The main body 12 is a cylindrical housing having a space inside which the sensor 11 can be accommodated. The material and color of the main body 12 are not particularly limited, but in this embodiment, the material is made of wood having low thermal conductivity and radiant heat is generated so that the temperature difference and humidity difference of the air inside and outside the main body 12 are as small as possible. The outer surface is painted white so that it can be blocked as much as possible.
In the present embodiment, the shape of the main body 12 is cylindrical, but the shape is not limited to this, and any shape may be used as long as the sensor 11 can be accommodated inside without contacting the inner wall. For example, it may have a polygonal prismatic shape such as a hollow quadrangle.

On the side surface of the main body 12, two types of vents (first vent 19, second vent 20) that penetrate the side wall of the main body 12 and communicate the inside and the outside of the main body 12 are provided in height. It is formed in different positions. A plurality of first vents 19 are formed in the upper portion of the main body portion 12, and a plurality of second vents 20 are formed in positions relatively lower than the first vents 19. Further, the first vent 19 and the second vent 20 are formed by through holes having a circular opening shape, and the opening area of each first vent 19 is the opening of each second vent 20. Larger than the area. Further, the number of the first vents 19 is set to be smaller than the number of the second vents 20.
In this way, the air flow inside the main body 12 is ensured by the first vent 19 and the second vent 20 having the above configuration.
The first vent 19 and the second vent 20 may have any shape, for example, a slit or the like, as long as they penetrate the side wall of the main body 12 and communicate the inside and the outside of the main body 12. There may be. Further, the shapes of the openings of the first vent 19 and the second vent 20 may be different, and the sizes may be the same, or one of them may be larger.

The main body 12 is open in the upward direction, but closed in the downward direction. However, a drainage port 22 communicating with the outside is provided in a substantially central portion of the bottom surface. Further, a tapered portion 21 is formed around the drainage port 22, and a substantially central portion where the drainage port 22 is located is at a relatively low position. Further, the tapered portion 21 may be provided with a partition (not shown) that guides water to the drain port 22.
With the above configuration, it is possible to prevent radiant heat from the ground and prevent the temperature inside the main body 12 from rising, and to efficiently drain the water that has entered the inside of the main body 12 to the outside through the drain port 22.

The hood portion 13 is an umbrella-shaped member having a wide hem that is detachably attached above the main body portion 12. Like the main body portion 12, the hood portion 13 is also made of wood having low thermal conductivity. The outer shape of the hood portion 13 is set to be slightly wider than the outer shape of the main body portion 12, and specifically, the diameter of the hood portion 13 is set to be larger than the diameter of the main body portion 12. A through hole 23 for passing the sensor 11 is formed in the substantially central portion of the hood portion 13 in the vertical direction.

The lid portion 14 is a plate-shaped member that is detachably attached above the main body portion 12 and closes the opening of the main body portion 12. The outer shape of the lid portion 14 matches the outer peripheral shape of the main body portion 12, and in the present embodiment, the lid portion 14 has a circular shape in accordance with the cylindrical main body portion 12. A through hole 24 for passing the sensor 11 is formed in the substantially central portion of the lid portion 14 in the vertical direction.

There is.
In this way, two types of vents, a first vent 19 and a second vent 20, are provided at different heights, and an air flow is generated between the first vent 19 and the second vent 20. By doing so, air can be taken into the main body 12 and the air can flow, so that there is almost no temperature difference between the inside and the outside of the main body 12. Further, since the first vent 19 is covered by the hood portion 13 in a state where it can be ventilated, the inside of the main body portion 12 is at least from above and laterally while ensuring the air flow inside the main body portion 12. It is possible to prevent the ingress of water.
At this time, since the sensor 11 is fixed at a position below the first vent 19 and above the second vent 20, the temperature of the air flowing inside the main body 12 is optimally positioned. In addition, the sensing unit 15 of the sensor 11 does not get wet with water.

Further, since the bottom surface of the main body portion 12 is closed, heat is prevented from rising from below such as the ground and the temperature inside the main body portion 12 is prevented from rising, and the main body portion 12 is provided from a drain port 22 provided at a substantially central portion of the bottom surface. Even if water enters the main body 12 from the second vent 20, the water is drained. At this time, since the sensor 11 is fixed at a position above the second vent 20, the sensing portion 15 of the sensor 11 does not get wet with water.

As described above, the environment monitoring device 10 of the present embodiment has a small number of parts and has a compact and simple configuration, but secures the fluidity of air inside the main body 12 and has a temperature difference between the inside and outside of the main body 12. Since the sensing unit 15 of the sensor 11 housed inside the main body 12 does not get wet, it is possible to prevent a measurement error caused by the influence of watering, rain, or the like.

Further, as shown in FIG. 4, the environmental monitoring device 10 in the above embodiment may be integrally provided with a leg portion 25 such as a tripod or a base that supports the environmental monitoring device 10 below the main body portion 12. .. The environmental monitoring device 10 of the present embodiment is used by suspending it vertically or slightly diagonally from above by a wire or the like (not shown), or by placing it on the ground or the like, and includes legs 25. As a result, even when the environment monitoring device 10 is used by placing it on the ground or the like, it can be stably installed.

Further, as shown in FIG. 4, the environment monitoring device 10 in the above embodiment includes a wireless device 26 capable of communicating the measurement data measured by the sensor 11 with the outside at a position inside the main body 12 so as not to get wet with water. It can also be accommodated. This makes it possible to transmit measurement data to the outside (server, other communication terminal, etc.) without preparing wiring equipment. Therefore, the usability is improved, and the accurate environmental values such as temperature and humidity can be confirmed remotely at a lower cost.

Here, a specific usage mode of the environment monitoring device 10 will be described.

It is possible, and data indicating the measurement result by the sensor 11 is transmitted to those communication terminals (or a server or the like) at regular intervals or at predetermined timings.
As a result, the grower of the crop can easily confirm the environmental values such as the temperature and humidity of the cultivated area of the crop in real time at a remote place through his / her communication terminal. Moreover, in the present embodiment, even if the environment monitoring device 10 is splashed with water due to watering, rain, or the like, water droplets do not adhere to the sensing unit 15 of the sensor 11 and the sensor 11 does not get wet, so that a measurement error does not occur and the crop is cultivated. Environmental values such as temperature and humidity can be measured accurately. Therefore, the grower of the crop in a remote place can obtain accurate information on the environmental value, and can sufficiently grow the crop in an appropriate environment.
