How to get temperature value from DS18B20 voltage

Question

I just connected DS18B20 temperature sensor to ADC of a device. But that device only shows voltage reading from ADC likve 1033 mV. But I want to get an actual temperature value from the voltage value. Is there any way to calculate or get the temperature value from voltage reading?

Please let me know.

Thanks,

You need to connect the 18B20 to a microcontroller, or a 1-wire host controller, connected to the microcontroller. (The difference is whether you want to write your own 1-wire protocol code ... go with the host controller). You'll get a digital value for the temp, no ADC required.
