It includes a sensor 24 . However, various sensors included in the sensor node 1 may be other sensors that are easy to measure gas or fine dust in addition to the illustrated sensors.

The PM 1.0 sensor 21 may detect ultrafine dust having a particle size of 1.0 μm. The PM 10 sensor 22 may detect fine dust having a particle size of 10 μm. However, although not shown, a PM2.5 sensor capable of detecting ultrafine dust having a dust particle size of 2.5 μm may be employed in the sensor node 1 .

As such, the higher the grade of the PM sensors 21 and 22, the higher the detection rate. That is, the PM sensors 21 and 22 may detect dust generated in the livestock complex.

Next, the ammonia sensor 23 and the hydrogen sulfide sensor 24 measure the concentration of gaseous pollutants generated due to manure in the livestock complex.

Specifically, the ammonia sensor 23 is a sensor for measuring the ammonia concentration, and is composed of an ammonium ion selective membrane or an ammonia gas permeable membrane and a complex type hydrogen ion electrode. The ammonia sensor 23 has good selectivity to ammonia and is used for measuring ammonia in pollutants generated from factory wastewater or manure due to the characteristic that it hardly responds to other volatile substances.

Accordingly, it is possible for the user to acquire various gas concentration values and fine dust concentration values measured by the sensor node in real time.

Next, Figure 2 is an external schematic view of the air quality measuring apparatus 100 for livestock according to an embodiment. However, as shown in FIG. 2 , it is shown that the sensor node 20 is installed in the chamber of the air quality measuring apparatus 100 for livestock.

As shown in FIG. 2 , the air quality measuring apparatus 100 for livestock includes a display unit 40 , a uniformizing fan 60 , an outlet unit 70 , and first to third inlets 51 to 53 . In addition, although not shown in FIG. 2, the control unit 30 for controlling the air quality measuring apparatus 100 for livestock and the communication unit 10 for transmitting the measured values measured by the sensor node 20 by wire or wirelessly are additionally included. .

Hereinafter, each configuration of the air quality measuring apparatus 100 for livestock will be described in detail.

First, the first to third inlets 51 to 53 are installed at different positions of the livestock air quality measuring device 100 to suck gas or fine dust in the air of the livestock complex from different directions.

For example, assuming that the air quality measuring apparatus 100 for livestock is a rectangular parallelepiped, as shown in FIG. 2 , the first inlet 51 is parallel to the X-axis direction, and the air quality measuring apparatus for livestock on the YZ plane. A hole is drilled in (100) so that air can be sucked in. Next, the second inlet 52 may suck air by making a hole in the air quality measuring device 100 for livestock on the XZ plane so as to be parallel to the Y-axis direction. Finally, the third inlet 53 may suck air by making a hole in the air quality measuring device 100 for livestock on the YZ plane so as to be parallel to the X-axis direction. At this time, as shown in FIG. 2 , the first inlet 51 and the third inlet 53 may be installed on each side facing each other when the chamber constituting the air quality measuring apparatus 100 for livestock is a hexahedron. have.

Assuming that the livestock air quality measuring device 100 shown in FIG. 2 is a hexahedron, assuming that the measuring device 100 is installed on one wall of the inner wall of the livestock complex, the first from both sides of the measuring device 100 It can be seen that the inlet 51 and the third inlet 53 suck air, and the second inlet 52 sucks air from the front of the measuring device 100 .
