Centralized Monitoring of DHT22 Sensor Data – From Raspberry Pi to the Elastic Stack
Keeping an eye on the environment inside your server room – using temperature and humidity values from DHT22 sensors collected via Raspberry Pis. That’s exactly what I implemented in this project, including integration into an existing ELK platform.
What started as a simple Plotly-based visualization of sensor data quickly evolved into a more robust setup. Sensor integration became part of a full-fledged Elastic Stack architecture that I had previously set up for centralized logging of servers, firewalls, and network devices.
