Questions about the UV Sensor SKU:TOY0044

[quote]I have some questions about the UV Sensor SKU:TOY0044.
We are building a uv light sensing robot for an indoor setting with sunlight coming in through a window. Can this sensor provide an output large enough for arduino Mega to read? How much is the voltage output that it will be able to provide in an indoor setting? Would we need to amplify the output?[/quote]

Hi, the figure printed to the Serial should be the Analog Value. ;)

Phoebe 2013-08-01 07:29:01 Hi there,
I am using the following code for this sensor:
[code]
/*
# This Sample code is for testing the UV Sensor .
#Connection:
VCC-5V
GND-GND
OUT-Analog pin 0
*/
void setup()
{
Serial.begin(9600);// open serial port, set the baud rate to 9600 bps
}
void loop()
{
int sensorValue;
sensorValue = analogRead(0);//connect UV sensors to Analog 0
Serial.println(sensorValue);//print the value to serial
delay(200);
}
[/code]
The figure printed to the Serial will be the UV Index, the Vout or the Analog Value?
Thank you Portugal
