Advanced 79GHz Traffic Sensor | Filters Rain & Sunlight | For Automated Gates Safety or Trigger

Product Overview: 

The RD79-6M Advanced 79GHz Traffic Sensor is a robust millimeter-wave solution engineered for high-performance vehicle detection in the most challenging outdoor environments. Unlike traditional optical sensors, this radar utilizes high-speed digital processing to filter out interference from rain, snow, and direct sunlight, ensuring 24/7 operational reliability. With an IP66-rated enclosure and an industrial-grade operating temperature range of -40°C to +80°C, it maintains a rapid 100ms response time regardless of weather conditions. This makes it an ideal traffic sensing component for automated gates, where stability and environmental immunity are critical for maintaining smooth traffic flow.

Designed for maximum versatility, this sensor serves as a comprehensive solution for both gate safety and trigger applications. Through the "GL Control" App, users can easily toggle between Safety Anti-Pinch Mode to protect pedestrians and vehicles, or Trigger Mode for automated gate opening. In trigger applications, the radar features advanced direction recognition and the ability to completely ignore pedestrians, preventing false cycles and enhancing security against unauthorized entry. With a precision-adjustable range of 0.2m to 6m, the RD79-6M provides a flexible, smart alternative to ground loops and infrared photocells for any modern passage control system.

Feature

• High-precision millimeter wave technology: Adopting the 79GHz frequency, it has extremely strong environmental adaptability and is not affected by rain, snow, dust, or strong light.
• Pedestrian filtering function (Vehicle Detect Only): It can accurately identify and ignore pedestrians within the detection range, effectively replacing traditional ground sense coils and eliminating the trouble of road-breaking installation.
• Direction recognition function: Supports direction detection, which can effectively prevent vehicles from "reversing" into the exit and improve safety.
• APP intelligent parameter adjustment: It supports parameter setting and calibration through the mobile phone "GL Control" APP, with intuitive and simple operation.
• IP66 protection level: Industrial-grade waterproof and dustproof design ensures long-term stable operation in harsh outdoor environments.
• Response and Power Consumption: Response time ≤ 100ms, average power consumption is only 1.2W (12V), energy-saving and efficient
• Detection Performance: Detection length is 1-6m, 0.5-1.5m on each side, supporting dual target detection of people and vehicles

Key Advantages of 79GHz Barrier Radar

1. High Precision and Fine-Grained Detection

Operating at a higher frequency ($79text{ GHz}$) provides a wider bandwidth, which results in superior range and velocity resolution.

• Target Recognition: It can distinguish between small objects, such as pedestrians, bicycles, and motorcycles, which are often missed by traditional loops.

• Accurate Triggering: It creates a precise "virtual curtain" that eliminates dead zones, ensuring the barrier never drops when a person or vehicle is directly underneath.

2. Directional Discrimination (Advanced Logic)

As we discussed, the ability to sense the direction of motion is a game-changer for traffic management.

• False Trigger Suppression: It ignores traffic moving away from the gate or walking parallel to it, preventing the barrier from staying open unnecessarily.

• Flow Control: Enables strict one-way access control by only responding to "approaching" targets, enhancing security in restricted areas.

3. Non-Intrusive Installation (Cost-Efficient)

Unlike inductive ground loops, radar is a surface-mounted technology.

• No Road Cutting: There is no need to excavate the pavement to bury wires, which preserves the integrity of the road and significantly reduces labor costs.

• Rapid Deployment: Installation and maintenance can be done in minutes without closing the lane for extended periods.

4. All-Weather Reliability and Durability

The 79GHz millimeter-wave technology is highly resistant to environmental interference.

• Environmental Immunity: It operates reliably in total darkness, direct sunlight, heavy rain, snow, and fog, where optical sensors (like infrared or cameras) often fail.

• Longevity: Since the device is housed in a protected casing on the barrier itself, it is not subject to the mechanical wear and tear caused by heavy vehicles driving over it (a common cause of ground loop failure).

5. Intelligent "Human-Vehicle" Differentiation

Modern 79GHz radars use sophisticated algorithms to categorize objects.

• Safety First: The radar can identify a pedestrian's unique "micro-doppler" signature. If a child or a pet follows a car into the detection zone, the radar will maintain the "stop" signal to prevent injury.

• Adjustable Zones: Users can digitally configure the detection length and width via software or mobile apps to fit narrow or wide lanes perfectly.
