The CT902 is an optical sensor, which is a type of ambient light, IR, and UV sensor. The sensor is used in a wide variety of industrial, commercial, and residential applications, to detect changes in levels of light. It can be used to detect whether an area is being illuminated or not, or whether an area is being over-illuminated; it can also be used to monitor changes in levels of light to ensure that a given area remains within a certain range of brightness.

The CT902 is composed of an infrared (IR) diode sensing element, a light-adjustable memory, and a negative temperature co-efficient resistor. The sensing element receives incident light and converts it to an electrical signal. The light-adjustable memory works as a reference to which the signal from the sensing element is compared. Finally, the negative temperature co-efficient resistor stores the previous record of light intensity for comparison with the present measurement. This integrated circuit is able to accurately measure light levels in both visible and infrared spectrums.

The CT902 is used in a variety of applications, such as in automotive lighting, industrial lighting, commercial lighting, and even for residential lighting. It can be used to detect whether an area is brightly lit, or whether an area is in darkness; it can also be used to monitor changes in light levels to ensure that a given area is not over illuminated. The CT902 can be set up to trigger alarms or other actions in the event that light levels exceed certain thresholds. Additionally, it can be used to automate lighting based on changes in ambient light levels.

The CT902 is a low power, high accuracy light sensor that can measure light levels from 0.1-20,000 lux (around 20,000 lumens). The sensor has a response time of less than 20 milliseconds, and can be configured to measure average, peak, or even low light intensities. The CT902 is extremely durable and reliable, with a minimum lifespan of 10 years, and a maximum lifespan of 25 years. Moreover, it is very cost effective, as it requires very little power to operate, and occupies very little space.

The CT902 ambient light, IR, and UV sensor is an extremely useful tool that can be used in a wide variety of applications. It is able to accurately measure light levels in both visible and infrared spectrums, and is durable and reliable. Additionally, it is low power, cost effective, and occupies very little space. For these reasons, the CT902 makes a great ambient light, IR, and UV sensor for commercial, residential, and industrial lighting applications.
