Auto-Air works together with a PMS7003 module, a sensor for detecting pm2.5 and pm10. The air-cleaner, honeywell PAC1101 with a touchable control panel, will be turned on automatically when the pm2.5 >= 120 ug/m3, and turned off automatically when the pm2.5 < 100 ug/m3. You also can use your mobile phone to remotely turn the air-cleaner on or off.
