Traffic Environment Sensors

Traffic environment sensors are dedicated devices for road, highway and tunnel environmental safety monitoring, supporting smart transportation infrastructure construction across different regions. This category contains highway weather station, road state sensor, tunnel environment sensors and transmissometer. These traffic environment sensors keep tracking critical parameters such as road surface ice, water film thickness, atmospheric visibility, smoke concentration and tunnel air quality 24/7. Rugged enclosure protects internal components against strong wind, heavy rain and vehicle exhaust pollution in roadside and tunnel environments. Collected data feeds into traffic management systems to support fog warning, icy‑road alert and tunnel ventilation control. Our traffic environment sensors are widely deployed on expressways, mountain tunnels and urban arterial roads, helping traffic authorities reduce weather‑related traffic risks and improve overall road operation safety.

HY-RSS13E Road State Sensor, Optical Non-invasive Road Surface Sensor Detecting Ice, Snow, Water Film and Pavement Temperature for Road Weather Station and ITS Intelligent Transportation

HY-RSS13E is a non-contact road surface state detector, thanks to its remote sensing technology, it can not only avoid damage to the road, but also traffic interference during its installation. Multispectral measurement technology enables accurate detection of thickness of ice, snow, water on surface of the road.

HY-RSS11E Non-Contact Road State Sensor, Multispectral Detector for Pavement Ice, Snow & Water Monitoring

HY-RSS11E is a non-contact road surface state detector, thanks to its remote sensing technology, it can not only avoid damage to the road, but also traffic interference during its installation. Multispectral measurement technology enables accurate detection of thickness of ice, snow, water on surface of the road.

HY-MRVS2E Vehicle-Mounted Visibility & Road State Sensor, RWIS Monitoring Sensor Highway Mobile Road Weather Survey and Winter Maintenance Assessment

HY-MRSS2E Mobile Road Sensor, Remote Sensing Pavement Detector for Highway Ice & Snow Monitoring

HY-MRSS2E uses remote sensing technology to quickly and real-time detect the state types and accumulated thickness of ice, snow and water on the road surface. It is mainly used to provide decision-making basis for road maintenance and safety control in winter.

HY-IRS2E Non-Contact Infrared Temperature Sensor for Road Surface and Canopy Temperature Monitoring

HY-IRS2E is a compact infrared temperature sensor. The optical analysis system is sited in a compact aluminium shell. An 90° adjustable mounting bracket allows an easy installation. It’s designed for industrial, outdoor 7/24 monitoring.

HY-WTE Tunnel Ultrasonic Wind Sensor, High Precision Ultrasonic Anemometer Measuring Wind Speed and Direction for Highway, Railway and Subway Tunnel Ventilation System

HY-WTE crossed type tunnel ultrasonic wind speed and wind direction detector is specifically designed for for the tunnel application, it’s working based on ultrasonic time-difference method, the two ultrasonic probes were installed on both sides of the tunnel wall and face to each other, when tunnel airflow passes between the two ultrasonic probes, the time difference between the round-trip times of the ultrasonic waves transmitted by each other is changed by airflow. By measuring the time difference, the airflow velocity is obtained.

HY-WDS21E Tunnel Wind Speed Sensor, High Precision Tunnel Anemometer for Real-time Air Velocity Monitoring in Highway, Railway Tunnel Ventilation System

HY-WDS21E Ultrasonic Anemometer uses highly stable ultrasonic probes to simultaneously measure wind speed and direction based on principle of TOF(time of flight) of ultrasonic sound wave. It’s specially designed for the tunnel application, it’s installed on the tunnel wall and providing real-time tunnel wind data to total control room, as a basic basis for ventilation and operation.

HY-TWSE All-in-One Highway Weather Station RWIS Monitoring Station Equipped with Visibility MOR Meter and Road Surface State Sensor for Highway and Bridge Road Weather Information System

HY-VIE Tunnel Visibility Sensor Transmissometer with CO NO NO2 for Highway Road Tunnel Ventilation Monitoring

HY-VIE Tunnel Visibility Sensor is a professional-grade atmospheric visibility monitoring instrument, purpose-built for road, highway, railway, and mining tunnel environments. It continuously measures visibility distance in real time, giving operators the critical data needed to detect fog, haze, dust, and exhaust-induced air pollution inside tunnels — where visibility can change within seconds and directly threaten driving safety.

HY-LXP21E Tunnel Entrance Luminance Sensor, Brightness Photometer for Highway Tunnel Lighting Control

HY-LXP21E measures the level of illuminance within the tunnel and report it to lighting control center, so that lighting strength within the tunnel can be precisely adjusted to ensure illuminance within tunnel is close to luminance of entrance and exit of tunnel.
Designed specifically for the tunnel environment, the HY-LXP21E continuously measures cosine corrected planar illuminance within the tunnel thus allowing elimination of directional error.

HY-CDP22E Tunnel Entrance Luminance Sensor, Brightness Meter for Highway Tunnel Lighting Monitoring

HY-CDP22E tunnel entrance & exit luminance sensor measures the level of luminance, also called as brightness, created by natural light at the tunnel entrance / exit to ensure that the visual perception of drivers will be maintained, both day and night, by avoiding sudden variations in lighting levels and potential "black hole effect" when entering and exiting a tunnel.
