What is the principle of interpretation of the portable odor detector?

Author:QINSUN Released in:2023-06 Click:117

The wearable smell detector is an artificial olfactory instrument composed of an array of electrochemical sensors, mimicking the human olfactory system and organically combining sensing technology with pattern recognition technology and computer technology;

It can quickly and identify the concentration of various gases in a disordered environment of several mixed gases, perform quantitative analysis and give an alarm in time.

It is an artificial olfactory instrument composed of networks of electrochemical sensors , imitating human beings. The olfactory system organically combines sensing technology with pattern recognition technology and computer technology.

The portable odor detection system is a new type of intelligent sensory analysis system developed for the detection of volatile components afterthe electronic language system.

The electronic tongue detection target is mainly the solution, and the electronic nose ction detection target is mainly the volatile aromatic substances.

When one or more aromatic substances pass through the electronic nose, the aromatic substances can be detected by the sensor and extracted by a special intelligent pattern recognition algorithm.

By using different olfactory fingerprint information of different aromatic substances, different gas samples can be distinguished and identified.

The portable odor detector has the ability to expand the detectable gas by identifying the gas surface spectrum, so as to realize the function of identifying a variety of gases .

And identify different gases and measure the concentration of the measured gas at the same time.

The lower measurement limitre can reach ppm level. Accuracy is less than 5%. The intelligent toxic gas detection instrument composed of an array of electrochemical sensors organically combines detection technology, pattern recognition technology, computer science technology, etc., and can reliably detect and measure a variety of gases different.

At present, wearable smell detector technology research mainly focuses on sensor preparation, pattern recognition algorithm and application, and rarely involves research into the structure of the electronic nasal air chamber.

Inspired by the principle of biological olfaction, the electronic nose is a sensing instrument that mimics the mammalian olfactory system in structure and function.

Compared with ordinary detectors, it has the following outstanding advantages and features:ts:

1. Rapid, qualitative, quantitative, portable or real-time monitoring

2. Strong anti-interference ability, accurate detection, no easy to be affected by various gases and cause false alarms

3. Can automatically distinguish and measure a variety of different gases

4. It has a unique intelligent learning function, which can continuously improve its ability to detect kinds of gas

5. Real-time automatic monitoring, and can be used with Joint Alarm NetworkOr the center Upper control panel is connected to realize long-distance early warning, long-distance communication and remote control.
