[0026] Please refer to Figures 1-2 , Figure 1 This is a 3D view of the PIR sensor test chamber. Figure 2 This is a schematic diagram of the enclosure. This embodiment provides a PIR sensor test enclosure, which includes a housing 1, a main control board (not shown in the figure), a wind and solar power test component 2, and an RF test component 3. The housing 1 is hollow and its interior is divided into a first test space 11 and a second test space 12. The wind and solar power test component 2 is disposed in the first test space 11, and the RF test component 3 is disposed in the second test space 12.

[0027] Specifically, the housing 1 includes a housing 13 and a cover 14, with one side of the cover 14 rotatably connected to the housing 13. The first test space 11 and the second test space 12 are spaced apart within the housing 13.

[0028] The wind and light testing assembly 2 provides a wind source and light source environment for the PIR sensor to test its sensitivity in a wind and light environment. Specifically, the wind and light testing assembly 2 includes an adjustable light source 21 and a fan 22, which are electrically connected to the main control board. The first test space 11 includes a light source area 111, a wind source area 112, and a first test area 113, and these areas are interconnected. The adjustable light source 21 is installed in the light source area 111, with its light-emitting end facing the first test area 113. A mounting groove 1121 is provided on one side of the wind source area 112, with an opening facing the first test area 113. The fan 22 is located in the mounting groove 1121, with its air outlet facing the opening, so that the air outlet of the fan 22 faces the first test area 113. A first data transmission board 23 is provided in the first test area 113, and the first data transmission board 23 is provided with contacts. The first data transmission board 23 is used to electrically connect with the PIR sensor to read the data of the PIR sensor, and the contacts on the first transmission board 23 are used to electrically connect with the pins of the PIR sensor.

[0029] In practical use, the PIR sensor is placed in the first test area 113 and electrically connected to the first data transmission board 23. The main control board controls the operation of either the adjustable light source 21 or the fan 22. When the adjustable light source 21 is on, it emits light towards the PIR sensor; when the fan 22 is on, it blows air towards the PIR sensor. This simulates different test environments for the PIR sensor. It should be noted that the adjustable light source 21 and fan 22 can be activated simultaneously according to actual test requirements, and the brightness of the adjustable light source 21 and the airflow of the fan 22 can be adjusted via the main control board to provide more diverse test environments for the PIR sensor.

[0030] Please refer to Figure 3 and Figure 4 , Figure 3 This is an exploded view of the PIR sensor test chamber. Figure 4 This is another exploded view of the PIR sensor test box. Further, the wind and solar test assembly 2 also includes a first shielding plate 24, a light-shielding plate 25, and a wind-blocking plate 26. The first shielding plate 24 is slidably disposed above the wind source area 112 and the first test area 113. When the first shielding plate 24 slides, it can move above the wind source area 112 and the test area 113. When the first shielding plate 24 moves from above the wind source area 112 to above the test area 113, it can cover the first test area 113. Sliding grooves 1111 are respectively provided on opposite sides of the light source area 111. The light-shielding plate 25 is movably inserted into the sliding grooves 1111 to block the light-emitting end of the adjustable light source 21. A first snap-fit ​​groove 1122 is formed between the wind source area 112 and the first test area 113. The wind-blocking plate 26 is movably inserted into the first snap-fit ​​groove 1122 to block the path between the fan 22 and the first test area.

[0031] The first shielding plate 24, the light shielding plate 25, and the wind shielding plate 26 are used to block interference from other conditions during the testing of the PIR sensor. For example, when it is necessary to test the sensitivity of the PIR sensor only in a windy environment, the first shielding plate 24 is slid so that it is positioned above the first test area 113 to cover the first test area 113 and prevent external conditions from interfering with the environment of the first test area 113. The light shielding plate 25 is inserted into the sliding groove 1111 so that it blocks the light emitted by the adjustable light source 21, preventing the light emitted by the adjustable light source 21 from shining on the PIR sensor located in the first test area 113.

