Tutorial 3 Upload the data of temperature and humidity by Si7021

You need to have:

1. DeviceBit E-KIT(X1) with quick-plug-shield

2. Si7021 Sensor

3. An account on DeviceBit.com (http://www.devicebit.com/home/login)

You need to get these things ready:

1. Add 2 sensors on the website. One is the temperature sensor, and the other is humidity sensor just below your device “01”, and remember to untick Yes (set your device’s “controllable” to “No”), because we’ll not control our device at this moment. Edit their ID to “T1” and “H1” respectively, for we will need them in our codes later.

2. Download the arduino IDE from www.arduino.cc. Remember to select the version 1.0.5, not the latest version 1.5.0 by now.

3. Plug E-KIT to usb port and install the drivers using the Arduino UNO .

OK, here comes the tutorial.

1. 1. Download 2 libraries from github.com for free:

https://github.com/DevicebitDemo/DeviceBitHttpClient

https://github.com/yangbo1979/si7021

Put them to your arduino library directory, such as d:arduinolibraries

2. Open arduino IDE now,

Select File->Examples->DeviceBitHttpClient->Upload_Temperature_Humidity_Using_Si7021;

Replace ” #define LW_USERKEY "###############################" “ with your userkey in the user center of DeviceBit My account->Account settings.

3. Connect the wires of Si7021 to the E-KITShield, please refer to the following pictures.

4. Upload codes to E-KIT, and plug network cable to E-KIT. Your sensor’s value should on the website now.
