IoT (INTERNET OF THINGS) APPLICATION TO CREATE AN OPEN-SOURCE PROTOTYPE FOR ENVIRONMENTAL MONITORING: CASE STUDY ON THE BURANHÉM RIVER
Internet of things, NodeMCU, Arduino, Environmental Monitoring
The technologies used for environmental monitoring shows a great advance in the search for a better understanding of the environment and the climate change phenomena and other ills caused by anthropic activities. A promising low cost alternative is the use of so-called IoT - Internet of things. Recent data estimates that the approximate amount of IoT devices connected to the internet by 2025 will reach 75 billion. Within devices known as IoT the Arduino prototyping platform is the most widespread through its simplicity, and as an open-hardware has allowed other end-use devices to be developed, including the NodeMCU based on the ESP8266 microcontroller, chipset. already supporting WiFI (IEEE 802.11) networks. The objective of this paper was to develop a low cost IoT-based wireless monitoring system, connected to a wifi network, powered by solar panels in an open-source environmental monitoring prototype. called by the author of ecoIOT, in the period from May to September 2019 as a case study real-time monitoring, sent to the internet the environmental parameters (temperature, light intensity, atmospheric pressure, relative humidity) and water surface (temperature and pH) in the Buranhém river estuary in Porto Seguro, southern Bahia.
