Cloud-based smart device for environment monitoring

Due to the advancement in technology and increase in economic growth, environmental pollution has become rampant throughout metropolitan cities. Thus, the purpose of this research is based on designing a low-cost, cloud-based smart device named Cloud-based Environment Monitoring Smart Device (CEMSD) that monitors different environmental parameters such as air quality, noise, temperature and humidity. To build the CEMSD, the Raspberry Pi 3 (RPi 3) Model B is used and thus a microprocessor along with DHT11 temperature-humidity sensor, Grove-Loudness sensor, Shinyei PPD42NS particle matter (PM) Grove dust sensor, COZIR Wide Range 100% Carbon Dioxide (CO2) sensor and the MQ131 Ozone (O3) Gas sensor. The CEMSD collects and sends data from targeted measurement locations through wireless network or cellular network to a cloud server, where data is stored, processed and can be accessed using a computer or any smart device. The utilization of social media is also involved once the CEMSD environmental index exceeds the threshold. Subscribed user receives notification from social media such as Facebook or twitter to avoid the exposure to severe environmental condition. The CEMSD can be integrated into the making of Smart Cities which would help reduce level of pollution, save energy and provide an overall living environment enhancement.
