The DS18B20 Digital Temperature Sensor Module utilizes the popular 1-Wire DS18B20 temperature measurement IC.
Communication with the DS18B20 is via the 1-Wire serial interface. There is an LED on the module that flashes when the sensor is communicating with an MCU.
The communication protocol can look daunting when looking at the datasheet, but fortunately most poplar microcontrollers like Arduino have software libraries that make using these devices very straightforward and easy to do.
There are some options which can be programmed when using the device such as choosing between number of bits of resolution vs conversion time, but those can be ignored for establishing basic operation.
Hookup is straightforward. Just supply power, ground and connect the 1-Wire bus pin to a digital pin on the microcontroller. The part is compatible with 3.3 or 5V power.
There is a 3-pin header on the assembly. There are a couple of different labeling schemes used on these modules as the baseboard is used for several different modules.
1 x 3 Header
This is a basic module that can be used in a number of different applications where temperature measurement is useful such as determining when a cooling fan should be turned on.
We also offer the DS18B20 device in a number of other packages including as a bare IC for designing your own circuits, a waterproof version and others.
The software below implements basic communications with the sensor using the 1-Wire bus protocol and provides a read-out of the sensor output. We use pin 4 in the example, but this can be reassigned to any digital pin.
The program uses the OneWire and DallasTemperature libraries that can be installed from the IDE Library Manger.
This shows an example output from the program.
