Infrared thermometers yakashandura nzira yatinoyera nayo tembiricha pasina kudiwa kwekubata kwepanyama. Pakati pemhando dzakakurumbira, iyo MLX90614, sensor inozivikanwa zvakanyanya nekuda kwekugona kwayo kusanganisa nemapuratifomu akadai Arduino. Munyaya ino yakazara, isu tichaongorora zvakadzama kuti sensor iyi inoshanda sei, maitiro ayo ehunyanzvi uye mashandisirwo aangaitwe mumapurojekiti emagetsi.
El MLX90614 inzwa yakagadziridzwa neMelexis inobvumidza iwe kuyera tembiricha yezvinhu uri kure. Iyo inoshandisa musimboti weiyo infrared radiation inoburitswa nemitumbi inopisa, ichiishandura kuita masaini edhijitari anogona kududzirwa nemamicrocontrollers. Izvi zvinoita kuti ive chishandiso chinobatsira mumaindasitiri, ekurapa uye ekushandisa kumba.
Zvinonyanya kukosha zveMLX90614
Mukati, the MLX90614 Inoumbwa nesilicon chip ine micromachined membrane inoona infrared radiation. Iyi sensor inosanganisira a low noise amplifier, UN 17 bit ADC converter uye a digital chiratidzo processor (DSP) kuti uve nechokwadi chekuverenga kwakarurama. Pamusoro pezvo, inouya fekitori yakarongedzerwa, ichiva nechokwadi chechiyero chechokwadi che ± 0.5 ° C uye resolution ye 0.02 ° C.
Iyo sensor inoshanda mumhando yekushisa ye -40°C kusvika 85°C kune ambient tembiricha uye -70°C kusvika 382°C zvezvinhu. Iine maitiro maviri ekubuda: SMBus, subset yeI2C protocol, uye inobuda 10 zvishoma PWM. Uku kuchinjika kunoita kuti ive yakanaka kune akawanda maapplication.
Kuyera makona uye mhando dziripo
Chimwe chezvakatanhamara zve MLX90614 ndiko kugona kwayo kupa makona ekuyera akasiyana zvichienderana nemuenzaniso. Somuenzaniso, muenzaniso MLX90614ESF-BAA Iine kona yekuona ye 80 °, apo muenzaniso MLX90614ESF-DCI inopa kona yakamanikana ye 5 °. Izvi zvinobvumira kuti zvigadziriswe zvose kune zviyero zvakananga uye nekutarisa kwepamusoro pepamusoro.
Aya masensa anowanikwawo mumamodule akadai seaya GY-906, iyo inosanganisira magetsi anodiwa kuti afambise kubatana kwayo nemapuratifomu akadai Arduino. Kutenda kune akasanganiswa voltage regulators, aya mamodule anogona kufambiswa zvakanangana nawo 5V.
Zvikumbiro zveMLX90614
El MLX90614 Iyo inoshanda zvakasiyana-siyana uye inowana maapplication munzvimbo dzakasiyana siyana. Pakati pezvinonyanya kushandiswa ndezvekuti:
- Temperature control systems muzvivakwa kana maindasitiri maitiro.
- Medical monitoring, zvakadai seyeyero yekushisa kwemuviri isingabatanidzi.
- Kuona kukanganisa kwemafuta mumakina kana zvinhu zvemagetsi.
Nekuda kwekugona kuyera tembiricha pasina kupindira mumuviri, yakanakira nzvimbo uko kururama and the hutsanana Dzinokosha.
Kubatanidza uye kuronga neArduino
Batanidza iyo MLX90614 kune ndiro Arduino Inzira iri nyore. Iyo module inofambiswa kuburikidza nemapini GND y 5V, uye yakabatana nebhazi I2C kushandisa mapini zviwanikwa y SCL. Kubva kudivi re Arduino, mapini aya kazhinji A4 y A5 pamhando dzakaita seUno Usati watanga, ita shuwa kuti hwindo re sensor rakachena uye kuti mudziyo wasvika pakudziya kwemamiriro ekunze.
Kuronga sensor, raibhurari inoshandiswa Adafruit MLX90614, izvo zvinoita kuti zvive nyore kuverenga data. Semuenzaniso, unogona kushandisa kodhi kuratidza iyo ambient tembiricha uye chechinhu chiri pa serial monitor. Iyi nzira inowanikwa kunyange kune vanotanga muchirongwa ne Arduino.
