On the Architecture of a Low-Cost Meteorological Station Based on the Internet of Things (IoT): Preliminary Results

Key Points

The portable meteorological station provides similar results to a commercial counterpart, enabling real-time data access.
Data collection over 29 days includes temperature, humidity, and atmospheric pressure metrics, sampled every 10 seconds.
The ESP8266 microcontroller manages data collection, and the system can store information on a micro-SD device.
Further enhancements will expand measurement capabilities and deploy additional stations across different regions.

Abstract

This study presents the development, construction, and implementation of a portable meteorological station. An ESP8266 microcontroller was used as the control system. Temperature, humidity, and atmospheric pressure were measured. The UV index, thermal sensation, dew point, altitude above sea level, and air density were measured indirectly. An interface was created to retrieve the data in real time via the internet. The information can also be stored on a micro-SD memory device. The first results were collected over a period of 29 days. The data is sampled every 10 s. The data was compared with that of a commercial meteorological station and yielded similar results. The design of the meteorological station will be further improved by adding new measurement variables and installing a few portable stations in different regions of the state.
