ASUKA Announces CO2 Monitoring System leveraging Exosite and Infineon

ASUKA Autotronics & Smart Sensing Inc, a prominent manufacturer of IoT (Internet of Things) edge device, announced last month (December, 2022) that it has cooperated with Infineon and Exosite to launch an "Indoor CO₂ Monitoring Cloud System", which will be applicable to smart buildings, industrial workplace monitoring, smart agriculture, and other related use cases. It helps enterprises to swiftly establish an indoor air quality monitoring system that meets the Environmental Protection Administration (EPA) regulations, and add value to the system integrators’ IoT service.

High Indoor Carbon Dioxide Level Health Hazard

Carbon dioxide (CO₂) is a colorless and odorless gas emitted by human activities. It is the most critical indicator of indoor air quality. The CO₂ level of outdoor fresh air is around 400 ppm, while the CO₂ level of a well-ventilated office is about 600-800 ppm. If people are exposed to high CO₂ levels (more than 1000 ppm) for a period of time, the CO₂ itself can cause headache, dizziness, nausea and other symptoms.

Governments around the world are developing ventilation guidelines and regulations that should maintain a comfortable environment (such as schools, hospitals, shopping malls, working facilities, etc.) for most occupants. Taiwan EPA framed the "Indoor Air Quality Management Act '' that regulates certain premises owners to measure, announce, and keep records of CO₂ concentration for inspection every two years. 

ASUKA leverages Infineon and Exosite 

ASUKA KP-200W is a high-sensitive, system-level CO₂ sensing module by utilizing Infineon’s PAS technology CO₂ sensing IC, microcontrollers, and WiFi. It is capable of measuring the indoor air quality every minute and uploading the sensor data via WiFi to Exosite’s ExoSense®, a condition monitoring cloud application that provides visualizations and operational insights. The IoT data is securely stored in Exosite’s IoT software platform and can also be accessed by ASUKA's mobile APP.

"We have made the two important things, CO₂ sensing and cloud data processing, easier," said Dr. Ron Hu, President of ASUKA Autotronics. "Because ASUKA’s system-level CO₂ sensing module KP-201W has been successfully integrated with Exosite ExoSense® and other well-known public cloud platforms, its sensing data can be easily and quickly sent to the cloud without editing any code, achieving a painless plug-n-play IoT system.” Dr. Hu added.

The Next Step

President Ron Hu also revealed that the next product will be a system-level module based on Infineon's CO2 sensing IC and 60GHz mmWave radar sensor. The mmWave radar can capture subtle movement of people and vehicles. It can be used in smart homes, smart buildings, security monitoring etc. Thanks to its low power consumption, mmWave radar can be used to control electronic appliances to achieve the goal of energy saving and environmental sustainability. The new product will be also compatible with Exosite ExoSense® condition monitoring cloud application.
