I am fairly new to the IoT world, so I need help designing a system.
Scenario: I have an application that sends messages to a Service Bus/ Message Queue in Azure. The messages can be classified into three categories:
- CryForHelp [Urgent Issues]
- Applaud [Someone did a great job]
- Sad [Someone needs help not urgent]
Based on the type of message sent to Service Bus I want to play a sound using some IoT device (speaker or siren). Since I am only looking for 3 categories of sounds even if it is not a speaker it is okay.
Cost Requirements: I am looking for a small IoT device that will cost less than $30 so that I can place it in our office area.
Hardware requirements: It can be operated through Restful APIs so that I can integrate it with the Azure Service Bus.
Can someone point me into the right direction? I am not sure what is the right way to design this? Also, what type of Hardware should I be looking for?
