Your device is covered in senses you don't have. This page wakes every one it can find — accelerometers, magnetometers, light meters, microphones, radios — and turns their whispers into something you can see. Nothing leaves the device.
Some senses need a tap and a permission prompt — that's the browser protecting you. Best on a phone, over HTTPS.
Anomaly level 0%
Calibrate while the device rests still, then watch what moves when nothing seems to.
Point an infrared remote at the camera and press a button — most phone cameras see the beam your eyes cannot.
Nothing has stirred yet. Awaken the senses and every spike lands here with a timestamp.
A snapshot of the capability list, the latest readings, the baseline and the log — generated in the page, never uploaded.
