The TICK Stack is a powerful tool for building IoT projects, especially when combined with the Google Cloud Platform. Kapacitor, part of the TICK stack, is a stream and batch processing engine that can be used to monitor data in real-time. In this tutorial, we have set up Kapacitor on the Google Cloud Platform to create an alerting system for temperature data from IoT sensors. We defined a task using TICKscript, which logs high temperatures to a file and sends notifications to a Slack channel when the temperature exceeds 30 degrees Celsius. The integration of Kapacitor with the Google Cloud Platform provides a scalable and reliable solution for building IoT projects.
