The Luminance Sensor is a versatile combined device that functions both as a sensor and a camera, specifically tailored for tunnel lighting management, object surveillance, and high-resolution photo transmission to a control room. It can be equipped with an optional night vision system and a built-in light level sensor, enabling effective monitoring of safety in dark or difficult-to-access areas within tunnels. By integrating sensor and camera functionality into a single unit, it ensures comprehensive situational awareness and supports operational safety in complex environments.
Data communication with other equipment is handled via an RS-485 interface using the Modbus-RTU protocol, while 2G, 3G, and 4G mobile networks facilitate communication with the control system. The unit allows flexible configuration either remotely through cellular networks or manually on-site, offering adaptability for various installation scenarios. The Luminance Sensor is powered by standard AC mains with a voltage range of 100–240 V, consuming a maximum of 5 W, and is protected by a 0.1 A mains fuse for added safety.
Mechanically, the device is housed in a die-cast waterproof metal casing with a thermo cover, providing protection against environmental factors. Its dimensions are 350 mm in depth, 107 mm in height, and 118 mm in width, with a total mass of 1.8 kg. The unit is designed for vertical surface mounting, including walls, supports, or bars, and offers IP66-rated protection against dust and moisture. Operating temperatures range from -40 to +70°C, with storage tolerances from -50 to +80°C, and it can function reliably in relative humidity up to 100 percent. The device is CE compliant, RoHS certified, and comes with a 36-month warranty, reflecting its adherence to international quality standards.
The Luminance Sensor features an embedded 1 to 1.3 Mpx camera, offering a 30° viewing angle and snapshooting intervals of 5 or 30 seconds. Night mode is supported in the 5 Mpx camera configuration, while the luminance meter is integrated in the 1.3 Mpx version. The device includes automatic heating in the thermo cover to maintain operational performance in cold conditions, and it contains a built-in power supply and 2G/3G/4G modem for seamless data transmission. Electrical and optical connections are made via screw terminals or SAC 5P connectors, while wireless communication is supported over a single channel.
Overall, the Luminance Sensor combines advanced optical monitoring, environmental durability, and flexible communication options to provide a reliable solution for tunnel safety, surveillance, and real-time light monitoring, making it suitable for demanding infrastructure and industrial applications.
