DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will be described in further detail with reference to the accompanying Figure 1 - accompanying Figure 3 drawings to the present application.

[0021] Fix the circuit board 2 in the sealed housing 1. The humidity sensor 3 passes through the sealed housing 1 and is sealed and connected to the sealed housing 1. Then bury the sealed housing 1 in the soil. In this way, the humidity sensor 3 does not need to be connected to the circuit board 2 through a wire, so there is no need to bury a wire in the soil, which can effectively prevent the wire from being damaged during plowing and thus unable to monitor the soil humidity.

[0022] Protect the circuit board 2 through the sealed housing 1, so that the lower half of the monitoring device can be buried in the soil.

[0023] Refer to Figure 1 As shown, the sealed housing 1 includes a sealed barrel body 11. A cone 12 is fixed at the lower end of the sealed barrel body 11, and a sealing cap 13 is installed at the upper end of the sealed barrel body 11; the sealing cap 13 is threadedly connected to the sealed barrel body 11; a sealing ring 14 is arranged between the sealing cap 13 and the sealed barrel body 11; after separating the sealing cap 13 from the sealed barrel body 11, it is convenient to install the circuit board 2 on the sealed barrel body 11; after installing the sealing cap 13, an extrusion force is generated on the sealing ring 14, strengthening the sealing effect.

Clamping plates 22 are fixed at both ends of the circuit board 2, and the outer edges of the clamping plates 22 are in contact with the inner wall of the sealed barrel body 11; the clamping plates 22 and the support frame 21 are connected by bolts; fix the support frame 21 on both sides of the circuit board 2 to make the circuit board 2 have stronger support force. By setting the clamping plates 22 at both ends of the circuit board 2 and making the outer edges of the clamping plates 22 in contact with the inner wall of the sealed barrel body 11, the displacement of the circuit board 2 can be reduced after installing the clamping plates 22, making the structure of the circuit board 2 more stable after installation.

[0026] Refer to Figure 2 As shown, a radio transmission module 25 is installed on the circuit board 2; the wireless transmission module 25 can be Bluetooth or WiFi, which can reduce the use of data lines and facilitate data collection and transmission.

[0027] Refer to Figure 1 As shown, a sealing tube 15 connected to the wire 24 is installed on the sealing cap 13; when the wire 24 passes through the sealing cap 13, the wire 24 is sealed with the sealing tube 15 by glue to reduce the entry of moisture into the sealed housing 1, thereby preventing the circuit board 2 from getting damp.

[0028] Refer to Figure 1, the humidity sensors 3 are arranged in a line from top to bottom on the sealed cylinder body 11, and can collect data on soil humidity at different depths.
