Using IBM Bluemix

www.azilen.com 02
What is IBM Blue-mix?
IMB Bluemix provides readily available environment for applications,
infrastructure and services. Integrated with IBMWatson, it offers possibilities of
cognitive services as well.
We have developed an IoT application using IBM Bluemix, Raspberry PI – 3 and
a virtual device that sends email notifications to user as and when there is a
fluctuation in temperature.
Process flow: Virtual device will be placed at desired location >> If temperature
at that location rise more than 21 degree centigrade, the user will simply get
notification about it by email.
This blog is a step by step guide to develop temperature sensor IoT application
and it includes:
• Virtual device & Raspberry PI integration with IBM Blue-mix
• Register Virtual Device and analyze the device data
• Register Raspberry PI – 3 and analyze the device data
• Linking Raspberry PI with our device through IBM Bluemix
