Recorded today, a brilliant talk with Marie Cruz, Senior Developer Advocate at Grafana Labs — coming soon to Ministry of Testing!

In “STEM in the garden: How to monitor plants with IoT sensors and Grafana Cloud”, Marie shares how an at-home STEM project with her daughter, using a soil moisture sensor and Grafana Cloud, became a fun and practical way to explore monitoring, observability, Prometheus, IoT, and more!

“Monitoring is checking the plant’s health. Observability is understanding why it’s changing.”
— Marie Cruz

A beautifully simple explanation, rooted in real-world learning.

This talk is not only a fun STEM activity for families to try (and a clever way to remind your kids to water the plants!), but also a valuable starting point for testers looking to build confidence in monitoring, observability, and system health; skills that help drive better questions and deeper collaboration in teams.
