Light intensity meter

Light sensor devices are used to measure the light intensity and the brightness of the tunnel entrance. These sensors usually operate on the photosensor principle, which is actually capable of converting light radiation into an electrical signal. The TLS1 series light intensity meter is a sensor used to measure the average brightness of the tunnel entrance and its surroundings. This sensor has a silicon photocell that, due to the built-in filters, gives a response similar to the function of the human eye. This detector has a fast response to changes in light levels, linearly proportional to the measurement range. If you want to measure the brightness of the tunnel entrance, you can install a light sensor at the tunnel entrance point. This light sensor measures the ambient light intensity and is sent to the relevant control devices or systems via an output electrical signal. This system can be used as an intelligent tunnel lighting control system, so that based on the intensity of incoming light, the lighting levels inside the tunnel are adjusted, improving the safety and comfort of passers-by. General features Accurate measurement of light intensity Limited viewing angle (02 degrees) Equipped with standard outputs No effect of ambient sound and traffic reflection
