DS18B20 Instead of reading a voltage with an analog pin, we read a
serial stream of bits from the sensor on one of our digital pins.
One such sensor is the Dallas Semiconductor DS18B20. It uses what
Dallas Semiconductor calls the OneWire protocol to communicate back
and forth between the sensor and the tiny computer. It has three
pins, one for power, one for ground, and one for the data link (it
is this single data link line that gives the protocol its name).
DS18B20 is a commonly used digital temperature sensor, and its
output is digital signal. It has the characteristics of small size,
low hardware overhead, strong anti-interference ability and high
precision.
Votesen VTS200 is a DS18B20 digital temperature sensor which
composed of original DALLAS chip, stainless steel probe, cable and
connector.

PRODUCT FAQ
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.
