An air quality monitor is a smart device designed to detect and display real-time data about indoor or outdoor air conditions. It measures pollutants like PM2.5, PM10, carbon dioxide (CO2), volatile organic compounds (VOCs), and sometimes humidity and temperature. Ideal for homes, offices, or nurseries, it helps ensure a safe breathing environment. Many models come with digital displays or connect to apps for remote monitoring. This device alerts users when air quality drops, promoting timely ventilation or purification. It’s especially useful for those with allergies, asthma, or respiratory conditions. Compact and easy to use. A valuable tool for healthier living.
