for more than 10 seconds while no target is present inside the window boundary. Maintenance and Legacy System Retrofitting
Unlike standard USB peripherals, the Wu 102 does not use a generic CDC (Communications Device Class) driver. It requires a specific INF file and low-level access to configure advanced parameters such as:
| Feature | Microsonic WU102 (Legacy Product) | Microsonic Ultrasonic Sensors (Core Business) | | :--- | :--- | :--- | | | High-Power Wireless USB Adapter | Industrial Ultrasonic Sensors & Controllers | | Primary Purpose | Extend Wi-Fi range (up to 1km) | Detect, measure, and position objects in automation | | Key Feature | High-gain (5dBi) antenna for long-range | Immune to color, transparency, dust, and dirt | | Current Status | Discontinued (as of Dec 2015) | Active and Expanding – A global market leader | | Target User | Consumer / Small Office | Industrial engineers, system integrators, OEMs | | Driver Status | Extremely difficult to find; try legacy archives or search for "WU101" replacement driver | Integrated into industrial networks (IO-Link) or controlled via LinkControl software |

—is engineered for localized, contact-free distance monitoring in harsh environments: 200 kHz
Analogue distance measurement ranging between 200 mm to 2,000 mm .
What if you cannot obtain the official driver (e.g., end-of-life support or corporate IT restrictions)?
Used for sensors manufactured before 2018. This driver creates a standard COM port (e.g., COM3) that allows legacy software like or u-Link to communicate via RS232-to-USB converters.

The easiest way to map the analog output window is by using the two physical push-buttons located on the rear of the sensor housing:
Because the sensor uses sound rather than light (like photoelectric sensors), it is impervious to target color, transparency, or ambient light conditions.
