Wireless Indoor Air Quality Sensor Platform

This paper deals with design of embedded platform for measuring indoor air quality (temperature, pressure, relative humidity, carbon dioxide concentration, volatile organic compounds concentration). Both hardware and software design is presented. Device is capable of measurement, data transmission to remote server (WiFi/Internet and LoRa network) and has web interface for visualizing results and basic configuration. Sensoric platform is compared with calibrated lab sensor and first real-world deployment is realized.
