Many modern pieces of equipment post data to the Internet, but utilizing that data in meaningful ways can be cumbersome.
With Composer, you can easily create an app that lets you access incoming data from Internet-connected pressure gauge and create automatic alerts when the pressure values exceed safe limits.
We start by defining an external trigger in Composer. This gives us an API endpoint (a secure web address) that can accept incoming data from the pressure gauge. We set up the pressure gauge to post data to the external trigger endpoint and define how often data is submitted.
We then set up Composer to use the incoming data to create a new “Pressure Gauge Reading” record for each reading. Accessing past pressure data is immediately available via a list. We can also show a graph of the pressure over time.
Finally, we set up an Automation trigger to send a push notification to a maintenance engineer immediately when the app receives a new reading where the pressure value is above a limit we choose.