[0032] When testing the sensitivity of the PIR sensor under illumination, a baffle 26 is inserted into the first slot 1122 to block the airflow from the fan 22. It should be noted that the baffle 26 is transparent, allowing light emitted from the adjustable light source 21 to pass through and illuminate the PIR sensor located in the first test area 113. Preferably, the adjustable light source 21 in this example is a full-spectrum halogen spotlight, which can emit light of multiple wavelengths, making it closer to natural light. A 24V DC fan 22 is used.

[0033] The wind and solar test assembly 2 also includes a heat insulation plate 28. A second snap-fit ​​groove 1112 is formed between the light source area 111 and the wind source area 112, and the heat insulation plate 28 is movably inserted into the second snap-fit ​​groove 1112. The heat insulation plate 28 is used to block the temperature emitted by the adjustable light source 21, so as to avoid the heat emitted by the adjustable light source 21 from affecting the test of the PIR sensor during the test.

[0034] Furthermore, the wind and solar test assembly 2 also includes a heat source 27. The heat source 27 is located within the mounting slot 1121, and the air outlet of the fan 22 faces the heat source 27. The heat source 27 is electrically connected to and controlled by the main control board. In this example, the heat source 27 is a PTC heating plate.

[0035] The wind and solar test component 2 also includes a temperature sensor 5 and a light sensor 4. Both the temperature sensor 5 and the light sensor are located in the first test area 113, and are electrically connected to the first data transmission board 23. The temperature sensor 5 is used to detect temperature data in the first test space 11, and the light sensor 4 is used to detect illuminance data in the first test space 11. The illuminance data and ambient temperature data are fed back to the main control board through the first data transmission board, facilitating the main control board's monitoring of environmental data in the first test space 11.

[0036] Please refer to Figures 2-4 and Figure 5 , Figure 5 This is a cross-sectional view of the PIR sensor test box. The RF test assembly 3 includes an RF source 31. The second test space 12 is divided into a second test area 121 and a mounting area 122. A through hole 120 is provided between the second test area 121 and the mounting area 122, and the second test area 121 is connected to the mounting area through the through hole 120. The RF source 31 is located in the mounting area 122, and the RF of the RF source 31 illuminates the second test area 121 through the through hole 120. A second data transmission board 32 is provided in the second test area 121, and the second data transmission board 32 is electrically connected to the main control board. The second data transmission board 32 is provided with contacts.

[0037] When testing the PIR sensor in a radio frequency (RF) environment, the PIR sensor is placed in the second test area 121 and electrically connected to the second data transmission board 32 via contacts. The RF source 31 is then turned on, transmitting RF signals to the second test area to simulate the PIR sensor in an RF environment. The second data transmission board 32 reads the data from the PIR sensor and sends it to the main control board. In this example, the RF source 31 uses a 2.4G RF module.

[0038] The RF test assembly 3 also includes a second shield 33, which is slidably disposed above the second test area 121 and the mounting area 122. When the PIR sensor is placed in the second test area 121 for testing, the second shield 33 is slid to move above the second test area 121, covering the second test area 121 to ensure that the test environment of the second test area 121 is not disturbed.

[0039] Preferably, the second data transmission board 32 is also provided with a temperature sensor 5 and a light sensor 4. The temperature sensor 5 and the light sensor 4 are located in the second test area 121 to test the environmental data of the second test area 121.

[0040] In summary, by dividing the housing 1 into a first test space 11 and a second test space 12, and placing the wind and solar test component 2 and the radio frequency test component 3 in the first test space 11 and the second test space 12 respectively, the testing requirements of PIR in different environments can be met. Furthermore, by placing the wind and solar test component 2 and the radio frequency test component 3 in the housing 1, the volume of the PIR sensor test box is effectively reduced, making it easier to carry.

Various modifications and variations can be made to this utility model by those skilled in the art.
