Hamster Monitoring System
May 2025When we noticed our hamster, Mooey Maria Hazel, obsessively running on her wheel every night, we decided to find out just how far she was going. What started as a simple Raspberry Pi project quickly turned into a full-stack setup: we used a Hall effect sensor and magnet to track wheel rotations, added a DHT22 sensor for temperature and humidity, and wrote a Python script to send the data to a Next.js backend. The script runs as a systemd service, and the data powers a live dashboard showing Mooey’s activity. After some trial and error with enclosure design — especially since Mooey loves chewing things — we eventually built a safer, more stable system. Now we can monitor her nightly marathons in real time, blending hardware, software, and a lot of hamster love.
