“ICU-10201 gives the sensitivity required for impediment avoidance or proximity sensing, which is used continuously in robotics, drones and robotic vacuum cleaners,” in keeping with the corporate. “The sensor offers millimeter-accurate vary measurements to targets at distances as much as 1.7m, in any lighting situation together with full daylight, independently of the goal’s shade and optical transparency, like glass or mirrors.”
1.7m is to a wall, lowering to 1.1m for a 58mm diameter publish. Accuracy is affected by the velocity of sound’s 0.2%/°C drift. Minimal vary is 100mm, though objects may be detected, and typically ranged, all the way down to 30mm.
The chip is 1.26 mm tall and its prime has a central sound port whose field-of-view is roughly hemispherical, however may be diminished utilizing an exterior horn the place rising diameter leads to slim beams – the corporate gives design knowledge for a number of horns. Sonically operation is nominally 175kHz – resonance varies throughout 173 to 181kHz via manufacturing tolerance.
