Volatile organic compounds sensor module reacts to various substances
This method not only ensures a very quick response to changes, but also enables faster recovery times. In addition, the sensor, which reacts to different volatile substances such as carbon monoxide (CO), toluene and ethanol, features an almost twice as high resolution, especially at low concentration levels, compared to the conventional resistive measurement method.
Thanks to the Digital Sampling Process (DSP), specially developed by Unitronic for the USM-VOC, the module is able to use the very short response times and measurement cycles of the gas sensor without any limitations and at the same time achieve a high level of accuracy in the measurement.
Not only does the USM-VOC react up to 20% quicker to the release of harmful gases compared with conventional resistive gas sensors, but also the true gas concentration in the air can be detected significantly earlier. For example, with the reference gas toluene 30 ppb (parts per billion) are already enough for an exact detection.
The module measures 30x30mm and operates from a 5V supply voltage. It can be easily integrated into customers’ own circuits and applications thanks to an analog and a digital output (UART).
