Description
Technical field
The utility model relates to a kind of environment supervision instrument, relates in particular to a kind of humidity alarm.
Background technology
Humidity has three kinds of citation forms, i.e. vapour pressure, relative humidity, dew point humidity.Vapour pressure (being once called absolute humidity) represents the pressure of water in air vapour part, and one of decimal, take hundred handkerchiefs (hPa) as unit, is got by unit; Relative humidity with actual vapor in air press with temperature at that time under the percentage of ratio of saturation vapour pressure represent, round numbers; Dew point humidity is the temperature while representing cooling reaching capacity under water in air vapour content and the constant condition of air pressure, unit with degree Celsius (℃) represent, get one of decimal.While being furnished with hygrometer, can also measure continuous recording and the minimum relative humidity of relative humidity.
Air humidity has important purposes in many aspects, and in aerology, meteorology and climatology, it is mainly an importance value in theory, and effect in practical application is smaller.Relation in the humidity of air medically and between breathing is very tight.Under certain humidity, oxygen ratio is easier to enter blood by alveolar.Common people feel the most comfortable under the relative humidity of 45-55%.Relative humidity overheated and in unaired room is generally lower, and this is may be to skin bad and mucous membrane is had to spread effect.The too high perspiration functions that affects people's regulate body temperature of humidity, it is sultry that people can feel.Generally speaking people at high temperature but low humidity in the situation that (such as desert) better than the sensation of (such as rainforest) in the situation that the not too high but humidity of temperature is very high.When anaesthetizing by breathing, the humidity of anesthetic gases is very crucial.The anesthetic gases medically using is generally deposited in anhydrous situation, if do not add in use the words of humidity, can in people's lung, cause evaporation and dehydration.
So need humidity to carry out monitoring at every moment in a lot of occasions and environment, to guarantee that humidity is in the scope of suitable people living, humidity measuring method comprises wet and dry bulb mensuration, dew point psychrometric method, utilizes material geometrical variations mensuration, coulometric hygrometer, optics shape hygrometer, gas chromatography, chemical substance electrical characteristics method, ionic crystal condensation hygrometer etc., the humidity alarm of prior art exists circuit structure more complicated, the problem that the degree of accuracy of warning is not high.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem a kind of humidity alarm.
In order to achieve the above object, the utility model has adopted following technical scheme:
A kind of humidity alarm, comprise KC-100 type digital operation amplifying circuit, the first resistance, the second resistance, electric capacity, potentiometer, triode, loudspeaker, power supply and temperature sensor, the positive pole of described power supply respectively with the first end of described electric capacity, the first input end of described loudspeaker, the first end of described temperature sensor is connected with the second leads ends of described KC-100 type digital operation amplifying circuit, the first leads ends of described KC-100 type digital operation amplifying circuit is connected with the first end of the first end of described the second resistance and the second end of described temperature sensor and described the second resistance respectively, the second end of described the second resistance is connected with the first end of described potentiometer, the second end of described potentiometer respectively with the negative pole of described power supply, the sliding end of described potentiometer, ground connection after the collector of described triode is connected with the 4th leads ends of described KC-100 type digital operation amplifying circuit, the 3rd leads ends of described KC-100 type digital operation amplifying circuit is connected with the first end of described the first resistance, the second end of described the first resistance is connected with the base stage of described triode, the emitter of described triode is connected with the second input end of described loudspeaker.
The beneficial effects of the utility model are:
The utility model is a kind of humidity alarm, has solved circuit structure more complicated that the humidity alarm of prior art exists and the not high problem of degree of accuracy of warning, has the value of promoting the use of.
