Data was taken using a data logging sky quality metre. The field and species survey was downloaded from the national biodiversity data cortex.
ABSTRACT: Environmental light pollution, brought on by excessive artificial illumination at night, has grown to be a serious problem that has an impact on both the environment and human health. Scientists and researchers are constantly looking for reasonable remedies to lessen the effects of this issue. An updated survey technology will be used to undertake light pollution surveys in controlled and test situations. These surveys can assist in gathering quantitative information on the level of light pollution in various environments, which can help guide mitigation initiatives. By carrying out these studies, the project can offer insightful information on how artificial lighting affects the environment and assist in identifying practical ways to reduce ecological light pollution.

1. INTRODUCTION:The development of technology is a double edged sword. Technology makes our life easier but there is always a price to pay when the use of technology is uncontrolled. Light pollution is one such instance where the overuse of artificial lights have caused ecological impacts on the biodiversity of the well lit area during the night time. Ecological light pollution impacts the diurnal cycle of a majority of the biome that do follow the cycle and also is a major factor in the decline of various insect populations and also the oceanic life such as sea turtles.[1] while there is a field of ongoing research on light pollution, a survey method is also a research material. A comparison is done between the existing survey methods in various countries and a tool will be developed to best fit our area of survey of the pollution and a systematic survey will be conducted using our modified device.

2. LITERATURE REVIEW:I. The survey done in rural Ireland[6] used satellite measurement of night time light monitoring methods. To overcome some limitations, calibrated data has been used to produce a series of annual average georeferenced cloud free image coverage. Ground based measurements used zenithal light measurement
