Mumapurojekiti ako ungangoda kuve nemidziyo chaiyo yekutarisa mamiriro emhepo enzvimbo uye kuona kuvepo kweanokuvadza. Iye sensor MQ-135 Ndizvo zvawanga uchitsvaga, zvichipa kuvimbika uye kwakanyatso onekwa kwemagasi akasiyana anokuvadza hutano.
Pano unogona kudzidza nezvazvo maitiro uye kushandiswas yeMQ-135 sensor, ichiratidza kugona kwayo kuona magasi akadai seammonia, doro, benzene uye utsi, uye iwe uchadzidza mashandisiro ayo neArduino…
Chii chinonzi MQ-135 sensor?
El MQ-135 module inzwa indium-doped tin oxide semiconductor (In2O3-SnO2) ine magetsi ekufambisa anosiyana zvichienderana nekuwanda kwemagasi munzvimbo yayo. Iyi shanduko mu conductivity inoshandura mukusiyana kwemagetsi ekupikisa kwe sensor, iyo inogona kuyerwa uye inoshandiswa kugadzirisa kusangana kwemagasi aripo.
Pakati pemagasi anogona kuonekwa mumhepo CO2, Doro, Nitrogen Oxide (NOx), Carbon Monoxide (CO), Ammonia (NH3), Sulfide, Benzene (C6H6), utsi nemamwe magasi zvinokuvadza kuhutano. Ramba uchifunga kuti hazvibviri kuyera huwandu hwegasi rimwe nerimwe, zvinongokubatsira kuti uone hutano hwemhepo kuburikidza nekutarisa kuvapo kwemhando iyi yemagasi.
Uyezve, unofanira kuziva izvozvo sensitivity inogona kusiyana zvichienderana negasi rakayerwa, semuenzaniso:
- Ammonia (NH3): 10ppm-300ppm
- Benzene: 10ppm-1000ppm
- Doro: 10ppm-300ppm
Nezvekushanda kwayo, iyo MQ-135 sensor inobva pakubatana pakati pemagasi aripo mumhepo uye nzvimbo inonzwisisika ye sensor, inoumbwa netin oxide doped ne indium, sezvandamboratidza. Kana gasi rasangana ne sensor surface, Mamorekuru egasi anoita nemaatomu eokisijeni adsorbed pamusoro, achiburitsa maerekitironi nekugadzirisa mafambiro emagetsi echinhu chacho..
La Hukuru hwekuchinja kwemagetsi conductivity kunoenderana nekusangana kwegasi uye hukama hwayo netin oxide yakashongedzwa ne indium. Magasi akadai seammonia, doro, benzene uye utsi, pakati pevamwe, ane hukama hwepamusoro hwechinhu ichi, icho chinoshandura kuva shanduko huru mumagetsi emagetsi e sensor.
MQ-135 Sensor Applications
Iyo MQ-135 sensor inowana huwandu hwakasiyana hwekushandisa muzvikamu zvakasiyana, kusanganisira:
- Kutarisisa kwezvakatipoteredza, kuona mhando yemhepo munzvimbo yakasikwa, semuenzaniso.
- Kuchengetedzeka kwemaindasitiri kuona kubuda kwegasi kunogona kuve nengozi kuvashandi.
- Kumba otomatiki, kudzora mhando yemhepo mudzimba dzakangwara uye zvivakwa, kunyanya izvo zviri mumaguta makuru kana padyo nemafekitori.
- Automation, yekuona magasi mune otomatiki maindasitiri maitiro uye kugadzira chiito kana gasi raonekwa.
- Tsvagiridzo yesainzi, yezvidzidzo zvemhando yemhepo uye kuvapo kwemagasi anokuvadza munzvimbo dzakasiyana siyana.
Inofanira kuwedzerwa kuti sensor iyi haisi kungosiyana-siyana chete, asiwo yakachipa, ine kunzwisiswa kwakanyanya kwemagasi akasiyana-siyana, iri nyore kushandisa, yakavimbika uye inomira yakashata mamiriro ezvakatipoteredza. Nekudaro, ichokwadi zvakare kuti ine painogumira, sezvo isingasarudze kune rimwe gasi chete, inogona kuve nehanya nekuchinja kwezvakatipoteredza senge humidity kana tembiricha, chiratidzo chayo hachiwanzo mutsara kana ichinge yaona gasi, saka ndizvo. zvakaoma kuziva huwandu huripo, uye nguva yekupindura kwayo haisi iyo inokurumidza, saka kushanduka kamwe kamwe muhuwandu hwegasi kunogona kutora nguva kuratidzwa ...
