| Abstract |
The purpose of the study is to develop an IoT sensor module for environmental measurement that can compare indoor and outdoor contamination. Low-cost and high-performance indoor environmental devices have been developed for easy access by researchers. The results as follows: The products used the Aduino Uno R3 with outstanding scalability and affordability. Performance verification shows the same trend of Fine dust concentration, Temperature and humidity error rate were 4.08% and 4.96% respectively, Air flow error rate is 4.58%. Therefore, the sensor modules developed in this study can be applied indoor the building for environmental measurement and are easily accessible to other researchers. |
