[0023] This application discloses a temperature and humidity detection module, which is described in an embodiment. Figure 1 and Figure 2The system includes a motherboard 1 and a temperature and humidity detection sensing system 2. A control chip 3 is electrically connected to the front top of the motherboard 1. A temperature and humidity sensor unit 4 is electrically connected to the rear top of the motherboard 1. A Bluetooth sensing unit 5 is electrically connected to the right top of the motherboard 1. Wiring terminals 6 are electrically connected to the front and rear sides of the left top of the motherboard 1. A WiFi communication unit 7 is located on the left top of the motherboard 1. The pins on the front and rear bottom of the WiFi communication unit 7 are electrically connected to the wiring terminals 6. A positioning structure 8 is located on the outside of the WiFi communication unit 7. The temperature and humidity detection sensing system 2 includes a control terminal 201, a temperature and humidity detection module 202, a Bluetooth module 203, and a Wi-Fi sensor 5. The output terminals of the iFi module 204 and the temperature and humidity detection module 202 are unidirectionally electrically connected to the receiving terminal of the control terminal 201. The receiving terminal of the Bluetooth module 203 is unidirectionally electrically connected to the output terminal of the control terminal 201. The WiFi module 204 is unidirectionally electrically connected to the output terminal of the control terminal 201. The receiving terminal of the temperature and humidity detection sensing system 2 is unidirectionally electrically connected to the power supply module 205. The control terminal 201 is the control chip 3. The temperature and humidity detection module 202 is the temperature and humidity sensor unit 4. The Bluetooth module 203 is the Bluetooth sensing unit 5. The WiFi module 204 is the WiFi communication unit 7. By setting the temperature and humidity detection sensing system 2 and the positioning terminal... Structure 8, powered by power supply module 205, supplies power to temperature and humidity detection sensing system 2. Temperature and humidity sensor unit 4 accurately senses ambient temperature and humidity data, quickly converts it into electrical signals, and transmits them unidirectionally to control terminal 201 of control chip 3. After receiving the signal, control terminal 201 amplifies, filters, and analyzes the data to improve data quality. The processed data is then transmitted unidirectionally to Bluetooth module 203 of Bluetooth sensing unit 5 and WiFi module 204 of WiFi communication unit 7. Bluetooth module 203, using Bluetooth technology, can quickly pair with nearby smart devices such as smartphones and tablets to achieve real-time sharing of temperature and humidity data within a small area. WiFi module... The 204 module utilizes a WiFi network to overcome distance limitations and stably transmit data to remote devices or cloud servers, meeting the needs of complex scenarios such as remote control of smart homes and big data analysis of industrial IoT. At the same time, the positioning structure 8 on the outside of the WiFi communication unit 7 can stabilize the WiFi communication unit 7 under vibration and collision during operation, ensuring its reliable electrical connection with the wiring terminal 6 and maintaining stable and continuous data transmission. During installation, this positioning design simplifies the process, improves efficiency, and facilitates the disassembly and replacement of the WiFi communication unit 7 to connect other similar modules when upgrades or replacements are needed, optimizing transmission performance and ensuring the overall performance of the module.

[0024] Reference Figure 2The positioning structure 8 includes a limiting rod 801 bolted to the left side of the main board 1. The limiting rod 801 is located outside the WiFi communication unit 7. A positioning sleeve 802 is fixedly connected to the front side of the limiting rod 801. By setting the limiting rod 801 and the positioning sleeve 802, the limiting rod 801 is bolted to the left side of the main board 1 and located outside the WiFi communication unit 7, providing lateral support and limiting it, preventing the WiFi communication unit 7 from being displaced in the horizontal direction due to equipment vibration and shaking. The positioning sleeve 802 is fixedly connected to the front side of the limiting rod 801. After the WiFi communication unit 7 is installed in place, the positioning sleeve 802 facilitates the subsequent positioning of the WiFi communication unit 7.

[0025] Reference Figure 2 A rotating sleeve 803 is fixedly connected to the rear side of the limiting rod 801, and a cover plate 804 is provided on the top of the limiting rod 801. The rear side of the cover plate 804 is rotatably connected to the inside of the rotating sleeve 803. The cover plate 804 is located on the top of the WiFi communication unit 7. By setting the rotating sleeve 803 and the cover plate 804, the rotating sleeve 803 on the rear side of the limiting rod 801 provides a flexible rotation fulcrum for the cover plate 804. When installing the WiFi communication unit 7, the cover plate 804 can be flipped back through the rotating sleeve 803, which makes it convenient for the operator to accurately place the WiFi communication unit 7 in the designated position on the main board 1, avoiding the cover plate 804 from obstructing the installation and causing inconvenience. After installation, the cover plate 804 is rotated back to its original position so that it covers the top of the WiFi communication unit 7 and protects it from above.

[0026] Reference Figure 2 Both sides of the front of the cover plate 804 are fixedly connected with locking posts 805. The locking posts 805 are engaged inside the positioning sleeve 802. By setting the locking posts 805, the locking posts 805 on both sides of the front of the cover plate 804 are tightly engaged with the inside of the positioning sleeve 802. This design cleverly enhances the fixing effect of the cover plate 804 on the WiFi communication unit 7. When the cover plate 804 is closed, the locking posts 805 act like strong locks, firmly fixing the cover plate 804 to the positioning sleeve 802, so that the cover plate 804 will not be lifted due to slight vibration during the operation of the equipment. This further stabilizes the protective structure of the WiFi communication unit 7 and forms a complete three-dimensional fixing system with the limit rod 801 and the positioning sleeve 802, ensuring the stability of the WiFi communication unit 7 in all aspects.