Nezve magasi akaonekwa neMQ-135
Kana zvakadaro magasi akaonekwaZvinofanira kutaurwa kuti MQ-135 inonzwisisa kune yakanaka yakawanda yemagasi anokuvadza. Sezvandambotaura, pakati pavo pane:
- Carbon dioxide (CO2): Iyi gasi, kana yakawanikwa yakawanda, inogona kusimudza acidity yeropa munzvimbo dzisina oxygen-yakashata inogona kukonzera kutemwa nemusoro, dzungu, kurara, kusvotwa, kuvhiringidzika uye kunetseka kufema. Kana kuisa pfungwa uye kuratidzwa kwakanyanya, zvinogona kukonzera kunyange mamwe matambudziko makuru uye kunyange rufu. Izvi zvinojairika mumidziyo yewaini panguva yekuvirisa, uko huwandu hukuru hwegasi iri hunogadzirwa uye hwakatokonzera rufu ("rufu runotapira") kuvanhu vakati wandei ...
- Doro (EtOH): Aya mhute edoro anogona zvakare kukonzera muchetura, matambudziko emapapu, kushandura sisitimu yetsinga, kukonzera kurutsa, dzungu, nezvimwe.
- Nitrogen oxides (NOx): mune iyi imwe nyaya isu tine gasi reasidhi, iro rinogona kukonzera kutsamwisa kumaziso, ganda, nzira yekufema, kunetseka kufema, kurwadziwa muchipfuva, kukuvara kwemapapu, kuwedzera zvirwere zvekufema, nezvimwe.
- Carbon monoxide (CO): Sezvakaita diokisi, iyi imwe gasi inetso kuhutano, ichiburitsa zviratidzo zvakada kufanana, asi inogona kutotungamira kurufu muzviitiko zvakanyanya zvechepfu, saka zvakakosha kudzora kuvepo kwayo.
- Amoniya (NH3): Iri rimwe gasi rinogona kukonzera kutsamwisa kumaziso uye turakiti rekufema, kukosora, zvirwere zvisingaperi zvekufema, kukuvara kwemapapu, nezvimwe.
- Sulfidi (S): Sulfides inogonawo kukonzera matambudziko akafanana neammonia.
- Benzene (C6H6): Iyi ndiyo imwe yemagasi ane ngozi, anogona kukonzera kupfava mhedzisiro senge kutemwa nemusoro, dzungu, kusvotwa, kushatirwa kwematishu, asiwo mamwe matambudziko akareba senge matambudziko ekuzvara, kenza senge leukemia, nezvimwe.
- Kusvuta nevamwe: Mamwe magasi anoonekwa neMQ-135 anogonawo kukonzera matambudziko ekufema, kunyanya kune avo vane COPD, asthma, nezvimwewo, pamwe nekushatirwa kwemaziso, kufema kwekufema, kukosora, kurwadziwa kwechipfuva, kukuvara kwemapapu, kenza. mapapu nekuda kwezvikamu zviripo, nezvimwe.
MQ-135 pamwe neArduino
Chokutanga pane zvose, zvakakosha kuziva nzira batanidza iyo MQ-135 module kune mamaboard Arduino UNO kuitira kuti ishande nemazvo uye isu tinogona kutanga kuyedza kodhi yedu. Kuti uite izvi, zviri nyore kwazvo, iwe unongofanirwa kutarisa pinout yemodule yako uye ubatanidze neiyi nzira:
- GND yemodule ichave yakabatana neGND yeArduino board.
- VCC yemodule ichave yakabatana ne5V yeArduino.
- DOUT yeMQ-135 inogona kubatana neArduino analog yekupinda, semuenzaniso, pini A0.
Kune rimwe divi, iwe zvakare unofanirwa kudhawunirodha iyo MQ-135 raibhurari yeArduino IDE kubva pane iyi link. Kana yangoiswa, tinogona kutanga nayo test code, iyo inogona kufanana neinotevera:
#include "MQ135.h"
#define ANALOGPIN A0
#define RZERO 206.85
MQ135 gasSensor = MQ135(ANALOGPIN);
void setup()
{
Serial.begin(9600);
float rzero = gasSensor.getRZero();
delay(3000);
Serial.print("MQ135 RZERO Valor de calibración: ");
Serial.println(rzero);
}
void loop() {
float ppm = gasSensor.getPPM();
delay(1000);
digitalWrite(13,HIGH);
Serial.print("Valores de CO2 en ppm: ");
Serial.println(ppm);
}
