Evaluation of low cost Environmental Monitoring Sensors.

Abstract

Low-cost environmental monitoring devices are an elegant solution to increasing wider adoption of environmental monitoring devices in many fields of applications. This project proposes a collection and analysis of data from a selection of these sensors and compare it amongst the sensors and with existing expensive industry standard devices to assess their reliability and accuracy. The data was collected with a designed evaluation board and compared using modern data analysis methods. Clear deviations in performance and consistency amongst the sensors were observed at different conditions.
