The Application Of Modular Sensor In Environment Detection System And The Internet Of Things
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 11
Abstract
The application of modular sensor in environment detection system and the Internet of Things developed in this thesis allowed user to select required modular sensor. For this research, a variety of sensors was developed, including DHT11 of a single bus transmission, BMP180 with IIC transmission interface, air quality sensor and UV index sensor with analog output, that various transmission modes were converted into UART transmission interface through MCU of each sensor. Once the exclusive interface of WIFI module was plugged in, the WIFI terminal would receive the data transmitted from the sensor end to be decoded and categorized by the MCU at the WIFI terminal, before these data from different sensors were released to MQTT and uploaded to the cloud storage, which could be observed via any network, as well as monitoring the current status with the remote mobile APP. User can real-time monitor and store data on the cloud with one single step to reduce experiment cost and program development.
