FAQ of DS18B20 Temperature Sensor
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.
