DS18B20 1-wire Digital Temperature Sensor Module

The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius  temperature  measurements  and  has  an  alarm function  with  nonvolatile  user-programmable  upper and lower trigger points. The DS18B20 communicates over a 1-Wire  bus  that  by  definition  requires  only  one  data  line  (and  ground)  for  communication  with  a  central  micro-processor.  In  addition,  the  DS18B20  can  derive  power  directly  from  the  data  line  (“parasite  power”),  eliminating the need for an external power supply.

All the work is done, the board has the 4k7 resistor in the circuit along with a power-on LED. Simply connect jumper wires to GND, data (DQ) and VCC (between 3.3V and 5V DC, so ideal for Raspberry Pi and Arduino, amongst other platforms).

Features:

•      Support voltage: 3V~5V
•      Temperature measurement range: -55'C~125'C
•      Resolution:9~12 digits under -10'C~85'C
•      Accuracy: +/- 0.5'C
•      Temperature sensor
•      Great for electric product DIY lovers
•      9-bit to 12-bit thermometer resolution
•      Useful for reading temperature directly in MCU which are without ADC.

Applications:

•     Home and office
•     Temperature sensitive projects
•     Industrial process control systems
