serial.print("V  "); 
} 
void loop() 
{       
 float temp;       
 val11=analogRead(2);       
 temp=val11/40.92;              
 Serial.println(temp);          
 delay(1000); 
}

5.When you upload the code complete,you can measure the voltage(0-25V) of different objects and see the result via the serial port debug window
