Abstract

The purpose of this thesis is to analyse data reliability collected by do-it-yourself indoor air quality monitoring solution and give a comparison overview with a commercial off-the-shelf product called “Smart Home Weather Station” by Netamo. As a result of this thesis a prototype was constructed that was able to collect and store real time readings of temperature, humidity, CO2 and air pressure. The prototype used ESP32 microcontroller together with 2 additional sensors SCD30 and BMP280. All data was stored in a cloud-based database using MQTT bridge for connection. Measured readings resembled reference data gathered by Netamo and despite minor offsets in the data the prototype was concluded reliable
