Portable Weather Station for Night Sky Observers

Light pollution is one of many problems in world. For solve that problem, we need to know how much is night sky polluted with artificial light. Many students with teachers in world try to measure light pollution with expensive sensors. I decided to change my portable luxmeter (for more check previous instructables project Portable Luxmeter ) to weather station with TSL2591 sensor. This sensor is sensitive enough for measure night pollution. Also, I add HTU21D for temperature and humidity measure.”
