LoRa Nitrogen Dioxide (NO2) Sensor

Environmental LoRaWAN Nitrogen Dioxide  (NO2)  Sensor

xiamen ZONEWU The LoRa NO₂ (Nitrogen Dioxide) sensor is a wireless IoT sensor for monitoring nitrogen dioxide (NO₂) gas.

xiamen ZoneWu LoRaWAN Gas Sensor NO₂ Sensor Features:

This is a wireless Internet of Things sensor that can collect data such as the concentration of nitrogen dioxide, temperature, and humidity in the environment, monitor it, and then transmit the data to help us keep track of relevant information at all times.

It contains a nitrogen dioxide sensor and a temperature and humidity sensor, as well as a high-performance nitrogen dioxide sensor and a microprocessor. With these devices, it can accurately detect the values of nitrogen dioxide, temperature, and humidity in the environment.

The detection data is particularly accurate and will not easily make mistakes. It has stable performance and is not easily affected by external interference. In addition, it consumes less power and has a low cost of use, so you don't have to worry about constantly charging or replacing batteries.

Using LoRa spread spectrum modulation technology, it supports the standard LoRaWAN protocol. It is like having a mobile phone with a super strong signal, which can realize long-distance communication between terminals and transmit the monitored data to a very far place.

A value standard can be set in advance according to the environmental situation. Once the monitored data exceeds or falls below this standard, it will immediately report to us, telling us that the data is abnormal, so that we can handle it in a timely manner.

There are many uses for it! Air quality monitoring stations use it to monitor whether the air is polluted; It is used to check whether the nitrogen dioxide in the exhaust gas exceeds the standard at the industrial exhaust gas emission port; Use it to check indoor air quality; It can also be used to monitor the surrounding air quality in crowded transportation hubs with many people and cars. 

Technical Parameters

Product Applications

1. Long-distance transmission: LoRa technology can transmit data wirelessly to several kilometers away, which is very suitable for monitoring nitrogen dioxide over a large area.

2. High precision detection: especially sensitive to nitrogen dioxide, fast and accurate measurement of concentration, can get accurate data in real time.

3. Strong anti-interference: not afraid of electromagnetic and environmental interference, can work steadily in complex environments.

4. Easy to deploy: small size, simple installation, no need to pull a bunch of wires, can be installed anywhere you want.

Common knowledge of  NO₂ 

What is nitrogen dioxide (NO₂)?What are the characteristics

Nitrogen dioxide is a toxic gas with a reddish-brown color and a pungent odor. It is soluble in water at room temperature and can react with water to form nitric acid and nitrogen oxide (NO). It is one of the main atmospheric pollutants, has strong oxidizing properties, can irritate the respiratory tract, and is also an "accomplice" in the formation of acid rain and photochemical smog.

What is the safe concentration limit of nitrogen dioxide in the air

•  National Air Quality Standard (GB3095 - 2012):

• Annual average: 40 μg / m³ (Class 1 standard, applicable to nature reserves, etc.);

• 24-hour average: 80 μg / m³ (secondary standard, applicable to residential areas, commercial areas, etc.).

• Short-term exposure risk value: when the concentration exceeds 200 μ g / m³, it may cause symptoms such as coughing and shortness of breath;When it exceeds 1000 µg/m³, it will seriously damage the respiratory tract and even lead to pulmonary edema.

How to distinguish between nitrogen dioxide and other similar gases (such as nitrogen oxide)

Color and odor: Nitric oxide (NO) is colorless and odorless. At room temperature, it reacts quickly with oxygen to form NO₂ (red brown, with a pungent odor).

Detection method:

• NO₂ can make the moist starch iodine test paper turn blue (strong oxidizing);

• Professional equipment needs to be distinguished by chemical luminescence (NO needs to be converted into NO₂ before detection).

Why might indoor nitrogen dioxide concentration be overlooked?

• Concealment: NO₂ released by cooking in the kitchen (gas stove combustion), secondhand smoke, etc., is colorless (it turns reddish-brown at high concentrations), and its odor is easily masked by other odors;

• Cumulative risk: Long-term low-concentration exposure (such as poor kitchen ventilation) may cause chronic respiratory inflammation, with symptoms similar to common colds, which are easily overlooked. 

Application Scenarios

Industrial production

Waste gas emission monitoring: Conduct real-time monitoring of industrial waste gas emissions to ensure that waste gases meet emission standards and reduce pollution to the environment.

 

Environmental inspection

Air quality monitoring helps people understand air quality and protect the environment and health by detecting harmful gases such as sulfur dioxide.

Safety protection

In coal mines and tunnels, gas sensors detect toxic and harmful gases such as methane and warn against accidents.
