A DS18B20 digitális hőmérséklet-érzékelő modul láncolható, Arduino-kompatibilis, egybuszos sorozatba csatlakoztatható
DS18B20 Digital Temperature Sensor Module Chainable Can be Connected in Series Single-Bus Sensor Compatible for Arduino
Description
The module (Digital Temperature Sensor) is based on the digital temperature sensor module DS18B20 single bus. 
Due to a single bus interface allows multiple DS18B20 mounted on the same bus, and the on-board interface to facilitate multi-point temperature, the use of multiple digital temperature sensor module can achieve a signal line measuring a large area multi-point temperature.
Pullup resistor on the board can be directly connected to most microcontroller, the measured temperature range of -55 ~ 125 , the accuracy of which is in the range of -10 ~ 85 ± 0.5 , widely used in buildings, equipment , machinery, greenhouses and other temperature measurement and control.
Features
1 On-board switch can be set on a pull-up resistor is connected, multi-point temperature measurement applications, usually as long as a pull-up resistor to pull-up resistor should be disconnected on the remaining temperature measurement module.
2 single bus communication, multiple modules can share a data cable
3. Supply voltage of 3.3 ~ 5.5V
4. Thermometer resolution procedures available to select from 9 to 12, the higher the resolution, the longer the temperature conversion time
5.4 M2 screw positioning holes for easy installation
Interface
Control Interface: A total of three pins (GND, VCC, SIG), GND to ground, VCC is the power supply, SIG is a single-bus communications signal pin; 
Bus common interface: a cascade of similar usage for multi-point temperature, without the need for each group of lines are connected to the main control board. 
Switch: If you are a single point temperature, it should be appropriated PULL-UP end of the handle, pull-up resistor connected to the 4.7K; If it is multi-point temperature measurement, temperature measurement module is more than just a pull-up resistor module the rest are appropriated for the other side. 
Temperature sensors: 2013 of DS18B20, single-bus digital temperature sensor; 
Positioning holes: 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination;
