The Ultrasonic Parking Space Sensor with LED Indicator is a front-mounted, integrated parking guidance solution for accurate real-time monitoring of individual parking spaces. By combining an ultrasonic detector and LED indicator into a single compact unit, the sensor is installed directly above each parking space line to detect vehicle presence and visually indicate space availability.
When a vehicle occupies the parking space, the LED indicator automatically switches from green to red, clearly showing the parking status. Occupancy data is transmitted in real time via RS485 communication to the area controller, then processed by the central controller and displayed on parking guidance screens throughout the parking facility. At the same time, all parking data is stored in the management system database, enabling operators to monitor real-time availability and generate daily, monthly, and yearly parking statistics.
Compared with traditional split-type parking guidance systems, this integrated front-mounted design significantly reduces installation complexity, construction time, and overall project cost, while ensuring high detection accuracy, strong anti-interference performance, and long-term system reliability. It is ideal for underground parking garages, commercial complexes, office buildings, hospitals, and large-scale parking facilities.

Parking Guidance Application Overview
The detector is a core component of the parking guidance system. It integrates an ultrasonic sensing module with a built-in LED indicator and is installed directly above each parking space line. Using ultrasonic ranging technology, the detector continuously monitors parking space occupancy in real time, controls the visual indicator display, and transmits parking status data to the area controller via RS485 communication.
Each front-mounted ultrasonic parking space detector consists of an ultrasonic sensing unit and an integrated indicator light. The ultrasonic probe determines whether a parking space is occupied or vacant, while the LED indicator visually displays the parking status:
Green: Vacant
Red: Occupied
Blue: Fixed parking space
Purple: Reserved parking space
By integrating the detector and indicator into a single front-mounted unit, the system is installed directly above each parking space. Compared with traditional split-type ultrasonic parking guidance systems, this design significantly simplifies installation, shortens construction time, and reduces material and labor costs by eliminating separate indicator lights, additional conduits, and extra wiring.
Mounted on the cable tray or ceiling above each parking space line, the detector avoids column obstruction and delivers a clean, uniform, and professional installation appearance.
The detector features a dual-channel independent ultrasonic transceiver circuit, providing redundant operation and expanded detection coverage. This design improves detection stability, reliability, and service life. Multiple signal judgment methods and advanced intelligent anti-interference algorithms effectively eliminate ultrasonic crosstalk, adjacent vehicle interference, and environmental noise.
Designed for industrial-grade performance, the detector has undergone strict testing for static electricity, lightning strikes, surge protection, and electromagnetic interference, ensuring reliable operation in harsh parking environments with fluorescent lighting, large electromechanical equipment, and electrical surges.
Comprehensive electrical protection—including short-circuit, reverse-polarity, and miswiring protection—prevents equipment damage caused by incorrect wiring during installation. Plug-in terminal connections simplify wiring, reduce installation labor, and minimize risks of poor contact or short circuits.
External dual LED status indicators allow maintenance personnel to quickly identify device operating conditions at a glance, while internal LED indicators provide long service life and clear visibility.
The detector features a compact, modern industrial design and supports optional expanded functions, including passive switch input detection, switch output for parking locks or external devices, and parking space reservation functions (upgraded versions).
Installation & Configuration
Installation Guidelines
The front-mounted ultrasonic detector is installed directly above the parking space line. For optimal detection performance, the horizontal distance between the detector and the parking space line should be within 0–1.0 m, with 0.3–0.5 m recommended.
The recommended installation height is 2.0–3.0 m, with an optimal height of 2.5 m.
This installation method ensures accurate ultrasonic ranging while maintaining a clean and obstruction-free layout within the parking area.
Remote Configuration Method
The detector supports wireless remote configuration, replacing traditional DIP switch settings. Unlike conventional systems that require ladder access to adjust DIP switches, all parameters can be configured directly from ground level using a handheld remote controller.
This approach significantly improves commissioning efficiency, reduces installation time, and minimizes on-site labor.
Remote Configuration Procedure
- Power on the device. Initialization completes in approximately 1 second.
- Press the Lees button to view current parameter settings (optional).
- Use the directional keys to select the parameter to be adjusted, then use the “+ / –” buttons to modify the value.
- Press the Set button to confirm the changes. A blue LED flash indicates successful configuration.
