Dzimwe nguva unoda kuziva kupisa kwechinhu chiri kure. Inogona kuva imba yekusvuta, barbecue, kana kunyange imba yetsuro. Ichi chirongwa kubva chinogona kunge chiri chauri kutsvaga.
Kure kudzora nyama, asi kwete kutaura. Iyo ine MAX31855 thermocouple amplifier yakagadzirirwa kushandiswa neanozivikanwa K-mhando thermocouples. Inobatana neTexas Instruments CC1312 microcontroller inotumira zviyero zvekupisa pamusoro pe802.15.4 protocol pakavakirwa matekinoroji akadai seZigbee uye Thread. Inokwanisa kutumira mameseji eredhiyo pamakiromita marefu pasina kushandisa simba rakawanda, izvo zvinoita kuti zvikwanise kushandisa CR2023 coin cell bhatiri muchirongwa ichi. Yakasanganiswa neiyo firmware inoisa sisitimu kurara kana pasina kuyerwa kuri kutorwa, inotarisira kuti chirongwa ichi chishande kweanosvika makore akati wandei pabhatiri rimwe.
Mameseji anounganidzwa uye anoiswa muGrafana marongero, kwaanogona kurongeka zviri nyore. Kuti uwedzere kubatsirwa, chero tembiricha iri kunze kweiyo seti renji inokonzeresa yambiro ye smartphone kuburikidza neIFTTT.
Kunyatsotarisa tembiricha ndiyo kiyi yekubika chikafu chinonaka nevanoputa, saka chirongwa ichi chinofanira kushanda nemazvo. Kune avo vanoda kutarisa kure kure tembiricha yavo nekunetseka kushoma, izvi zvinofanirwa kushanda futi!
Munyaya yakaipisisa, iyo thermocouple pachayo yaizoshandiswa kubhadharisa iyo capacitor uye simba iyo transmitter ...
Sekusvika kwaunoenda, nzvimbo yangu yekutangira inogona kunge iri kuverenga 1968 RCA bepa rekutsvagisa reNASA kuti vaone chinofanira kushandiswa mukati meRTG* (simba rinoshandiswa mu1977 Voyager space probe raifanira kunge rakaonekwa pano).
Ramba uchifunga kuti kana iwe uchida kushandisa thermocouple kuyera chimwe chinhu, kune yakanyanya kurongeka ** iwe unotoda kwete (kana zvishoma kwazvo) ikozvino kuyerera.
Nekudaro, kana iwe uchida kuti junction ibudise simba, saka iwe unofanirwa kudhirowa yakawanda ikozvino sezvaunokwanisa uchigadzirisa iyo yakanyanya simba kuti ive shoma pane iyo yakanyanya voltage (iyo voltage inodonha pamharadzano ichawedzera kuderedzwa, uye kudonha kuyambuka. tambo yekubatanidza, sezvo vane kushorwa, iyo yakawanda ikozvino yaunodhonza, uye kushorwa kunoshandukawo nekushisa - iyo yakakwirira ikozvino, yakakwirira tembiricha).
Ndiri kushamisika kana zvichiita kugadzira inokurumidza uye yakasviba 2D mita pandinoyera ikozvino uye voltage uye kuyera tembiricha. Ipapo iyo yekutarisa-kumusoro tafura inongoshandiswa kune yazvino uye voltage kuyerwa, kwete yechizvarwa modhi, static modhi, uye tembiricha kuyerwa maitiro.
Nekushandisa webhusaiti yedu nemasevhisi, unobvuma pachena kuiswa kwekuita kwedu, kushanda uye kushambadza makuki.dzidza zvimwe
