INDOOR IQA SOLUTION WITH FBAR TECHNOLOGY AND STONE LCD

 

Indoor air pollution with VOC is becoming the major health issue of humankind. Smart house systems and VOC sensors will give us a solution to monitor the indoor IAQ.

With the development of the model industrial, air pollution becomes a major issue for humankind's health.

We used to focus on the outdoor air problem around 10 years ago. Particle matter (PM) is a frequently heard word in the news and reports. People used to think that stay at home and close the window will isolate them from the pollution. But indoor air pollution also becomes a point which we can’t ignore right now. Volatile organic compounds (VOCs) have been proofed to be related to many kinds of major decease, such as formaldehyde and leukemia.

 

According to WHO, the combine effects of outdoor and indoor air pollution cased about 7 million death per year

 

The organic compound material and the indoor air-quality control become more and more important these days. With the development of the smart house device and VOC sensor, indoor IQA equipment (https://www.epa.gov/indoor-air-quality-iaq)becomes more and more popular. It used to be a very expensive and professional device, which could only be operated by a specific operator. Nowadays it becomes simple and affordable.

 

STONE TFT LCD plays an important role in the smart house system. The intelligent TFT LCD module allows the manufacturer to design a simple and easy GUI system, which could display the icons and numbers, show the IQA/temperature/humidity and different kinds of parameters, and easily communicate with the main controller via the UART interface.

The VOC sensors have been also developed. The SOREX Sensors, UK will release a small-sized, low power consumption sensors which could detect 5 different kinds of VOC including the formaldehyde.

The combination of these 2 kind of device could give us a user friendly, affordable home use indoor IQA monitor. And the possibility of smart house system and intelligent equipment will help us to have a better and healthy life in the future.
