PB-000090 – Social Distancing Tag System

The social distancing tag reference design showcases Chirp’s CH101 ultrasonic Time-of-Flight (ToF) sensor for social distancing and proximity detection applications. Using Pitch-Catch mode operation, the distance between multiple users can be measured accurately, and any encroachments within the ‘safe distance’ boundary can be flagged as an alert. These tags, which use two CH101 sensors to achieve 360° field-of-view, will send out an alarm (via haptic and visual feedback) when another user wearing a tag approaches within the configurable boundary distance (2.4m max).
