Surveillance of environment using node Mcu based on Iot

Abstract

This paper proposes a way to build a cost-effective environmental monitoring system using Node MCU. The surroundings in which human beings, animals or plants live is called Environment. Detection of environment parameters like temperature, humidity, carbon dioxide and others, these factors play a significant role, as it is directly linked to health conditions of people in the environment. For the design of this hardware we use an ESP8266 Wi-Fi chip enabled microcontroller Node MCU, which is the hardware used to measure the temperature, humidity, pulse rate of the human beings and air pollutants like co2. These parameters are monitored continuously around the user’s environment and transfers the Data to Things Board Server, which is one of the best platforms to display and maintain the data by ESP8266 WIFI module from Node MCU.
