PM2.5

Modern smart air purifiers combine HEPA H13/H14 filtration with IoT connectivity, letting you monitor and automate indoor air quality in real time via Home Assistant — from CADR sizing to automatic filter-change alerts.

Build a hyperlocal AQI dashboard combining personal PurpleAir sensor data, Pollution Control Department Air4Thai API, and community sensor networks to map PM2.5 at street level across Bangkok.

Build a sensor fusion system combining SDS011 PM2.5, BME680 TVOC, and SCD40 CO2 readings through a Kalman Filter to compute an accurate Indoor Air Quality Index with automated LINE alerts.

Design ventilation systems to maintain positive indoor pressure, preventing PM2.5 and outdoor pollutants from infiltrating through building envelope gaps during high AQI events.

Design a multi-stage air purification system for Bangkok homes and condos — comparing G4 pre-filter, activated carbon, HEPA H13, UV-C 253.7nm germicidal lamp, and electrostatic precipitator, with IoT pressure sensor monitoring for automatic filter replacement scheduling.

Design HRV and ERV systems for Bangkok condos — comparing HEPA H13 vs H14 filtration media, duct layout, and AQI sensor integration for automated fresh-air ventilation during Bangkok’s high-pollution season.

Install PM2.5 (Sensirion SPS30), CO2 (SCD40), and TVOC (SGP30) sensors in Home Assistant to automate HRV/ERV ventilation and air purifier control — tackling Bangkok AQI and sealed indoor air quality.

SmartInterior integrates intelligent sensors — from motion and air quality to lighting and security systems — for a home that is genuinely comfortable and safe.

HappySmart’s Smart Home technology elevates daily life in Bangkok across every dimension — from waking up to going to sleep — with systems that work as one coordinated ecosystem.
