What is the principle of negative oxygen ion sensor?
Negative oxygen ions in the air are formed by the combination of oxygen molecules in the air with free electrons, with a negative charge and excess electrons, with the reputation of "air vitamin". Air negative oxygen ions have the characteristics of migration far, high activity. Medical research shows that: negative air oxygen ions on the human body has a health care effect. Negative oxygen ions can penetrate the human blood-brain barrier, play its biological effect.

The World Health Organization has also made relevant regulations on the standard concentration of negative oxygen ions for fresh air. The negative oxygen ion sensor can monitor the air negative oxygen ion for forestry, environmental protection, meteorology, tourism units, etc., and provide reliable data for improving the air in rural and urban areas, which is of very great significance to human society.

Negative oxygen ion detector monitoring principle:
According to the different structure of the collector, the mainstream negative oxygen ion sensor can be divided into two types: parallel electric plate type and double cylinder shaft type.

1. Parallel electric plate type negative oxygen ion sensor
Parallel electric plate type negative oxygen ion sensor is currently a more common method of low-end air ion detector. A and B a set of parallel and mutually insulated electrodes, B pole top side of a ring bipolar electrode, air through the lower right corner of the fan inhalation, negative ions in the air hit A/B electrode discharge, charge conduction to the E ring electrode to form self-discharge, discharge signal is recorded, so that the number and size of positive and negative ions in the air can be measured.

This detector is technically more mature, the cost is also relatively low, but vulnerable to the external environment, in addition to this structure's own weaknesses easily lead to electrolysis edge effect, easy to cause airflow turbulence, resulting in large bias detection results.

2. Double cylinder shaft type negative oxygen ion sensor
Double cylinder shaft type negative oxygen ion sensor is currently a mature method of medium and high-end air ion detector. The overall structure consists of three concentric cylinders, the outer cylinder body and the inner shaft for the electrode, air through the cylinder, ions hit the cylinder body with the shaft to generate discharge, discharge signal is recorded, so that the number and size of positive and negative ions in the air can be measured.

What Are the Functions of Negative Oxygen Ion Sensors?

Negative Oxygen Ion Sensor is an important environmental monitoring device that detects and measures the concentration of negative oxygen ions in the air.

Negative oxygen ions are oxygen molecules or oxygen atoms with one or more negative charges, and they are widely found in the air in nature, especially in natural environments such as mountain forests and waterfalls.

Negative oxygen ions have many benefits for human health, therefore, negative oxygen ion sensors play an important role in people's living and working environment.

First of all, the negative oxygen ion sensor can monitor the concentration of negative oxygen ions in the air in real time.

Through the data collected by the sensor, we can understand the content of negative oxygen ions in indoor or outdoor air, so as to judge the quality of air.

A high concentration of negative oxygen ions helps to improve indoor air quality, purify the air, relieve stress, improve human immunity, and has a calming, sleeping and anti-allergic effect.

Therefore, with the help of negative oxygen ion sensors, we can take appropriate measures to improve indoor air quality and enhance the comfort of living and working.

Secondly, the negative oxygen ion sensor can also be used for the control of indoor air purification equipment.

For example, air purifiers and other equipment usually automatically adjust the working state according to the content of negative oxygen ions in the indoor air, in order to achieve a better air purification effect.

The sensor can monitor the concentration of negative oxygen ions in real time and transmit the data to the control system of the air purifier, so that it can independently determine whether it is necessary to adjust the operating mode to adapt to the changes in the negative oxygen ions in the air.

This is of great significance for improving the attractiveness and popularity of tourist attractions and promoting the development of local tourism.

In conclusion, the anion sensor has the function of real-time monitoring of the concentration of anion in the air, which can be used to improve indoor air quality, control the working effect of air purification equipment, and play an important role in scenes such as tourism and leisure.

Its role is not only to improve the quality of people's living and working environment, but also to promote the development of tourism.

Therefore, the negative oxygen ion sensor is a technology with broad application prospects and important social significance, which is worthy of our in-depth research and application.
