| Abstract | Home environmental monitoring, such as air quality, temperature, humidity, and carbon monoxide concentration, gets more and more attention today. This study develops an internet of environmental monitoring system based on 32-bit ARM Cortex-M0 microcontroller¡]LPC1115¡^, which collects the data of environmental sensor and connects the TCP / IP network via Wi-Fi module. The developed internet of environmental monitoring system uploads monitor-ing data to server via Wi-Fi module controlled by LPC1115 through UART inter-face, the remote devices can access the environmental data without limits. The LPC1115 controls OLED module as well through I2C interface to display the monitoring data real time. The data is gathered by the LPC1115 through miscella-neous sensors, including temperature sensors, humidity sensors, gas sensors and dust sensor. This study performs an internet of environmental monitoring system by exploiting an inexpensive M0 microcontroller driving five peripheral devices simultaneously. Because the Wi-Fi module and the dust sensors of the proposed system both utilize UART interface to communicate LPC1115 simultaneously which with only one UART, this study develops a strategy of simulating UART transport by GPIO pins of LPC1115. |
