Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] As Figures 1 - 3 shown, a soil temperature and humidity sensor of the present invention includes a housing 1, a plurality of probe rods 2, a plurality of insertion rods 3, a battery box 4, an antenna 5, and a display screen 6, and is used to detect the temperature, humidity, and conductivity of the soil.

[0031] Among them, the housing 1 is used to carry other components.

[0032] The probe rod 2 is used to insert into the soil to collect the temperature, humidity and conductivity information of the soil.

[0033] The insertion rod 3 is used to protect the probe rod 2. The insertion rod 3 and the probe rod 2 are fixedly arranged on the same side of the housing 1. The distance that the insertion rod 3 extends out of the housing 1 is greater than the distance that the probe rod 2 extends out of the housing 1, and the insertion rod 3 and the probe rod 2 are arranged in parallel; the number of the insertion rods 3 is equal to the number of the probe rods 2, and their layout positions and layout distances are the same; when it is necessary to detect the soil with relatively hard texture or detect the deep soil, first insert the insertion rod 3 into the position to be measured of the soil, then pull out the insertion rod 3, and then insert the probe rod 2 into this position. The insertion rod 3 plays a role in loosening the soil to be measured, avoiding damage to the probe rod 2 caused by the soil when directly inserting the probe rod 2 into the soil; at the same time, when the probe rod 2 is inserted into the soil, the insertion rod 3 is also inserted into the soil, so that it can also play a role in assisting in fixing this sensor, improving the fixing stability of this sensor.

[0034] As Figure 3 shown, the side of the housing 1 where the probe rod 2 is arranged is the installation side 101, and the installation side 101 is rectangular; as Figure 1 shown, preferably three probe rods 2 are arranged, and the three probe rods 2 are arranged at equal intervals along the length direction of the installation side 101; correspondingly, preferably, the insertion rod 3 and the probe rod 2 with corresponding layout positions are arranged at intervals along the width direction of the installation side 101, so that the three probe rods 2 and the three insertion rods 3 are distributed in a rectangular arrangement, reducing the occupied space and improving the convenience of use.

[0035] As Figure 2 shown, the probe rod 2 includes a connecting rod 21, a temperature probe 22, a humidity probe 23 and a conductivity probe 24. The connecting rod 21 is fixedly arranged on the housing 1; the temperature probe 22, the humidity probe 23 and the conductivity probe 24 are all fixedly arranged at one end of the connecting rod 21 away from the housing 1 to respectively detect the temperature, humidity and conductivity of the soil. Among them, the detection principles of the temperature probe 22, the humidity probe 23 and the conductivity probe 24 are prior arts.

[0036] The temperature probe 22, the humidity probe 23 and the conductivity probe 24 are arranged in parallel and at intervals, and are arranged along a straight path, so as to optimize the overall layout of the probe rod 2.

[0037] The connecting rod 21 plays a role in conducting electricity, and is used to electrically connect the temperature probe 22, the humidity probe 23 and the conductivity probe 24 with the main control board and the single-chip microcomputer inside the housing 1. In order to ensure the firmness of the fixation of the connecting rod 21 to the housing 1 and the strength of the electrical connection structure of the connecting rod 21, preferably, the connecting rod 21 is fixedly penetrated through the housing 1.

[0038] AsFigure 2 As shown in the figure, the housing 1 includes an outer shell 11 and a plurality of waterproof sleeves 12. The waterproof sleeves 12 are fixedly penetrated on the outer shell 11. The connecting rod 21 is penetrated and fixedly sealed in the waterproof sleeve 12, and the connecting rod 21 corresponds to the waterproof sleeve 12 one by one. The waterproof sleeve 12 is sleeved outside the connecting rod 21, which can not only be in sealed contact with it to prevent water stains from entering the interior of the outer shell 11, but also assist in supporting the connecting rod 21 to improve its structural strength.

[0039] In order to facilitate inserting the insertion rod 3 into the soil, it is preferred that the end of the insertion rod 3 away from the housing 1 is in a pointed shape.

[0040] The battery box 4 is used to supply power to components such as the main control board and the single-chip microcomputer in the housing 1. The battery box 4 is fixedly arranged in the housing 1. As Figure 3 shown, the battery box 4 is in contact with the installation side 101. When the insertion rod 3 is inserted into the soil, the battery box 4 can support the position on the housing 1 corresponding to the position of the insertion rod 3, thereby improving the structural strength of the housing 1.

[0041] The antenna 5 is used to realize wireless data transmission. The antenna 5 is fixedly arranged on the housing 1, and the antenna 5 is arranged opposite to the insertion rod 3. Its wireless transmission principle is the prior art.

[0042] The display screen 6 is used to present the data detected by the probe rod 2 in real time. The display screen 6 is fixedly arranged on the housing 1, and its imaging principle is the prior art.

[0043] The usage method of a soil temperature and humidity sensor of the present utility model is as follows:

[0044] First, hold and move the housing 1, insert the insertion rod 3 into the soil to be measured, then pull out the insertion rod 3, then insert the probe rod 2 into the position where the insertion rod 3 was originally inserted into the soil, and finally start this sensor to detect the temperature, humidity and conductivity data of the soil in real time.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
