Nyob Zoo Cov Menyuam, Hauv Daim vis dis aus no kuv yuav Qhia Koj yuav ua li cas kom yooj yim huab cua kom paub qhov sov thiab av noo siv DHT11 sensor

Khoom siv

Cov npe khoom: -Arduino UNO -16 × 2 LCD MODULE -Jumper Cable -DHT 11 -

Kauj Ruam 1: Txog DHT11 Sensor

DHT11 yog qhov ntsuas cua thiab qhov kub thiab txias. Nws tuaj yeem siv los ua cov ntsuas cua nrog rau qhov ntsuas kub. Koj tuaj yeem pom dht11 sensor ntawm 2 hom hauv khw. Ib qho yog nrog 4 tus pin thiab lwm tus yog nrog 3 tus pin. Hauv 3 tus pin dht11 sensor twb tau 10k Ohm resistor tau ntxiv rau hauv tus qauv. Qhov ua haujlwm ntawm qhov ntsuas no yog 3.3 V. Qhov tso tawm ntawm lub ntsuas no yog digital.

Kauj Ruam 2: Txuas DHT11 Nrog Arduino

Kauj Ruam 3: I2C LCD Zaub

Qhov no yog 16x2 LCD zaub screen nrog I2C interface. Nws muaj peev xwm tso saib 16x2 tus cim ntawm 2 kab, cim dawb ntawm xiav keeb kwm yav dhau.

Feem ntau, Arduino LCD cov phiaj xwm phiaj xwm yuav tawm ntawm cov peev txheej yooj yim, tshwj xeeb nrog Arduino Uno. Thiab nws kuj tseem nyuaj heev nrog cov xaim hlau txuas thiab txuas. Qhov I2C 16x2 Arduino LCD Screen no siv I2C kev sib txuas lus sib tham. Nws txhais tau tias nws tsuas xav tau 4 tus pin rau lub vijtsam LCD: VCC, GND, SDA, SCL. Nws yuav txuag tsawg kawg 4 digital / analog pins ntawm Arduino. Txhua tus txuas yog tus qauv XH2.54 (Hom Breadboard). Koj tuaj yeem txuas nrog jumper xaim ncaj qha.

Kauj Ruam 7: PCB PROTOTYPE MANUFACTURERS

Yog tias koj tsis ua koj tus PCBs koj tus kheej, koj ua rau lawv nyob qhov twg? Tus kheej, Kuv tsis muaj qhov chaw thiab lub siab tawv (tsis yog txuj ci) los ua lawv tus kheej. Rau SF, kuv tig mus rau Util-Pocket, vim kuv pom hais tias qhov zoo yog qhov zoo rau tus nqi. Rau DF (nrog cov qhov hlau), Kuv tau sim ntau lub tuam txhab, txhua tus ua haujlwm tau zoo, tab sis nws raug nqi ntau heev. Lub sijhawm no kuv hais rau kuv tus kheej ntawm no. Kuv muaj 3 lub voj voog ua, suav tag nrho qhov nruab nrab ntawm 49 cm2. Thaum kuv pom tias qhov tsawg kawg kom muaj nuj nqis yog 5 PCBs, Kuv txuas ntxiv kuv xaj tsis xav paub, tsuas yog pom nqe lus thiab thaum kuv pom tus nqi nug, Kuv tso qhov kev txiav txim.
