Description
Technical field
The utility model belongs to the technology of instrument and meter field, particularly relates to a kind of atmosphere quality monitoring device.
Background technology
At present, air pollutants such as formaldehyde, hydrocarbon, alcohol, carbon monoxide, cigarette, benzene bottoms etc. extensively are familiar with for people the harm that human body health is caused.Because air quality is the term of a wide range, when judging air quality, many factors such as temperature, humidity, air-flow, residence, and the air position of using etc. all can exert an influence to it, therefore the air quality of monitoring, the especially workplace of air quality is monitored at present still difficult problem in real time.
The utility model utilizes the susceptibility of tin oxide semiconductor gas sensor to multiple low concentration air pollutants, for the real-time monitoring of air quality provides a kind of effective way.This sensor is a kind of porous beads gas sensor, and surface area is big, can freely absorb the gas molecule of semiconductor surface.Can produce electron transfer between gas molecule and the oxygen molecule that absorbed, this makes sizable rising that gas concentration produces slight change and causes electric conductivity.This variation produce quite fast (in seconds) and full bi-directional.Because this element is a semiconductor gas sensor, does not have moving parts, therefore definitely can work many years.This sensor can mainly comprise gases such as hydrogen, hydrocarbon, alcohol, carbon monoxide, cigarette, benzene bottoms to the difference induction of multiple gases.
Summary of the invention
The technical matters of the utility model for existing in the solution known technology, and a kind of atmosphere quality monitoring device is provided.
The purpose of this utility model provides a kind of simple in structure, and is cheap, have safe and reliable, directly perceived, the air quality real-time monitoring device of lower-price characteristic.
The utility model is taked following technical scheme:
A kind of atmosphere quality monitoring device, comprise sensor, wiring board, display device, power supply and shell is characterized in that: the wiring board of sensor connection processing detection signal, and wiring board connects display device, display device is controlled switching by the high-low level signal of output, and display device is fixed on the shell.
The utility model also adopts following technical measures:
Described atmosphere quality monitoring device is characterized in: sensor is a tin oxide resistance-type metal oxide semiconductor sensor.
Described atmosphere quality monitoring device is characterized in: sensor is fixed on the shell.
Described atmosphere quality monitoring device is characterized in: display device is light emitting diode or liquid crystal display.
Described atmosphere quality monitoring device is characterized in: power supply is USB power supply or chemical storage batteries.
Advantage that the utlity model has and good effect:
Atmosphere quality monitoring device has adopted the utility model brand-new technology scheme, and the processing of sensor signal via line plate is controlled the switching of display device by the high-low level signal of output, and sensor and display device are fixed on the shell.The utlity model has 1) intuitive is strong: adopt the pilot lamp of three kinds of different colours to show airborne pollution level; 2) low-power consumption: select the USB joint for use, directly be inserted on the computer and get final product; 3) highly sensitive; 4) life-span is long; 5) simple in structure, advantage such as price is low.
