LEIDS yog dab tsi?

LEIDS yog IOT sensor uas yog nyob ib puag ncig ESP8266. Qhov ntsuas no ua rau siv lub rooj tsav xwm no, lub latching me me, hloov lub reed, thiab qee cov hlau nplaum los tsim lub qhov rooj sensor uas yuav xa kev ceeb toom rau koj thaum koj lub qhov rooj qhib thiab kaw. Qhov ntsuas no tuaj yeem txuas rau koj li MQTT server, IFTTT, lossis ntau lwm yam txheej txheem uas txhawb nqa ESP8266. Cov lus qhia no yuav siv IFTTT kom yooj yim tsim lub ntsuas uas yuav xa ntawv ceeb toom rau koj lub xov tooj ntawm tes tsis hais koj nyob qhov twg. Lub ntsuas kuj tseem tuaj yeem teeb tsa kom tso cai rau ntau qhov ceeb toom los ntawm qhov rooj sib cais, lub thawv xa ntawv, lub qhov cub thiab lwm yam uas muaj qhib/kaw lossis qhib/tawm ntawm lub cev. Qhov txiaj ntsig ntawm LEIDS yog nws siv lub zog me me thiab tsuas yog siv lub zog thaum lub qhov rooj qhib, tom qab ntawd thaum lub qhov rooj raug kaw nws xa lus ceeb toom rau koj lub qhov rooj raug kaw thiab tawm mus. Qhov no zoo dua li pw tsaug zog qhov qauv vim nws tsis siv lub zog yog tias lub qhov rooj tsis qhib.

Kauj Ruam 1: Cov khoom siv

Cov npe hauv qab no qhia cov cuab yeej thiab ntu uas kuv siv rau txoj haujlwm no. Lub sensor tuaj yeem rov tsim dua los siv qhov sib txawv thiab saib/ua haujlwm sib txawv thiab tsuas yog siv cov ntsiab lus zoo sib xws.

Kauj Ruam 2: Lub Latching Circuit ទន់ - Kho vajtse

Lub voj voos me me uas kuv siv yog kev hloov pauv ntawm cov txheej txheem uas kuv pom hauv online. Kuv tsis yog tus kws tshaj lij thiab kuv ntseeg tias muaj txoj hauv kev zoo dua los tsim qhov Circuit Court no tab sis rau kuv lub hom phiaj qhov Circuit no ua haujlwm!

Txoj hauv kev nws ua haujlwm yog tias thaum lub reed switched raug kaw los ntawm qhov chaw sib nqus nws tso cai rau tam sim no rau NPN transistor. NPN transistor ua rau thaj chaw PNP mosfet uas tso cai rau tam sim no ntws mus rau ESP8266. ESP8266 lub zog siv, siv ib qho ntawm nws tus pin los khaws PNP mosfet hauv av uas txuas ntxiv rau lub zog ESP8266. Tom qab ntawd thaum ESP8266 ua tiav nrog nws cov haujlwm, nws teeb tsa tus pin rau LOW uas cuam tshuam NPN transistor thiab kaw lub qhov rooj ntawm PNP mosfet.

Los ntawm kev siv hluav taws xob xws li qhov no ESP8266 tuaj yeem siv tau los ntawm kev hloov pauv, thiab tom qab ntawd tuaj yeem ua kom nws tus kheej tawm ntawm qhov teeb liab. Qhov no tso cai rau kev kos duab tsis muaj qhov tam sim no thaum lub kaw lus kaw/tawm.

Kauj Ruam 3: ESP8266 - Kho vajtse

ESP8266 uas kuv tab tom siv yuav xa cov lus ceeb toom thaum lub qhov rooj (lossis lwm yam) qhib thiab tom qab ntawd yuav tos lub qhov rooj kaw kom xa cov lus kaw thiab kaw nws tus kheej. ESP8266 yuav muab hluav taws xob los ntawm lub latch muag muag thiab yuav siv ib tus pin los nyeem qhov hloov pauv reed thiab lwm tus pin kom nws tus kheej ua haujlwm thiab tom qab ntawd tig nws tus kheej tawm. Kuv xaiv siv ESP-01s vim nws yog daim ntawv me. ESP yuav xa lub vev xaib thov ceeb toom rau peb thaum lub ntsuas ntsuas tau hloov mus rau "qhib" thiab "kaw". Txoj hauv kev yooj yim tshaj plaws uas kuv pom yog siv IFTTT thiab Google Sheets. Qhov no tau piav qhia hauv cov theem hauv qab no.
