LoRaWAN Phosphine (PH3) Gas Sensor

Environmental LoRaWAN Phosphine (PH3) Sensor

xiamen ZONEWU LoRaWAN Phosphine (PH3) Sensor is a new gas monitoring device made using LoRa wireless technology, which relies on a wireless method called spread spectrum modulation to transmit data and can remotely monitor phosphine gas in the environment.

xiamen ZoneWu LoRaWAN Gas Sensor PH3 Sensor Features:

This is a particularly powerful wireless gas sensor. Can collect data on the concentration, temperature, and humidity of phosphine in the environment, and closely monitor whether there are any changes in the data. At the same time, it can transmit data so that we can know the on-site situation at any time.

It uses powerful LoRa wireless technology, which allows sensors and other devices to transmit signals to each other over long distances. In addition, the three electrode electrochemical gas detection probe inside works together with a high-performance "data processing chip": the probe is specifically responsible for accurately measuring the concentration of phosphine, and the chip is like a fast reacting brain, responsible for quickly processing this data.

This is a specially designed instrument for measuring phosphine gas, which can immediately detect even a small amount of phosphine in the air. At the same time, it also carries temperature and humidity measuring parts on its body, which can always know whether the surrounding environment is cold or hot, and how humid it is. In addition, it has a special temperature sensing device that can adjust the measurement results according to temperature changes. Regardless of whether the weather is freezing cold or scorching hot, the measured concentration of phosphine is accurate.

This sensor is particularly sensitive, as long as there is slightly more or less phosphine gas in the air, it can immediately detect it. When measuring data, it is also particularly "meticulous", even if the changes are very small, they can be accurately measured. And it is very "reliable" and not easily affected by the clutter around it. Even if the environment is particularly complex, it can continue to work normally without making mistakes.

A safety value can be set in advance based on the on-site situation. As long as the detected concentration of phosphine gas is higher or lower than this number, it will immediately "report" so that we can take measures as soon as possible.

It can be used in many places, such as checking whether the residual phosphine in grain after fumigation in the granary exceeds the standard; Keep an eye on whether there is any phosphine leakage during the production of the chemical plant; Even places like sewage treatment plants and garbage disposal sites can use it to check for the production of phosphine, ensuring everyone's safety and a clean environment.

Technical Parameters

Product Applications

1. High sensitivity and fast response: This sensor is particularly "smart", even if there is only a little bit of phosphine in the air, it can instantly detect and calculate the concentration, and immediately alarm if something is wrong. Fast response and high sensitivity, which can reduce safety risks and save a lot of time for emergency response.   

2. Anti interference and ultra stable: No matter the temperature fluctuates, humidity changes, or other gases around it cause trouble, it can work steadily for a long time without any problems, and the measured data is always reliable.   

3. Strong recognition ability: It can accurately distinguish phosphine from other similar gases, and will never mistake other gases for phosphine, greatly reducing false alarms and missed alarms. The monitoring results are more accurate and reassuring.

4. Not afraid of interference and reliable: Even in complex factories full of various interferences, it can quickly capture the subtle changes of phosphine and provide real data, helping us to make environmental monitoring clear and transparent.

Common knowledge of  PH3 

What is the explosive limit of phosphine? How to use LEL to indicate the degree of danger

When phosphine is mixed with air to a certain concentration, it will explode when exposed to an open flame, and this explosive concentration range is called the explosive limit. For example, the lower explosive limit (LEL) of phosphine is 1.85%, and the upper limit is 26%. When the concentration of phosphine in the air reaches 1.85% LEL, it belongs to the "lowest hazardous concentration that can explode", and the higher the concentration, the more dangerous it is.

How to convert the LEL and VOL% concentrations of phosphine

To convert, we need to know that the lower explosive limit of phosphine is 1.85% VOL (i.e. 100% LEL=1.85% VOL). For example, when 20% LEL is detected, the actual concentration is 1.85% VOL x 20%=0.37% VOL. The formula can be written as: VOL% concentration=LEL percentage x 1.85%.

How to convert the concentration units of phosphine from ppm to mg/m ³

Both ppm and mg/m ³ can represent concentration. When converting, the molecular weight of phosphine (34) should be used, and the formula is approximately: mg/m ³=ppm × 34 ÷ 22.4. For example, converting 10ppm phosphine to mg/m ³ is 10 × 34 ÷ 22.4 ≈ 15.18mg/m ³, which facilitates checking whether the concentration exceeds the standard under different standards.

What is the safe concentration of phosphine in the work environment?

Answer: In order to ensure safety, the concentration of phosphine in workshops and other workplaces should generally not exceed 0.3ppm (approximately 0.45mg/m ³). If the concentration exceeds this value, it is necessary to ventilate or evacuate quickly, as phosphine is not only flammable but also highly toxic, and excessive inhalation can harm health.

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.
