• Indoor Air Quality Management

Air quality monitor AM7000 is OEM based intelligent desktop indoor air quality monitor with a fashionable and compact design. It could integrate a high-quality air quality sensor module, which can monitor indoor air quality and output real-time data of PM1.0, PM2.5, PM10, CO2, HCHO, VOC, RH&T, etc. With the improvement of people’s living standards, more and more people begin to pay attention to the air quality of their living environment. Based on self-developed gas sensors, Cubic has developed a variety of air quality sensor that can detect PM2.5, CO2, formaldehyde, VOC, temperature and humidity in the air.

We have successfully solved the problems of air duct design, power consumption and temperature rise in the integrated design process of the sensor. Structural design: The air quality detector is a measurement instrument, so we need to ensure detection accuracy. But the laser dust sensor is installed inside the air quality detector, so the external structure and the installed dust-proof gauze will affect the sampling flow rate of the laser dust sensor, result in lower measurement accuracy of the sensor. We find the most suitable structural design scheme with the least impact on the sensor by fluid simulation and verification, and combine the secondary calibration technology to ensure the measurement accuracy of the laser dust sensor.

Power consumption problem: In order to meet the portability of the air quality detector, it needs to use battery power and ensure its battery life. When multiple sensors work at the same time, the battery power consumption will be too fast, bringing a bad user experience.
