DIY, sekutaura kunoita Wikipedia, yagara iri subculture. Muchinyorwa chino ndinoda kutaura nezve yangu DIY purojekiti yediki isina waya yakawanda-yekubata sensor, uye ichi chichava mupiro wangu mudiki kune iyi subculture.
Nyaya yepurojekiti iyi yakatanga nemuviri, inoratidzika kunge yakapusa, asi ndiwo matangiro akaita chirongwa ichi. Mhosva yacho yakatengwa paAliexpress webhusaiti, zvinofanirwa kucherechedzwa kuti mhando yepurasitiki yekukanda nyaya iyi yakanakisa. Mushure mekunyorerana pfupi nemutengesi, mufananidzo wakatumirwa netsamba uye chirongwa chakatanga.
Iyo yekudhirowa pachayo yakanga isina kuyerwa zvakanyanya uye hafu yezviyero zvemiganhu, cutouts uye tekinoroji maburi eramangwana rakadhindwa redunhu bhodhi raifanira kuitwa uchishandisa caliper. Mushure mekugamuchira zviyero zvese zvemukati zvenyaya, zvakava pachena kuti redhiyo chip yaizofanira "kufambiswa" zvakananga padhidhi redunhu bhodhi, sezvo kureba kubva kumusoro kweakadhindwa redunhu bhodhi kusvika mukati meiyo nyaya yaive. 1.8 mm, uye hurefu hudiki hweavhareji yeredhiyo module inowanzoita 2 mm (isina skrini).
Iyo nRF52 SoC muQFN48 package yakasarudzirwa sensor. Muchiitiko ichi mune nRF52 akatevedzana, Nordic ine sarudzo nhatu: nRF52810, nRF52811 (itsva), nRF52832. Chip parameters: 64 MHz Cortex-M4, 2.4 GHz transceiver, 512/256 KB Flash, 64/32 KB RAM ye nRF52832 uye 192 KB Flash, 24 KB RAM ye nRF52810, nRF52811, multi-protocol chips, kutsigira Bluetooth Low Energy mesh, ESB, ANT, uye nRF52811, kuwedzera kune zviri pamusoro, zvakare ine Zigbee uye Thread, pamwe neBluetooth Direction Finding.
Ndakafunga kugadzira iyo sensor pachayo yakawanda-sensory kuitira kuti ishandiswe kune akasiyana mabasa. Nechikonzero ichi, marongerwo eiyo chip aifanira kuitwa senge compact sezvinobvira, tichifunga nezve iyo mipimo midiki yezvikamu haifanirwe kunge iri pasi pe0603 kuitira kuti mudziyo unogona kutengeswa nemaoko. Mushure mekunge chip yaiswa pabhodhi, ndakatanga kusarudza masensa. Zvinhu zvikuru zvandaitarisa pakusarudza zvaive zviyero zveimba ye sensor uye kukwanisa kutengesa sensor kumba neine shoma seti yemidziyo (soldering iron uye hair dryer).
Masensa anotevera akasarudzirwa sensor: SHT20, SHt21, Si7020, Si7021, HTU21D (tembiricha uye humidity sensor), ese ma sensors aya ane imba imwechete uye mapini akafanana, HDC2080 (tembiricha uye humidity sensor) inewo imba yakafanana neye. isati yanyorwa, asi ine imwezve yekukanganisa inobuda, simba rakawanda, BME280 (tembiricha, humidity uye pressure sensor), LMT01 (temperature sensor), TMP117 (high precision tembiricha sensor), kushanda nesimba kwesimba, kukanganisa kubuda, kuseta tembiricha yepamusoro uye yakaderera. miganhu, LIS2DW12(accelerometer) yakakwira simba rekushandisa, imwe yeakanakisa muchikamu chayo kana LIS2DH12.
Zvakare, mune yekutanga vhezheni ye sensor, pane chinja chetsanga mune rondedzero, asi mudzokororo dzakazotevera haina kuverengerwa, sezvo 1.6 cm reed switch sensor ine girobhu yegirazi yakanga isina nzvimbo yakakwana, uye ndakapatsanura akati wandei. ma sensors akadaro pakuisa bhodhi rakapedzwa mukesi, zvakare nekuda kweskweya Rudzi rwekesi uye hurefu hwayo hudiki hauna kunyatsoenderana nemudziyo semagineti kuvhura uye kuvhara sensor.
Kuwedzera kune ma sensors, kune maviri ma LED pane sensor, imwe yacho iRGB iri pazasi pe sensor. Mabhatani maviri eSMD, imwe yakabatana kuti igadzirise, yechipiri "mushandisi" yekushandisa mamwe ma sensor oparesheni mamiriro. Iyo sensor body ine zvikamu zvitatu: muviri mukuru, yemukati inopinza ine buri rinobata bhatiri uye yakanamirwa kumuviri mukuru nemakona mana, uye yepasi chivharo chinopinda mumakomba ari mukati memukati. Kune zvakare mapini mana eanalogi, 2 mapini edhijitari uye mamwe mapini maviri anogona kunge ari NFC antenna kana mapini edhijitari, SWD port.
Iyo RGB LED uye mabhatani anoiswa paPCB board nenzira yekuti anogona kuwanikwa nyore kana chivharo chepasi chabviswa kuburikidza nemaburi ari mukati memukati, ayo akagadzirirwa snap chivharo chekumashure panzvimbo.
Chishandiso ichi chakapfuura nekudzokororwa kuviri, zvakare kare, panzvimbo yeTMP117 sensor, MAX44009 light sensor yakaiswa, iyo yakazotsiviwa neyekushisa sensor, masensa ese ane muviri mumwechete, asi mapini akasiyana pamakumbo, anogona ive pasina kuti yakatsiviwa, pamwe yakakodzera kudzoka.
Ikozvino ndine 4 michina yakadai inoshanda kumba, maviri acho ari tembiricha uye humidity sensors ane Si7021 sensors (imwe panRF52832, yechipiri panRF52811), imwe inzwa yekuvhundutsa inoshandiswa paLIS2DW12 accelerometer (nRF52810) uye tembiricha yekudzora sensor. paLMT01 sensor (nRF52810).
Iyo isina waya sensor inomhanya paCR2032 bhatiri, kudyiwa mukurara ndeye 1.8 ΞΌA yenRF52810, nRF52811 uye 3.7 ΞΌA yenRF52832. Kushandiswa mu data transfer mode 8mA.
Ini ndinofunga tsananguro yeprotocol yakashandiswa uye kuvandudzwa kwesoftware yeiyi sensor kune akasiyana mashandisiro mamiriro ari kupfuura chiyero chechinyorwa ichi.
Muedzo wekushanda kwe sensor ine smart home system inogona kuoneka muvhidhiyo pfupi pazasi.
Iyo purojekiti yeiyi sensor yakavhurika, unogona kuwana zvese zvigadzirwa pane purojekiti pane yangu .
Kana iwe uchifarira zvese zvine chekuita neDIY, iwe uri mugadziri weDIY kana unongoda kutanga, unofarira kushandisa DIY zvishandiso, ndinokoka munhu wese anofarira .
Kune wese anoda kugadzira michina, tanga kuvaka otomatiki yeimba yavo, ini ndinokurudzira kujairana neiyo-nyore-kudzidza-Mysensors protocol - telegraph chat.
Uye kune avo vari kutsvaga mhinduro dzakanyatsokura dzekumba otomatiki, ini ndinokukoka iwe ku telegraph chat . ()
Ndatenda nekutarisisa kwenyu, zvese zvakanaka!