[0027] Reference Figure 4An anti-static rubber pad 9 is embedded on the inner side of the limiting rod 801. The inner side of the anti-static rubber pad 9 contacts the outer side of the WiFi communication unit 7. By setting the anti-static rubber pad 9, the anti-static rubber pad 9 embedded on the inner side of the limiting rod 801 plays a key role in electrostatic protection. In the operating environment of electronic equipment, static electricity is easy to accumulate and damage the sensitive WiFi communication unit 7. Timely conduction of static electricity eliminates the potential for static electricity hazards, ensures the stable operation of the internal circuit of the WiFi communication unit 7, ensures that data transmission is not interfered with by static electricity, extends its service life, and improves the reliability of the entire module.

[0028] Reference Figure 2 Rubber rods 10 are bonded to the front and rear sides of the top of the cover plate 804. The rubber rods 10 are located on the outside of the WiFi communication unit 7. By setting the rubber rods 10, the rubber rods 10 on the front and rear sides of the top of the cover plate 804 are located on the outside of the WiFi communication unit 7. When the device is subjected to a slight collision, they play a role in buffering and shock absorption, avoiding direct impact of external forces on the WiFi communication unit 7, protecting its shell and internal precision components, providing an additional protective barrier for the WiFi communication unit 7, and helping to ensure its stable operation.

[0029] Reference Figure 2 The top of the cover plate 804 is provided with a slot 11. The slot 11 is located on the top of the WiFi communication unit 7. By setting the slot 11, the WiFi communication unit 7 will generate heat during operation. The heat will be dissipated upward through the slot 11, promoting air circulation and effectively reducing the temperature of the WiFi communication unit 7, so that it can work continuously and efficiently in a suitable temperature environment.

[0030] The implementation principle of a temperature and humidity detection module in this application embodiment is as follows: During operation, the power supply module 205 starts first, providing power support to the temperature and humidity detection sensing system 2. The temperature and humidity sensor unit 4 of the temperature and humidity detection module 202 located on the back of the motherboard 1 accurately senses the temperature and humidity data of the surrounding environment and quickly converts it into an electrical signal, which is transmitted unidirectionally to the control terminal 201 of the control chip 3 on the front of the motherboard 1. After receiving the signal, the control chip 3 performs amplification, filtering, and analysis processing in sequence to make the data accurate and reliable. The processed data is split into two paths, one to the Bluetooth module 203 of the Bluetooth sensing unit 5. With the convenient pairing characteristics of Bluetooth, it can connect with nearby smart devices such as smartphones and tablets. The device connects instantly, easily enabling real-time sharing of temperature and humidity data within a small area, allowing users to monitor their surroundings anytime, anywhere. Another path connects to the WiFi module 204 of the WiFi communication unit 7 on the left. Leveraging the powerful WiFi network, data overcomes spatial limitations and is stably transmitted to remote devices and even cloud servers, laying a solid data foundation for complex applications such as remote control of smart homes and big data analysis of the industrial Internet of Things. The positioning structure 8 on the outside of the WiFi communication unit 7 is a crucial component ensuring the stable operation of the entire system. The limiting rod 801, bolted to the left side of the main board 1, provides robust lateral support and limitation for the WiFi communication unit 7, effectively resisting vibrations during device operation. To prevent horizontal displacement, the positioning sleeve 802 on the front side of the WiFi communication unit 7 is precisely locked in position after installation, ensuring a stable and reliable electrical connection with the terminal block 6, thus safeguarding continuous and stable data transmission. The rotating sleeve 803 on the rear side of the limit rod 801 gives the cover plate 804 the ability to open and close flexibly. During installation, the cover plate 804 can be flipped back using the rotating sleeve 803, allowing the operator to accurately place the WiFi communication unit 7 at the designated location on the main board 1 without obstruction. After installation, the cover plate 804 rotates back to its original position, tightly covering the top of the WiFi communication unit 7. The locking post 805 on the front side of the cover plate 804 is tightly engaged with the positioning sleeve 802, further... The additional fixing effect, together with the limit rod 801 and positioning sleeve 802, forms a stable three-dimensional protection system, ensuring the stability of the WiFi communication unit 7 in all aspects. At the same time, the anti-static rubber pad 9 on the inner side of the limit rod 801 promptly conducts away the static electricity that easily accumulates in the operating environment of electronic equipment, protecting the internal circuit of the WiFi communication unit 7 from static interference, ensuring smooth data transmission, and extending its service life. The rubber rod 10 on the top of the cover plate 804 buffers and absorbs shocks when the device encounters minor collisions, protecting the outer shell and precision components of the WiFi communication unit 7. The holes and slots 11 on the cover plate 804 open up heat dissipation channels for the WiFi communication unit 7, promoting heat dissipation upwards and enabling it to operate efficiently at a suitable temperature.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
