tunnel color temperature sensor
The tunnel color temperature sensor is an intelligent sensing device designed to measure the color temperature (in Kelvin) of light sources within tunnels. It is primarily used in tunnel lighting control systems to ensure visual comfort and safety at tunnel entrances, exits, and throughout the interior. Its features include high-precision measurement, fast response times, strong resistance to interference, adaptability to changes in both bright and dim lighting conditions, and support for long-term stable operation. It is widely used in highway tunnels, railway tunnels, urban underpasses, and intelligent traffic lighting systems to enable on-demand dimming, energy-saving control, and enhanced traffic safety.

บทนำ
The tunnel color temperature sensor is a device specifically designed to measure the color temperature (expressed in kelvins, K) of tunnel lighting sources. It monitors changes in color temperature in real time at the tunnel entrance, in transition zones, and within the tunnel, and transmits this data to the lighting control system. This enables automatic lighting adjustment, ensuring drivers’ visual adaptation and driving safety while also addressing energy-saving and intelligent management requirements.
Structure color temperature sensor
- Optical Filter: Separates incident light into specific wavelength bands (typically RGB or multi-channel filtering) to mimic the human eye’s response to different colors, thereby improving the accuracy and stability of color temperature calculations.
- Photodiode / Sensor Element: The core light-sensitive component that converts received light signals into electrical signals.
- Signal Conditioning Circuit: Amplifies, filters, and reduces noise in weak electrical signals.
- A/D Converter (Analog-to-Digital Converter): Converts analog electrical signals into digital signals for subsequent processing and transmission.
- Microcontroller Unit (MCU): Performs calculations on multi-channel data, converts it into color temperature values (CCT) using algorithms, and performs data calibration and compensation.
- Temperature Compensation Module: Calculates the color temperature value and outputs the data.
- Protective Housing: A waterproof and dustproof enclosure designed for outdoor or tunnel environments.
- Output Interface: Such as RS485 or MODBUS, used for data transmission.
