Qee zaum koj yuav tsum paub qhov kub ntawm ib yam dab tsi los ntawm qhov deb. Nws tuaj yeem yog lub tsev haus luam yeeb, lub barbecue, lossis txawm tias lub tsev luav. Qhov project no los ntawm tej zaum yuav yog qhov koj tab tom nrhiav.
Tswj cov nqaij ntawm qhov chaw deb, tab sis tsis txhob tham. Nws muaj lub MAX31855 thermocouple amplifier uas tsim los siv nrog cov thermocouples K-type nrov. Nws txuas rau Texas Instruments CC1312 microcontroller uas xa cov kev ntsuas thermal hla 802.15.4 protocol uas cov thev naus laus zis xws li Zigbee thiab Thread yog raws li. Nws muaj peev xwm xa cov lus xov tooj cua hla kev deb yam tsis siv hluav taws xob ntau, uas ua rau nws muaj peev xwm siv lub roj teeb CR2023 npib hauv qhov project no. Ua ke nrog firmware uas ua rau lub kaw lus pw tsaug zog thaum tsis muaj kev ntsuas, xav tias qhov project yuav khiav tau txog li ntau xyoo ntawm ib lub roj teeb.
Cov lus tau sau thiab sau cia rau hauv Grafana qhov chaw, qhov chaw uas lawv tuaj yeem yooj yim kos duab. Rau qhov txiaj ntsig ntxiv, txhua qhov kub sab nraum qhov ntau yam teeb tsa yuav ua rau muaj kev ceeb toom ntawm lub xov tooj ntse ntawm IFTTT.
Kev saib xyuas qhov kub thiab txias yog qhov tseem ceeb rau kev ua noj cov zaub mov qab nrog cov neeg haus luam yeeb, yog li qhov project no yuav tsum ua haujlwm zoo. Rau cov neeg uas xav saib xyuas lawv qhov kub thiab txias nrog qhov teeb meem tsawg kawg nkaus, qhov no yuav tsum ua haujlwm thiab!
Hauv qhov xwm txheej phem tshaj plaws, lub thermocouple nws tus kheej yuav raug siv los them lub capacitor thiab muab lub zog rau lub transmitter ...
Raws li koj xav, kuv qhov pib yuav yog nyeem daim ntawv tshawb fawb RCA xyoo 1968 rau NASA kom pom tias yuav tsum siv dab tsi hauv RTG * (lub zog siv hauv xyoo 1977 Voyager space probe yuav tsum tau tshwm sim ntawm no).
Nco ntsoov tias yog koj xav siv lub thermocouple los ntsuas qee yam, rau qhov raug siab ** koj xav kom tsis muaj (lossis me me) tam sim no ntws.
Txawm li cas los xij, yog tias koj xav kom qhov sib txuas tsim hluav taws xob, ces koj yuav tsum rub ntau li ntau tau tam sim no thaum ua kom lub zog siab tshaj plaws tsawg dua qhov hluav taws xob siab tshaj plaws (qhov hluav taws xob poob hla qhov sib txuas yuav raug txo qis ntxiv, thiab qhov poob hla cov xov hlau txuas, vim tias lawv muaj kev tiv thaiv, qhov hluav taws xob ntau dua koj rub, thiab qhov kev tiv thaiv kuj hloov pauv nrog qhov kub thiab txias - qhov hluav taws xob siab dua, qhov kub thiab txias siab dua).
Kuv xav paub seb puas muaj peev xwm tsim tau ib lub 'meter' 2D uas ceev thiab qias neeg uas kuv ntsuas tam sim no thiab voltage thiab ntsuas kub. Tom qab ntawd lub rooj saib xyuas tsuas yog siv rau kev ntsuas tam sim no thiab voltage, tsis yog rau hom tiam, hom static, thiab hom ntsuas kub.
Thaum koj siv peb lub vas sab thiab cov kev pabcuam, koj pom zoo rau qhov chaw uas peb muab cov ncuav qab zib ua haujlwm tau zoo, ua haujlwm tau zoo thiab tshaj tawm. kawm ntxiv
