USB-ProxSonar-EZ MB1414 Ultrasonic Distance Sensor

USB‑ProxSonar‑EZ ultrasonic proximity sensor provides reliable human and object presence detection through a simple USB interface. Designed for rapid integration into computer‑connected sensing systems, this ultrasonic detection module connects directly through a standard Micro‑B USB cable and reports when a target enters or exits the calibrated sensing zone. A 42kHz ultrasonic transducer measures distance with 1‑inch resolution while maintaining a wide detection field of up to 125 inches. This USB‑based proximity detection solution supports multi‑sensor operation, allowing multiple ranging units to operate simultaneously for scalable installations such as interactive systems, occupancy sensing, and intelligent automation projects.

Direct USB Connectivity for Rapid Integration

Integrated USB communication enables straightforward connection between the ultrasonic ranging hardware and a host computer without additional interface circuitry. This computer‑connected proximity sensing module uses a standard Micro‑B USB cable for both power and communication, simplifying deployment in kiosks, interactive displays, or embedded monitoring systems. The USB interface design eliminates the need for complex microcontroller configuration, allowing software systems to immediately receive presence and distance data from the ultrasonic detection unit.

Reliable Human Presence and Object Detection

A calibrated ultrasonic sensing zone enables accurate identification of objects such as people entering a monitored area. This ultrasonic presence detector acquires a target in approximately 2.5 seconds and releases the target about 1.5 seconds after the object leaves the detection region. Stable acquisition and release timing helps reduce false triggers while maintaining responsive detection. Such behavior makes the ultrasonic proximity module well suited for interactive installations, automated kiosks, and occupancy‑triggered electronic systems.

Wide Range Measurement with Minimal Dead Zone

A 42kHz ultrasonic transducer measures distances up to 125 inches (318 cm) while maintaining a defined detection zone of approximately 60 inches (152 cm). Measurement resolution reaches 1 inch, providing precise presence feedback for automation systems and interactive applications. The ultrasonic ranging device also features virtually no dead zone; objects closer than 6 inches are still detected and reported as 6 inches. Compact size and lightweight construction allow this ultrasonic sensing board to integrate easily into embedded products.

Common applications include human‑presence detection systems, interactive exhibits, smart kiosks, automated doors, robotics proximity awareness, and computer‑connected monitoring platforms requiring reliable ultrasonic distance sensing.
