I need a single QR code that will live on my printed materials and, whenever it’s scanned from an Android device, open a specific webpage in the phone’s browser.

I need a straightforward concept that lets a cylindrical sensor (≈12-16" tall, 2" Ø, 3-6 lbs) hang securely above a square 19" × 19" tank opening without touching or modifying the tank itself.

The mounting style can be a hook, clamp, or even a magnetic arrangement—whichever solution offers the most reliable grip while keeping the sensor perfectly vertical and stable. Likewise, the actual attachment method to the tank rim is flexible; the only non-negotiables are quick, tool-light installation and equally easy removal so the whole rig remains truly portable. Please deliver: &bu...
