Parking Guidance Gateway | IoT Edge Controller for Smart Parking Signs and Sensors

The Parking Guidance Gateway is what turns two signs and a handful of sensors into an actual parking guidance system. On its own, each counter or bay sensor only knows its own small piece of the picture. The gateway is the edge controller that collects all of those pieces, computes the numbers that matter, and tells every sign what to display, all in real time.

It aggregates inputs from entry/exit vehicle counters and in-bay occupancy sensors across multiple lots, zones, and levels. From those inputs it runs the “spaces free” logic locally at the edge: capacity minus live occupancy, per zone, updated the instant a vehicle enters or leaves. Because the calculation happens on the device, guidance stays fast and accurate even if the internet connection drops, and the gateway buffers data and auto-syncs to the cloud once connectivity returns.

The gateway then pushes live updates to every guidance sign over MQTT and Modbus TCP, so the Smart Parking Flip-Dot Guidance Signage and IoT Indoor LED Signage Display always show current numbers and directional arrows. The same data is exposed over HTTP / JSON APIs for your mobile app, dashboard, or third-party parking platform, and can feed SCADA and cloud systems.

Designed as an industrial node, the gateway ships in a rugged DIN-rail, IP-rated enclosure, runs on 9-36V DC, and supports Ethernet, Wi-Fi, and optional 4G. It is the single piece that makes the whole loop a “system” rather than a set of disconnected parts, and it scales from one entrance to an entire multi-level structure. Deploy it your way – on-prem, private cloud, or IoTize SaaS – with OTA updates and your data, your way.

Key Features

• Sensor and Counter Aggregation – Collects data from multiple entry/exit vehicle counters and in-bay occupancy sensors into one live model of the site.
• Edge “Spaces Free” Logic – Computes capacity minus occupancy per zone and level on-device, for instant, network-independent guidance.
• Drives Every Sign – Pushes real-time counts and directional arrows to all guidance signs over MQTT and Modbus TCP.
• Multi-Zone / Multi-Level – Manages many lots, zones, and levels from a single controller, each with its own capacity and rules.
• Offline Resilience – Local processing plus data buffering keeps guidance live during network dropouts; auto-syncs on reconnect.
• Open Integration – HTTP / JSON APIs, MQTT, and Modbus TCP for apps, dashboards, SCADA, and third-party parking platforms.
• Threshold and Event Rules – Configurable rules for “lot full”, zone rerouting, and operator alerts.
• Secure and Manageable – Role-based access, encrypted connections, and OTA firmware updates.
• Flexible Deployment – On-prem, private cloud, or IoTize SaaS; data freedom, never locked to our servers.
• Industrial Build – Rugged DIN-rail, IP-rated metal enclosure for control rooms, risers, and equipment cabinets.

Technical Specifications

Applications in Detail

• Multi-Level Garages – Aggregate every ramp counter to publish accurate free-space counts on each level’s signs.
• City and Municipal Parking – Coordinate multiple lots across a district into one occupancy view and one set of guidance signs.
• Shopping Malls and Mixed-Use – Route drivers between zones by pushing live availability to entrance and in-garage signs.
• Corporate Campuses – Separate employee, visitor, and reserved zones, each with independent capacity and rules.
• Hospitals and Airports – High-turnover sites that need reliable, low-latency guidance even during network interruptions.
• Retrofit Projects – Add the gateway on top of existing counters and sensors to upgrade a legacy lot into a live guidance system.
