Abstract

The utility model relates to a storage room humidity detection system which comprises a humidity sensitive resistor used for detecting air humidity, and a processing unit for comparing and amplifying a signal detected by the humidity sensitive resistor, wherein the processing unit transmits a processed result to a controller; the controller is connected with a buzzer and a GSM-SM modem; a timer used for timing when the buzzer is at a buzzing state is connected between the buzzer and the controller. According to the storage room humidity detection system provided by the utility model, the humidity in a storage room can be monitored in real time, a manager in the storage room is prompted to timely take corresponding measures, the humidity of the storage room is adjusted, and articles are well saved.

Description

Dust humidity detection system between storing

Technical field

The utility model relates to dust humidity detection system between a kind of storing.

Background technology

In order better object being stored, between storing, need to remain in certain humidity, and humidity between existing storing mainly to be felt by human body, so just can produce certain error, thereby brought certain impact to the storage of object; And the personnel between management storing can not be known the humidity between storing in time, and do corresponding remedial measures.

Utility model content

For the problems referred to above, the purpose of this utility model is to provide dust humidity detection system between a kind of storing, and it can carry out Real-Time Monitoring to the humidity between storing, and reminds managing between storing to make in time corresponding measure, adjust the humidity between storing, to better preserve object.

The utility model is achieved through the following technical solutions:

Dust humidity detection system between storing, comprise the hygristor for detection of humidity in air, and the processing unit that compares and enlarges of the signal that hygristor is detected, described processing unit sends result after treatment to a controller, described controller connects a hummer, note cat, between described hummer and controller, be connected one for timing hummer the timer in buzzing state.

Described controller is the single-chip microcomputer of model at89s52.

The beneficial effects of the utility model are: hygristor detects in real time to the humidity between storing, the result detecting passes to controller after relatively amplifying by the computing of processing unit, processing unit is exactly that humidity information for hygristor is detected is calculated more accurately, avoids occurring too large error; In the time of in the scope of not setting in the humidity information value of controller acquisition, controller just can drive hummer in buzzing state, can remind like this related personnel to make corresponding measure; Simultaneously, timer carries out timing to hummer in buzzing state, when reaching certain hour, during unmanned elimination hummer buzzing state, controller sends the short breath of humidity by starting note cat to related personnel, the object that reaches prompting with this, the personnel between management storing that solved like this go out, and inconvenience between the management storing bringing.The utility model can carry out Real-Time Monitoring to the humidity between storing, and reminds managing between storing to make in time corresponding measure, adjusts the humidity between storing, to better preserve object.

Accompanying drawing explanation

Fig. 1 is control principle schematic diagram of the present utility model.

Embodiment

With reference to Fig. 1, dust humidity detection system between storing, comprise the hygristor 1 for detection of humidity in air, and the processing unit 2 that compares and enlarges of the signal that hygristor is detected, processing unit sends result after treatment to a controller 3, when the humidity between storing changes, the resistance of hygristor is also being followed and is being changed, make to be transported to the LM324 amplifier in-phase end of processing unit different with the voltage pressure reduction of reverse end mutually, and after processing unit comparison and amplifying, send controller to, the processing unit here comprises lm324 operational amplifier; Controller connects a hummer 4, note cat 5, between hummer and controller, be connected one for timing hummer the timer 6 in buzzing state.Controller is the single-chip microcomputer of model at89s52.Above-mentioned hummer, note cat and timer are and on market, buy part.
