This lesson, we’ll show how to get environment temperature data fromm DS18b20 temperature sensor from browser or smart phone
|UNO R3 board||1|
|Ethernet Shield W5100||1|
Connect the DS18B20 temperature sensor with UNO as following diagram:
Step A)Install library: (if you have installed OneWire library and DallasTemperature Library, please skit this step)
Download these two libraries from:
Then in your Arduino IDE ->Sketch->Include Library->Add .ZIP Library and select these two zip files you just downloaded, and upload it to Arduino.
Step B) Download sample code from https://osoyoo.com/driver/ethernet_iot/lesson6/w5100-lesson6.zip, unzip the file and double click the w5100-lesson5.ino file, load the sketch into Arduino IDE.
Open your Serial Monitor, you can see your router will assign an IP address to your Arduino as following:
In above example, 10.0.0.45 is the IP address of my Arduino.
Now use another computer or your cell phone’s browser to visit url : http://10.0.0.45
Your browser will show following result:
