Description
[technical field]
The utility model relates to a kind of microwave sensor.
[background technology]
Radar inductive switch, also known as microwave inductive switch, according to based on Doppler effect, adopt state-of-the-art flat plane antenna, effectively can suppress the interference of higher hamonic wave and other clutters, having the advantages such as highly sensitive, reliability is strong, safe ready, intelligent power saving, is the modern first-selected product of intelligent building and estate management.Micro Energy Lose, multiple functional, all kinds of light fixture can be with, but existing product often cannot put into some light fixture because volume is too large, causes product limitation when client uses larger.
Given this, the necessary microwave sensor providing a kind of improvement, to overcome the defect of prior art existence.
[utility model content]
The purpose of this utility model is to provide a kind of little microwave sensor that takes up room.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of microwave sensor, comprise upper cover, the bottom be fixed together with upper cover, be arranged on the wiring board in upper cover and bottom, light-operated potentiometer is on circuit boards installed, time potentiometer and sensitivity potentiometer, respectively with light-operated potentiometer, time potentiometer is connected with sensitivity potentiometer and exposed some potentiometer knobs, by rotating the light-operated potentiometer on the adjustable wiring board of potentiometer knob, time potentiometer and sensitivity potentiometer, described microwave sensor also comprises connection on circuit boards and exposed photodiode band line, light-operated part on microwave sensor described in described photodiode band bundle of lines is drawn and is exposed.
The utility model defines further, and described bottom is provided with buckle, and described bottom is fixed together by buckle and upper cover.
The utility model defines further, and described bottom is provided with perforate, and described some potentiometer knobs are connected with sensitivity potentiometer with light-operated potentiometer, time potentiometer respectively through the perforate on bottom.
The utility model defines further, and described microwave sensor also comprises the photosensitive outer cover be fixed on photodiode band line.
The utility model defines further, and described microwave sensor also comprises the link cover of FIG that is fixed on and covers with fixing photodiode band line.
The utility model defines further, and described microwave sensor also comprises screw link cover of FIG being fixed on and covering.
Compared with correlation technique, the utility model microwave sensor is drawn by the light-operated part on photodiode band bundle of lines inductor and is exposed, and need not arrange the inductive probe of protrusion, make the utility model microwave sensor volume little, take up room little.
[accompanying drawing explanation]
Fig. 1 is the exploded view of the utility model microwave sensor;
Fig. 2 is the constitutional diagram of the utility model microwave sensor;
Fig. 3 is the side view of the utility model microwave sensor; And
Fig. 4 is the rearview of the utility model microwave sensor.
[detailed description of the invention]
Refer to shown in Fig. 1, the utility model microwave sensor comprises upper cover 1, wiring board 2, light-operated potentiometer (sign), time potentiometer (sign), sensitivity potentiometer (sign), some potentiometer knobs 6, photodiode band line 3, photosensitive outer cover 4, bottom 5 and link cover of FIG 7.
Refer to shown in Fig. 2 to Fig. 4, wiring board 2 is arranged on upper cover 1 li, and bottom 5 is fixed together with upper cover 1 by buckle 51, wiring board 2 is fixed on the inside simultaneously.Wiring board 2 connects and is provided with light-operated potentiometer, time potentiometer and sensitivity potentiometer.Some exposed potentiometer knobs 6 are connected with sensitivity potentiometer with light-operated potentiometer, time potentiometer respectively through the perforate 52 on bottom 5, light-operated potentiometer during such rotation potentiometer knob 6 on adjustable wiring board 2, time potentiometer and sensitivity potentiometer, thus can play regulate that the ambient light of product requires, the effect of working time length and induction sensitivity.Photodiode band line 3 is connected on wiring board 2, and photosensitive outer cover 4 is fixed on photodiode band line 3.Link cover of FIG 7 is fixed on upper cover 1 by screw 8 with fixing photodiode band line 3.
The microwave induced module of the utility model microwave sensor make use of Doppler radar principle, and the effect of this sensor module transmits faint 5.8Ghz microwave, and electro-magnetic wave contacts will reflect to during object, and product receives reflection wave.When object is when mobile, reflection wave and reflection wave create Doppler effect.The microwave of reflection mixes with the electric wave sending microwave, low frequency signal voltage is transformed at the output of inductor, single-chip microcomputer process in module is delivered to after being amplified by high sensitivity low-pass amplifier, single-chip microcomputer carries out illuminance adjustable potentiometer, sensitivity adjustable potentiometer, delay time adjustable potentiometer after carrying out illuminance, sensitivity sampling again, lights load lamp bubble in conjunction with exporting with the relay way of output after process.When arriving without continuous print induction and delay time, load bulb extinguishes.
The utility model microwave sensor is mainly used in above ceiling, can't see microwave sensor body after installation, and only the light-operated part on microwave sensor is drawn and be exposed, outward appearance is unique novel.
Should be understood that, the foregoing is only preferred forms of the present utility model, it not whole embodiments, the change of those of ordinary skill in the art by reading the utility model description to any equivalence that technical solutions of the utility model are taked, is claim of the present utility model and contains.
