Nyob Zoo Cov Menyuam, Hauv Cov Lus Qhia no kuv yuav piav qhia yuav ua li cas kom yooj yim huab cua chaw kom paub qhov kub thiab av noo siv DHT11 sensor thiab Arduino, cov ntaub ntawv nkag siab yuav tshwm ntawm LCD Zaub. Ua ntej pib qhov kev qhia no koj yuav tsum paub qee cov ntaub ntawv hais txog DHT11 sensor.
Yog xav paub ntxiv mus ntsib Electronics Projects Hub
Cia peb pib….
Kauj Ruam 1: Qhov Yuav Tsum Tau
DHT11
16 × 2 LCD Zaub
Arduino Ib
Txiv neej rau Poj Niam Jumper Xov - 8
Kauj Ruam 2: 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 3: Txuas DHT11 Nrog Arduino
Yog tias koj tab tom siv 4 tus pin DHT11 Kev Sib Txuas yog raws li hauv qab no
DHT11 |
Arduino UAS |
| Vcc | 3.3v ua |
| Tawm | PIN4 (Digital) |
| GND | GND |
| NC | -- |
Txuas 10K Ohm resistor ntawm Vcc thiab Out Pin ntawm DHT11.
Yog tias koj siv 3 tus pin DHT11 Kev Sib Txuas yog raws li hauv qab no

Arduino UAS |
| Vcc | 3.3v ua |
| Tawm | PIN4 (Digital) |
| GND | GND |
Kauj Ruam 4: Txuas I2C LCD Zaub rau Arduino
Kuv twb tau qhia lawm yuav ua li cas txuas I2C LCD zaub rau Arduino
Koj tuaj yeem tshawb xyuas ntawm no
I2C LCD Arduino
GND GND
VCC 5 VV
SDA AW 4
SWB A5
Kauj ruam 5: Code
Koj yuav tsum suav nrog dht11 thiab I2C LCD tsev qiv ntawv. Koj tuaj yeem rub tawm hauv qab no.
