AWS Lambda function/application invoking Airly API to get some basic information about current air quality.
Lambda code is writen in Python and is rather easy to understand. As it only calls API and filters the result.
Full information about at all indexes, pollutants and weather conditions. Example of email received when there is bad air quality at location named Home:
Only basic information, about main index value, percentage of pollutants indexes, and weather conditions. Example of SMS received when there is good air quality at location named Home.
Infrastructure part can be easily deployed with Terraform with already existing definition. It's meant be just an example of implementation, hence S3 bucket used for Lambda package will be created and destroy by default. For simplicity Terraform backend is set be local only, so don't run it in a container or untrusted host, because you may loose or expose your tfstate file. To adjust it to your existing infrastructure some Terraform basic knowledge is necessary.
Follow instruction in AWS documentation.
Create secrets.tfvars
file and put there your values as in example below.
For more details see description of those variables in variables.tf
.
Example shows value that you NEED to set, other values can be overwritten if you like.
