ParkSen® Ultrasonic Parking Space Detector
The ParkSen® is a revolutionary ultrasonic detector designed for modern smart parking lots. Installed at the front of each parking bay, it uses high-precision ultrasonic technology to instantly determine a space’s occupancy status. High-brightness LED indicators, with support for multiple color settings, make it easy for drivers to spot open spots briefly. Integrated with a smart parking guidance system, ParkSen® significantly reduces the time drivers spend searching for a space and minimizes congestion. For uniquely shaped parking bays, an auxiliary display light can be connected, offering flexible solutions for any garage layout. The detector also communicates in real-time with the PSC-064 Zone Controller, sending all parking status information back to the ParkHelper® Parking Management Host. This seamless integration allows the system to analyze and update availability, creating a highly efficient smart parking environment.
Key Features
All-in-One Design
Combining an ultrasonic transceiver and LED indicator in a single unit, this streamlined design simplifies the installation process and reduces construction time.
100% Status Detection
Even if the network is down or the zone controller or management host fails, the ultrasonic detector continues to monitor the parking space, updating the LED light in real-time.
Front-Mounted Detection
Installing the device at the front of the parking bay eliminates the need to access the space for installation or maintenance. This prevents disputes over vehicle damage and ensures uninterrupted service.
Automatic Configuration
The auto-ID position setting function saves significant time and prevents human error. The device also features a self-check function, alerting the zone controller and management host if an LED light is damaged, enabling quick notification for maintenance staff.
High Accuracy
Under proper installation conditions, the parking space occupancy recognition accuracy rate can reach over 99%.
Self-Diagnostics
Built-in features provide error alerts for wiring faults and an automatic bypass function for device damage. This significantly reduces system troubleshooting time. Even with a wiring fault, the device continues to detect and update the space status.
Quick Installation
The ultrasonic detectors support a series wiring method, using a two-core signal wire and power cable to connect up to 40 detectors over a transmission distance of up to 1,200 meters.
Customizable LED Colors
The built-in 7-color LED indicator allows users to define color-matching relationships for different types of spaces. For example: purple for VIP spots, blue for handicapped spots, etc.
Low Power Consumption
The ECO energy-saving design keeps the device’s power consumption below 0.5 watts, supporting green and sustainable parking initiatives.
Anti-Interference
The built-in anti-interference circuit design effectively reduces false readings caused by external environmental factors.
