USB-ProxSonar-EZ1 MB1414 Ultrasonic Distance Sensor

USB‑ProxSonar‑EZ1 (MB1414) ultrasonic proximity sensor provides reliable people and obstacle detection through a simple USB interface while delivering one‑inch resolution distance data. This USB ultrasonic ranging module combines proximity triggering with continuous range reporting, enabling responsive detection of nearby targets inside a calibrated sensing zone. Designed for interactive installations, robotics safety detection, and automation monitoring, the compact sensing unit reports both presence and measured distance to the closest object. Support for multiple simultaneous units allows scalable deployment, while compatibility with external sensor mounting configurations ensures flexible integration into embedded systems, kiosks, and smart environment monitoring applications.

USB Interface for Rapid Integration

Built around a straightforward USB communication interface, this ultrasonic ranging module outputs serial distance data without complex wiring or analog signal conditioning. The digital interface simplifies connection to computers, embedded controllers, or industrial monitoring systems that require plug‑and‑play sensor deployment. One‑inch measurement resolution enables precise detection of nearby targets, supporting applications where consistent proximity feedback is essential, including interactive displays, automation triggers, and safety detection in smart environments.

Calibrated Proximity Detection Zone

This proximity sensing unit is optimized to detect people or objects entering a defined sensing region. A detection zone of approximately five feet allows reliable presence recognition while minimizing distant interference. Target acquisition typically occurs within about 2.5 seconds, while targets leaving the detection region are released after roughly 1.5 seconds. Such calibrated response timing allows stable presence monitoring in environments such as exhibition kiosks, access control triggers, or occupancy‑aware installations.

Long‑Range Ultrasonic Measurement with Multi‑Sensor Capability

A 42kHz ultrasonic transducer enables distance measurement up to 125 inches (318 cm) while maintaining consistent proximity detection within the 60‑inch active zone. The sensing board supports automatic multi‑sensor operation, allowing eight or more modules to function simultaneously depending on mounting conditions and surrounding acoustic environment. This capability supports large installations such as interactive exhibits, robotics awareness systems, and distributed obstacle detection networks.
