What is meant by e-nose?
An electronic nose (e-nose) is a device that identifies the specific components of an odor and analyzes its chemical makeup to identify it. An electronic nose consists of a mechanism for chemical detection, such as an array of electronic sensors, and a mechanism for pattern recognition, such as a neural network.
How much is the e-nose?
This design allows the research community to have a very low cost electronic nose (around $US 200) that can be configured and used with a very basic knowledge of electronics.
Which sensor is used in e-nose?
Table 3.
| Sensor type | Sensitive material |
|---|---|
| Fluorescence sensors | Fluorescence-sensitive detector |
| Infrared sensors | IR-sensitive detector |
| Metal oxides semi-conducting (MOS, Taguchi) | doped semi-conducting metal oxides (SnO2, GaO) |
| Optical sensors | photodiode, light-sensitive |
How many sensors are in the nose?
They can have up to 40 sensors, each calibrated for a different chemical specificity, which, when combined provides a measurement pattern. The electronic nose relies on pattern recognition and therefore cannot identify unknown (or unexpected) compounds.
Can machines detect smell?
Machine olfaction is the automated simulation of the sense of smell. An emerging application in modern engineering, it involves the use of robots or other automated systems to analyze air-borne chemicals. Such an apparatus is often called an electronic nose or e-nose.
How do electronic noses work?
An electronic nose works in a similar fashion. An array of chemical sensors is used to mimic the range of protein receptors in the human nose. Each of these sensors is made to respond differently to different odors. The signals from these sensors are connected via electronics to a microprocessor or computer.
Is there a smell sensor?
Generally, odor sensors are designed to detect some specific odor in an electrical appliance such as an air purifier or a breathylzer….6.4. 1 Outline of olfactory recognition and classification.
| Sensor number | Materials of the membrane |
|---|---|
| Sensor 8 | No membrane |
