Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
Fig. 1 is the utility model intelligent humidity warning device schematic diagram.
Fig. 2 is the utility model drive amplification circuit diagram.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Below with reference to Fig. 1, Fig. 2, describe the utility model in detail, the utility model comprises main control module 1, sensor assembly 2, power module 3, drive amplification circuit 4 and warning device 5, sensor assembly 2, power module 3, drive amplification circuit 4 are the peripheral circuit of main control module 1, be connected with main control module 1 respectively, the output of drive amplification circuit 4 is connected with warning device.The core of main control module 1 is single-chip microcomputer, and sensor assembly 2 consists of humidity sensor, and humidity sensor ambient humidity carries out real-time sampling.Drive amplification circuit is comprised of resistance R 1, R2 and transistor Q1, Q2, control signal that main control module sends provides base current through R1 for transistor Q1, the collector of transistor Q1 is connected with power supply by R2, the emitter of transistor Q1 is connected with the base stage of transistor Q2, the grounded emitter of Q2, the collector of Q2 is connected with warning device, and transistor Q1, Q2 form complex pipe, is used for amplifying the control signal of single-chip microcomputer output.
During concrete operations, humidity sensor carries out real-time sampling to ambient humidity, single-chip microcomputer is made response to sampled result, when ambient humidity too high, single-chip microcomputer can send a high level pulse, high level pulse provides base current by R1 for transistor Q1, transistor Q1 conducting, the transmitting of Q1 very transistor Q2 provides base current, the rapid conducting of Q2, grounded emitter due to Q2, the current collection of Q2 is low level very, make warning device bear forward voltage and have electric current to flow through, warning device is reported to the police, simultaneously due to the parallel connection of warning device two ends the light emitting diode VD1 branch road of connecting with resistance R 3, the diode VD1 that gives out light is bright.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present invention.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
