Abstract

Pollen Neutralization System aims to maintain desired indoor temperature, humidity and pollen density, based on the hypothesis that certain temperature and humidity help reduce pollen density. The system displays real-time values of temperature and humidity sensor (DHT22), dust sensor (DSM501A), and predicts the trends of temperature and humidity. Fuzzy control strategy was used to eliminate overshoot of temperature control. Relay ports were reserved to control Heating Ventilation and Air Conditioning (HVAC), Humidifier, and High Efficiency Particle Arrestance Filter (HEPA). Moreover, a previously published experiment by Barnes et al. was referred to testify the relationship between temperature, humidity and pollen density. Another self-designed experiment was compared and analyzed, where pollen density is surrogated by dust ratio. Those two experiments demonstrate that temperature and humidity have minimal influence on pollen density and dust ratio.
