Using Adaptive Transmit Power in Wireless Indoor Air Quality Monitoring
Andrei Rusu, Petru Dobra · 2019
In the past few years, the general interest in connected home, smart devices and appliances has risen significantly. New concepts like the Internet of Things have inspired new applications and research areas for sensors and gathering data from them. One important application that makes use of these new technologies is monitoring indoor air quality, which according to Directive 2010/31/EU of the European Parliament and of the Council, can “reduce mortality, morbidity, and health care costs”. In this context, this paper proposes a solution for wireless monitoring of indoor air quality parameters including temperature, humidity, CO2 and TVOC levels using a low-power ARM Cortex-M microcontroller, an IEEE 802.15.4 sub-GHz transceiver and temperature, humidity and gas sensors and observing the changes in overall power consumption by implementing an adaptive transmit power technique.
