[0026] The utility model provides a soil temperature and humidity sensor alarm for greenhouse planting, which has higher temperature and humidity detection accuracy and reduces the probability of false alarms.
[0027] Combine the following Figure 1 to Figure 5 The technical solution provided by the utility model is described in more detail.
[0028] The soil temperature and humidity sensor alarm for greenhouse planting provided by the utility model comprises a bearing body 1, a controller 2 and an alarm device 3, wherein the controller 2 and the alarm device 3 are arranged on the bearing body 1, wherein:
[0029] The bearing body 1 is pre-buried in the greenhouse, and a support structure 4 and a measuring structure 5 are provided at the bottom of the bearing body 1. The measuring structure 5 includes a plurality of first measuring pieces 51 distributed in a circular array along the bottom of the bearing body 1 and a second measuring piece 52 provided in the middle of the bearing body 1. The support structure 4 is used to support the bearing body 1 so that the first measuring piece 51 and the second measuring piece 52 are attached to the soil to be tested.
[0030] The first measuring component 51 , the second measuring component 52 , and the alarm device 3 are all electrically connected to the controller 2 .
[0031] The utility model provides a soil temperature and humidity sensor alarm for greenhouse planting, comprising a bearing body 1, a controller 2 and an alarm device 3, wherein the alarm device 3 is arranged on the bearing body 1, and a measuring structure 5 is arranged at the bottom of the bearing body 1, wherein the measuring structure 5 comprises a first measuring piece 51 and a second measuring piece 52, wherein the first measuring piece 51 and the second measuring piece 52 are both capable of measuring the temperature and humidity of the soil, and by distributing the first measuring piece 51 along a circular array at the bottom of the bearing body 1, the first measuring piece 51 can measure the temperature and humidity of the bottom of the bearing body 1 near the edge, and the second measuring piece 52 is arranged in the middle of the bearing body 1, and can measure the temperature and humidity of the center of the bottom of the bearing body 1, and the temperature and humidity of multiple measuring points at the bottom of the bearing body 1 can be obtained through the first measuring piece 51 and the second measuring piece 52, so that a value closer to the actual temperature and humidity of the soil can be obtained according to the value of the temperature and humidity at the multiple measuring points.
[0032] It is understandable that, when facing the short period after watering is completed, water will flow along the probe to the bottom around the existing probe, resulting in the temperature and humidity values detected by the probe not being the actual temperature and humidity values of the soil. The soil temperature and humidity sensor alarm for greenhouse planting provided by the utility model is used to set the first measuring piece 51 and the second measuring piece 52 at the bottom of the bearing body 1, and the first measuring piece 51 is used to measure the temperature and humidity of the annular periphery of the bearing body 1, and the second measuring piece 52 is used to measure the temperature and humidity of the center of the bearing body 1. The difference between the first measuring piece 51 and the second measuring piece 52 can be used to obtain whether it is in the short period after watering is completed, thereby avoiding the alarm device from falsely alarming. For example: when the first measuring piece 51 detects a temperature of 5 degrees and the second measuring piece 52 detects a temperature of 9 degrees, at this time, the temperature difference between the first measuring piece 51 and the second measuring piece 52 reaches 4 degrees. Since the first measuring piece 51 and the second measuring piece 52 are located close to each other, the temperature difference between the two will not exceed 2 degrees under normal circumstances. Therefore, in the case of such a large temperature difference, the alarm device 3 will not alarm. Similarly, humidity is also detected and monitored using this method, thereby avoiding false alarms from the alarm device 3 .
[0033] It should be noted that the soil temperature and humidity sensor alarm for greenhouse cultivation provided by the utility model, in order to ensure the accuracy of the measurement results of the first measuring piece 51 and the second measuring piece 52, can obtain more accurate temperature and humidity values by summing and averaging the collected data of several first measuring pieces 51, and then summing and averaging the data collected by the second measuring piece 52, thereby effectively ensuring the accuracy of the detection results.
[0034] Furthermore, the first measuring member 51 and the second measuring member 52 are temperature and humidity sensors, and the alarm device 3 is a buzzer. The temperature and humidity sensor is a conventional temperature and humidity detection sensor in the prior art, which is not the core invention of the present invention and will not be described in detail here.
[0035] Furthermore, the support structure 4 includes an insertion portion and an overlapping portion, the insertion portion includes six conical rods 41 arranged at the bottom of the bearing body 1, and the six conical rods 41 are distributed in a circular array; the overlapping portion includes four overlapping protrusions 42, and the overlapping protrusions 42 are arranged at intervals at the bottom of the bearing body 1.
[0036] In a further improvement, the support portion includes an insertion portion and an overlap portion. The insertion portion is composed of six conical rods 41 in a circular array distributed at the bottom of the supporting body 1. The conical rods 41 can be inserted into the soil to fix the supporting body 1 on the soil, ensuring that the supporting body 1 can be effectively fixed when pre-buried; the overlap portion includes four overlap protrusions 42, and the four overlap protrusions 42 are used to support the supporting body 1 to position it above the pre-buried soil to avoid the first measuring piece 51 and the second measuring piece 52 from being excessively squeezed, effectively protecting the first measuring piece 51 and the second measuring piece 52, and avoiding damage to the first measuring piece 51 and the second measuring piece 52.
[0037] It is understandable that the conical rods 41 and the overlapping protrusions 42 can be provided in three, four, five or more numbers to ensure their stability.
[0038] Preferably, the conical rod 41 is arranged corresponding to the first measuring member 51 , and the first measuring member 51 is located on the inner side of the conical rod 41 .
[0039] In this preferred embodiment, the conical rod 41 is arranged corresponding to the first measuring piece 51, and the first measuring piece 51 is arranged on the inner side of the conical rod 41. By setting the first measuring piece 51 on the inner side of the conical rod 41, the problem of abnormal test results caused by the flow of water along the conical rod 41 can be effectively reduced, and the results measured by the first measuring piece 51 are closer to the actual temperature and humidity values.
[0040] Furthermore, the height of the overlapping protrusion 42 is slightly greater than the height of the first measuring piece 51 and the second measuring piece 52. The height of the overlapping protrusion 42 is slightly higher than the height of the first measuring piece 51 and the second measuring piece 52, which can reduce the contact pressure between the first measuring piece 51 and the second measuring piece 52 and the soil during pre-embedding, and effectively protect the first measuring piece 51 and the second measuring piece 52; preferably, the height of the overlapping protrusion 42 is 1-3 mm greater than the height of the first measuring piece 51 and the second measuring piece 52.
[0041] Optionally, a plurality of filter holes 11 are provided on the carrier body 1 , and the filter holes 11 are provided at a middle position between the first measuring member 51 and the second measuring member 52 .
[0042] It can be understood that by setting the filter holes 11, when the area of the supporting body is large, the water above the supporting body can penetrate downward through the filter holes 11, so that the bottom of the supporting body 1 can penetrate in time after watering, ensuring that the temperature and humidity around the second measuring piece 52 and the first measuring piece 51 are consistent with the temperature and humidity levels of other areas.
[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
