Development of IoT Based Meteorological Measurement System

Abstract

The atmospheric parameter sensing is pivotal in the forecasting of the weather. The meteorological parameters like temperature, humidity and pressure are measured with the usage of sensors. The DHT11 sensor is employed for measurement of humidity where as the BMP180 sensor is used for the monitoring of temperature and atmospheric pressure. The sensors are interfaced to NodeMCU ESP-32S module. The humidity sensor is interfaced with the single-wire two-way serial protocol and the pressure sensor is interfaced with the I2C protocol. The Arduino IDE is employed for scripting the software of the system. The developed prototype is connected to IoT with the help of inbuilt Wi-Fi module in the NodeMCU EPS-32S. The data collected is portrayed on a web page developed in the IDE. The system is compact and easy to use with its plug and play nature. The prototype can be deployed over various areas such as home automation, industries, healthcare centers.
