The EM26AQS is a multifunctional gas sensor evaluation module with integrated signal processing software required for the use of TGS 26 series semiconductor type air quality sensors in air quality control equipment, such as electronic air purifiers and ventilation systems.
The module facilitates the evaluation of TGS 26 series air quality sensors before developing gas sensor applications.

This PC application software offers many
useful features and functions, including;

• Real-time graphic display of output data from the module
• Measurement data save in CSV format
• Simultaneous measurement of temperature and humidity by the module’s built-in sensors for reference purposes
• Control of the interval of saving measured data in CSV format on a PC
• Reset button^※1 on a PC monitor to reset the EM26AQS module
• Parameter setting^※2 management

※1 The Reset function is to reset the air quality level output (VAQL) to 1V, with the current ambient air quality being considered clean, regardless of the actual air quality.

※2 Gas sensors can be evaluated under test conditions suitable for their intended use by adjusting the parameter setting for threshold levels of air quality levels and their determining timing.

※3 For details about the PC application software, please refer to the instruction manual.

Start evaluating air quality sensors quickly and reduce the overall product development time.

When using a semiconductor type gas sensor in an air purifier, for example, it is required to study a complicated dynamic benchmark renewal algorithm and develop signal processing software to analyze raw gas sensor responses. The integrated signal processing software based on a proprietary benchmark renewal algorithm for determining the air quality level from raw gas sensor responses allows for a quick and easy start to evaluation of air quality sensors.

renewal algorithm, click here.

There are various possible sources of odorous substances that may cause poor indoor air quality.Examples of odorous substances include cooking fumes, food odor, garbage can smell, cigarette smoke, VOCs from building materials, and odor from house cleaning products such as detergents, air refreshers, or disinfectants.Depending on the intended application and the major odorous substances, a suitable sensor model from our selection of air quality sensors can be chosen to test using the EM26AQS.

The combination of Figaro air quality gas sensors with signal processing software will greatly expand the scope of sensor applications for indoor air quality control equipment.
