Many people work outdoors all day, but they must still be careful to keep away from viruses even after they go home. Germs spreading through the air is one of the possible transmission routes for these viruses, so how to prevent group infection within a building is a very important issue. Many leading brands have started releasing air purifiers that can eliminate bacteria and viruses. 

Nuvoton provides microcontrollers suitable for air purifiers; features of the solutions include:

• It can be controlled remotely so that users can get great air quality as soon as they step through the door of their homes.
• Smart monitoring system: Detects temperature, humidity, PM2.5, air quality, and filter life.
• Air quality sensor, temperature and humidity sensors, and PM2.5 sensor. 

Introduction to the M031 microcontroller

• M031 provides high flexibility and is suitable for different high-end air purifiers.
• Provides 2 MSPS ADC that can quickly detect the quality of the air.
• Provides I²C that can be used to connect temperature and humidity sensors.
• Provides UART and PWM that allows flexible connection of a PM2.5 sensor.
