Abstract
Description
Technical Field
[0001] This utility model relates to a sensor, and more particularly to an ambient light sensor. Background Technology
[0002] An illuminance sensor is a device used to detect the intensity of ambient light. Based on the photoelectric effect, it converts light signals into electrical signals and outputs them. It is widely used in industries, agriculture, construction and other fields to achieve accurate light monitoring and control. Its core principle is to use photosensitive elements (such as photodiodes or photoresistors) to absorb light energy and generate charges or change the resistance value, thereby generating a voltage or signal that is proportional to the light intensity.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-6 This utility model provides a technical solution: an environmental illuminance sensor, including an illuminance sensor housing 1, an illuminance detection module 101 embedded in the front of the illuminance sensor housing 1, a battery compartment 4 on one side of the illuminance sensor housing 1, a built-in battery 5 placed inside the battery compartment 4, a plug-in mounting groove 402 on the front of the illuminance sensor housing 1, a sealing plate 401 slidably installed in the plug-in mounting groove 402, an external antenna 102 fixedly connected to the other side of the illuminance sensor housing 1, a cable connector 2 fixedly connected to the external antenna 102, a plug-in groove 201 on the cable connector 2, and a limit slot 202 formed on the inner wall of the plug-in groove 201.
[0025] In this embodiment, the illuminance sensor housing 1 is equipped with a signal conversion module and a signal module. The illuminance detection module 101 can detect the ambient light intensity and then transmit the signal to the signal conversion module. The signal conversion module converts the signal into an electrical signal and a wireless signal, which is then transmitted directly to the lamp or the back-end control center via an external antenna 102. The ambient light information collected can be transmitted wirelessly without additional wiring. The built-in battery 5 inside the battery compartment 4 can provide power to the device. Taking a common digital sensor such as OPT3004 as an example, the operating current can be as low as 1.8μA. A single 12000mAh alkaline AA battery can theoretically support continuous operation for about 7.6 years. Considering the wear and tear of other modules, a common battery can work for 1-3 years. The built-in battery 5 needs to be replaced periodically after long-term use.
[0026] To achieve the purpose of connecting cables or sealing when not in use, the device adopts the following technical solution: Fixing feet 103 are symmetrically fixed to both the upper and lower surfaces of the illuminance sensor housing 1; a sealing cap 6 is threaded onto the cable connector 2; a plug assembly 7 is provided above the cable connector 2; the plug assembly 7 includes a plug 701 and a connecting nut 705; a limiting block 702 is fixed to the lower part of the plug 701, and the limiting block 702 cooperates with the limiting groove 202; a transmission cable 704 is fixed to the upper part of the plug 701; a connecting groove 703 is provided on the outer wall of the plug 701; the connecting nut 705 is slidably installed in the connecting groove 703, and the connecting nut 705 is threadedly engaged with the cable connector 2.
[0027] The illuminance sensor housing 1 can be fixed to the wall by fixing foot 103 with bolts. The sealing cover 6 can seal the upper end of the cable connector 2, which can prevent dust and other foreign objects from entering the plug groove 201 when the cable connector 2 is not in use. The connecting nut 705 cooperates with the connecting groove 703. The connecting nut 705 is rotated and installed on the plug 701. After the connecting nut 705 is threaded on the cable connector 2, it can drive the lower end of the plug 701 to be pressed into the plug groove 201. The limiting block 702 cooperates with the limiting groove 202, which can quickly align the pin of the plug 701 with the inner hole of the limiting groove 202.
[0028] To achieve the purpose of fixing the sealing plate 401, the device adopts the following technical solution: a limiting groove 3 is opened on the front of the illuminance sensor housing 1, a return spring 301 is fixedly connected in the limiting groove 3, a limiting pin 302 is fixedly connected to the other end of the return spring 301, a shifting handle 303 is fixedly connected to the limiting pin 302, and a limiting hole 403 is opened in the sealing plate 401, the limiting hole 403 and the limiting pin 302 cooperate with each other.
[0029] The return spring 301 can provide a certain pushing force to the limit pin 302. When the limit pin 302 is pushed, it will insert into the limit hole 403, thereby fixing the sealing plate 401 inside the insertion mounting groove 402. The shift handle 303 can drive the limit pin 302 to move.
[0030] The working principle and usage process of this utility model are as follows: When using it, depending on the application scenario, when it is necessary to use Bluetooth or Wi-Fi to transmit data, the sealing cover 6 needs to be threaded onto the cable connector 2 to seal the plug slot 201. At this time, the device uses the built-in battery 5 to provide power, and the data collected by the illuminance detection module 101 will be transmitted to the collection end through the external antenna 102. When the adapter plug assembly 7 is installed on the cable connector 2, the transmission cable 704 can be used to transmit signals and provide power to the device.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
