The DS18B20 is a digital temperature sensor that can communicate over a 1-Wire bus, which means it requires only one data line (and ground) for communication with a microcontroller. One of the features of the DS18B20 is that it can be powered in two different ways: conventional power mode and parasite power mode.

Q: Where physically on the device does the temperature measurement take place?
A: The DS18B20 does not sense temperature directly through the package. For all package types, the DS18B20 senses temperature primarily through the GND pin. Ensuring a good thermal connection between the GND pin of the device and the heat source you wish to measure will provide the best results.
Q: Is there a way to extend the temperature range of the DS18B20?
A: No, there is not a way to increase the range it reads. The DS18B20 reads with an accuracy of ±0.5°C from -10°C to +85°C and ±2°C accuracy from -55°C to +125°C.
Q: Will a conformal coating affect the thermal response of the DS18B20?
A: A thin conformal coating will not affect the thermal response of the device.
Q: Using OneWireViewer, can more than one DS18B20 be logged?
A: Yes, every DS18B20 will have a file where you can store the data. Data will be received from one DS18B20 at a time.
Q: Can you power the DS18B20 from a 3V battery?
A: The DS18B20 can be powered from any source. Since batteries will dip in voltage, a nominal 3V battery may not always supply the minimum 3.0V the DS18B20 requires. We suggest a step-up voltage regulator is used to ensure the device is supplied within its rated voltage range of 3.0V to 5.5V.
