Description

technical field [0001] The invention relates to the technical field of artificial fume stress, in particular to a fume system based on wireless sensing technology and a manufacturing method thereof. Background technique [0002] There are more and more experiments on plant gas stress at home and abroad. The fumigation device can simulate the environment of polluted gas stress, which is convenient for setting the concentration of pollutants and the environmental conditions during fumigation. However, most of the fumigation devices currently used are open-terminal. The fumigation box cannot strictly control the gas concentration in the fume box to keep it stable, and it is easy to cause large experimental errors. In addition, most of the gas concentration monitoring in the past used manual sampling, which could not monitor the concentration change of the polluted gas in real time, and the previous fumigation The fumigation device only studies the impact of gas concentration ch...

[0002] There are more and more experiments on plant gas stress at home and abroad. The fumigation device can simulate the environment of polluted gas stress, which is convenient for setting the concentration of pollutants and the environmental conditions during fumigation. However, most of the fumigation devices currently used are open-terminal. The fumigation box cannot strictly control the gas concentration in the fume box to keep it stable, and it is easy to cause large experimental errors. In addition, most of the gas concentration monitoring in the past used manual sampling, which could not monitor the concentration change of the polluted gas in real time, and the previous fumigation The fumigation device only studies the impact of gas concentration changes on plants, without controlling environmental factors such as light, temperature, and humidity, so it is impossible to observe the impact of the combined action of the environment and polluted gases on plants. The polluted gas is sent to each fume box, and the gas flow in each channel cannot be accurately and precisely controlled. Therefore, the gas concentration of each fume box is also quite different from the experimental requirements, and some fume coercion schemes have very high requirements for laboratory hardware. High, the experimenters cannot check the gas concentration change data anytime and anywhere, the degree of automation is not high, and it cannot be widely used. Therefore, this invention proposes a fume gas system based on wireless sensing technology
