About One Wire Temperature Sensor - DS18B20 Pinout DS18B20 temperature sensor has three pins: GND pin: needs to be connected to GND (0V) VCC pin: needs to be connected to VCC (5V or 3.3V) DATA pin: is 1-Wire Data bus. It should be connected to a digital pin on Arduino. The ...
Arduino要实现对DS18B20的操作,需要OneWire和Dallas Temperature Control两个库文件,下载地址分别为:http://playground.arduino.cc/Learning/OneWire和https://github.com/milesburton/Arduino-Temperature-Control-Library。Dallas Temperature Control函数库是基于OneWire函数库进行开发的,更便于使用,下面讲解一下主要函数的功...
Now we create our Dallas Temperature sensor object by passing our OneWire reference into the class. OneWireoneWirePin(temp_sensor);DallasTemperaturesensors(&oneWirePin);Copy In our setup function, weactivate the Arduino serial interfaceso we can monitor the output lines in the code. This is als...
