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...
在Arduino IDE中对DHT11温湿度传感器进行编程控制的前提是要安装DHT.h库，首先依次点击菜单“项目”-“加载库”-“管理库”项，在弹出的“库管理器”中以“DHT11”为关键词进行搜索，会出现一个名为“DHT sensor library(by Adafruit)”的库，显示支持DHT11（目前最新版本为1.4.2）；接着，点击“安装”按钮（...

Re: My Temperature Sensor Yeah I am using the 1-Wire DS18B20. It works great for me, although now that I am thinking about it, i have never actually compared it to a control device to check the accuracy. The Arduino has a library available that will convert the reading into F/C ...
In your Arduino sketch, include the PH4502C Sensor Library by adding the following line at the top of your code: #include<ph4502c_sensor.h> Create an instance of thePH4502C_Sensorclass: PH4502Sensorph4502c(A0, A1);//Analog Pin 0 - pH level pin//Analog Pin 1 - temperature pin ...
Arduino Library for Microchip MCP9808 Maximum Accuracy Digital Temperature SensorA lightweight implementation that exposes all functionality of the Microchip MCP9808 sensor. Temperatures are handled in the integer domain to avoid the code size and runtime overhead associated with floating-point. Should ...
