This project aims to develop a low-cost device to monitor the quality of air, simultaneously measuring NH3, CO2, NO2, temperature, pressure and geographic coordinates, and sending this data to the cloud. Using the ESP8266 Node MCU WiFi module for its connectivity and versatility, the MICS-6814 sensor to detect gases, and the BME680 for meteorological variables, complemented by the NEO-6M V2 GPS for geolocation, this prototype allows real-time and cost-effective monitoring of pollution urban. The results indicate that the device was able to capture significant variations in pollutant concentrations in areas with different levels of traffic, demonstrating its effectiveness in identifying areas of potential risk to public health. This data is crucial for implementing more effective health and urban planning policies, emphasizing the importance of technological innovations to face environmental challenges and improve the quality of life in cities.
