Unknown Temperature Sensor

Hello,

I have an unknown temeprature sensor that has 3 wires.

I got it from my rc helicopter charger and thoght of using it with netduino plus.

I have connected it to 3.3V, GND & A0.

When i read the value I get a 3 digit number between 790 to 810.

Any idea how to translate this to real temperature ?

Are there any numbers on the sensor package?   What is your room temperature, resp. temperature where the sensor is located? (Nearby heat sources like LCD monitor, power supply etc. can affect local temperature).

There are no numbers on the sensor.

My room temp is around 20C at the moment.and the sensor is located on my table.

Could you please show the code from which you get those 790, 810 results? Does it already include scale conversion ("x*3.3/1023")?

int read = temp.Read();byte bA = (byte)(read/100);byte bB = (byte)(int.Parse(read.ToString().Substring(1)) / 10);byte bC = (byte)int.Parse(read.ToString().Substring(2));int milivolts = read * (3300 / 1024);int tempC = (milivolts - 500) / 10;Debug.Print("Read " + read + ", Milivolts " + milivolts + ", TempC " + tempC + ", byte " + bA +" " +bB + " " +bC);

So, you've already figured it out (?)
