Wireless ambient sensor of indirect CO2 and volatile organic compounds

Considering that people spend up to 90% of their time indoors, the presence of gaseous pollutants, particularly Volatile Organic Compounds (VOCs), is significantly higher compared to open spaces. In high-density environments such as offices, schools, hospitals, and other public premises, especially in modern buildings characterized by poor air exchange, there is an increase in the concentration of carbon dioxide (CO2) produced by human activity. 

These negative indoor environmental conditions can significantly impact people's well-being, contributing to health problems, decreased concentration, and reduced productivity

The KET-AIR-200 device uses an indirect method of measuring CO2 based on a MOX technology sensor, which estimates the amount of carbon dioxide by detecting the hydrogen concentration. Combined with a sensor dedicated to measuring Volatile Organic Compounds (VOCs), the KET-AIR-200 allows for the implementation of effective measures to increase and improve ventilation efficiency and air purification, creating healthier and more comfortable indoor environments. 

The KET-AIR-200 also integrates high-precision sensors for measuring Temperature, Relative Humidity, and Ambient Light, providing comprehensive environmental monitoring. 

Thanks to the high sensitivity of its amplified radio module, the device reaches distances of over 600 meters in open air, ensuring a reliable connection with other products in the X-Monitor network, leveraging the benefits of IEEE 802.15.4 wireless technology for efficient and flexible communication. 

The KET-AIR-200.DY version is equipped with a zero-power e-ink display that provides users with detailed information on the level of thermal comfort present in the environment, ensuring optimal and continuous reading of the detected parameters with minimal energy consumption

The KET-AIR-200.TS version allows the user to set the desired comfort level, further personalizing the indoor environment. 

Designed for easy integration into building management and energy management systems (BMS / BEMS), the device offers a simple and remotely manageable user interface, facilitating the monitoring and control of air quality and environmental parameters. Designed for professional use, it supports remote or local firmware updates during maintenance operations. For applications in public environments, it includes keypad lock and limitation of active functions, ensuring safe and controlled use.
