Affected by haze, more and more fresh air purification products have entered thousands of households. Most of these products filter the air through filters to remove harmful gases in the air.

    The main function of the air purifier is to purify the original dirty air in the room, and it cannot introduce fresh air rich in oxygen. The fresh air fan is known as the "mobile oxygen bar" and is currently a very popular solution for indoor air pollution.

    The fresh air system is a group of independent air treatment systems composed of air supply and exhaust systems. In simple terms, the fresh air fan can be regarded as the "breathing system" of the house. After installing it, the house can breathe independently, and keep the indoor air healthy and comfortable at all times.

    In the intelligent fresh air system, the real-time detection of air status can be achieved by adding detection sensors (such as dust sensors at the front end of the filter), and the operation of the fresh air fan can be controlled according to the monitoring data. In this way, the changes in indoor air quality can be intuitively seen, and the operation of the fresh air equipment can be reasonably controlled to achieve efficient and energy-saving air purification.

 TZJ06 Laser Dust Sensor

    TZJ06 laser dust sensor is a dust detection sensor that can be used in the intelligent fresh air system. It is a universal, miniaturized laser dust sensor module that uses the Mie scattering principle to detect dust particles in the air.

    In the fresh air system, the dust sensor is a key component for controlling the intelligent operation of the fresh air fan, and its performance parameters determine the operating efficiency of the intelligent fresh air fan. The two dust sensors installed at the front and rear ends of the filter detect the particulate content in the air. The main control chip controls the operation of the axial flow fan according to the detection data of the sensor, so that the air is filtered through the filter, thereby achieving purification.

    In addition, the filtering effect and remaining service life of the filter can be judged according to the detection data of the sensor. At the same time, the fresh air fan can upload the sensor detection data, fan operation status, PTC heating component status and other operating parameters to the cloud server via WiFi, realize mobile phone APP control, and further improve the user experience.

    In addition to dust sensors, smart fresh air fans can also integrate multiple air quality sensors such as formaldehyde, carbon dioxide, TVOC, etc. to monitor a variety of indoor air pollutants, keep the indoor air quality at its best, and improve people's living comfort.
