With the improvement of living standards, people are paying more and more attention to the air quality of their environment. Similarly, the internal environmental air quality of cars is increasingly becoming a focus for car owners and passengers. In-vehicle environment monitors can be used to monitor the car interior environment. When in-vehicle air pollution is serious, the product will provide timely reminders or voice alarms and start protective measures when necessary to ensure the health and safety of the occupants.

In-vehicle air monitors have the function of monitoring air quality parameters such as PM2.5, temperature, humidity, and formaldehyde. These monitors have built-in PM2.5 sensors, temperature and humidity sensors, formaldehyde sensors, and CO2 sensors. Through a microcontroller and collection system, they can monitor the current air quality status in real-time and cyclically display air quality indicators.

The Luftmy HPD05 infrared dust PM2.5 concentration sensor module uses the optical scattering principle to detect the concentration of dust in the air. The sensor has a built-in infrared light-emitting diode and a high-sensitivity photoelectric receiving sensor. This infrared sensor module is suitable for air purifiers, vehicle-mounted purification equipment, and air quality testing instruments.

As cars increasingly enter households, they bring convenience but also the invisible killer of in-vehicle air pollution. Particularly with the continuous expansion of China's industrial scale, current PM2.5 values in major cities remain high, causing serious pollution to the car interior environment. The quality of the in-vehicle air environment has increasingly attracted the attention of car owners. Vehicle-mounted PM2.5 monitors are mainly used for monitoring PM2.5 in the car, while also monitoring other air quality parameters like temperature, humidity, and formaldehyde. When in-vehicle air pollution is serious and endangers lives, the product will start protective measures in time to ensure the health and safety of the people inside.

The laser dust sensor module LD15, developed and produced by the particle concentration sensor manufacturer Luftmy, is a high-precision particulate matter concentration sensor based on the laser Mie scattering theory. It can continuously collect and calculate the concentration distribution of particulate matter in the air per unit volume and output it in the form of a universal digital interface. This laser sensor module can be embedded into various instruments or environmental improvement equipment related to suspended particulate matter concentration, such as air conditioners with purification functions, air purifiers, and vehicle-mounted purification equipment, providing timely and accurate concentration data.
