An Autonomous City-Wide Light Pollution Measurement Network System Using LoRa Wireless Communication

Abstract

Light pollution is an ongoing problem for city populations. Large numbers of light sources at night negatively affect humans’ day–night cycle. It is important to measure the amount of light pollution in order to effectively ascertain the amount of light pollution in the city area and effectively reduce it where possible and necessary. In order to perform this task, a prototype wireless sensor network for automated, long-term measurement of light pollution was developed for the Torun (Poland) city area. The sensors use LoRa wireless technology to collect sensor data from an urban area by way of networked gateways. The article investigates the sensor module architecture and design challenges as well as network architecture. Example results of light pollution measurements are presented, which were obtained from the prototype network.

Real-time monitoring and data acquisition using LoRa for a remote solar powered oil well

“…The assessment of LoRa's communication performance involved systematic adjustments to parameters such as transmit power, communication rate, payload length, and the placement of wireless modules. Erwinski et al [23], a self-sustaining distributed light measurement system is introduced, designed for prolonged monitoring of light pollution in urban settings. This system primarily consists of self-sustaining measurement devices equipped with LoRa wireless communication capabilities, enabling extensive coverage in diverse environments.…”

Light pollution measurement and strategy modelling based on multidimensional data

“…From the point of view of how to measure light pollution, many scholars have proposed their own measurements. For the automatic, longterm assessment of light pollution, Erwinski et al [1] have created a prototype wireless sensor network. They provide samples of the light pollution data they were able to gather from the prototype network.…”
