In this lesson, we’ll show how to remote monitor the environment temperature and pressure value from Cayenne IOT platform.
2 Hareware preparation
|Osoyoo UNO Board||1|
|Ethernet Shield W5100||1|
3 Hareware connection
Connect the BMP180 with UNO as following diagram:
4 Add new device
Log in Cayenne IOT platform，Add new…->Device/Widget
Overhere we need add 2 widgets for the pressure and temperature as below:
Change the data:
Widgit Name: Give your actuator a name, the default name is BMP180；
Select Device:Select your Arduino device, the one used in this example is the Arduino Uno
Connectivity: Select your method of connectivity: There are Digital, Analog and Virtual. in this example we use Virtual;
Temperature Pin: V5;
Pressure Pin: V6;
Choose Widget: choose any one as you like;
Choose Icon: choose any one as you like.
When we did this tutorial, the official tutorial was not updated. So, please copy and paste the sketch into Arduino IDE(You can also download the sketch here), Before uploading the sketch , please make sure you have done the following step:
Choose the Board type Arduino Uno and correct Port, then upload the sketch to your Uno board. In the Cayenne dashboard, you can click”Step 2 :Add Sensor”, once finished, the temperature and barometer widgets will be displayed:
From the databoard,we can read the temperature is 27.00 Celsius Degrees and the barometer is995.62HPa. At the same time you can read the data from your Adroid/iOS smart phone no matter where you are.
