Nyob zoo cov neeg, hauv cov lus qhia no peb yuav kawm paub yuav ua li cas cuam tshuam DHT11 qhov ntsuas kub nrog m5stick-C (pawg tswj hwm kev txhim kho los ntawm m5stack) thiab muab tso rau ntawm cov zaub ntawm m5stick-C. So hauv qhov kev qhia no peb yuav nyeem qhov ntsuas kub, av noo & cua sov ntsuas los ntawm DHT11 thiab luam tawm ntawm m5stack m5stick-C siv Arduino IDE. Yog li ntawd peb yuav ua qhov ntsuas kub ntsuas nrog m5stick C thiab DHT11.

Kauj Ruam 1: Yam Koj Xav Tau

Rau txoj haujlwm no koj yuav xav tau cov khoom hauv qab no: 1-m5stick-C pawg thawj coj txhim kho 2- DHT11 Kub sensor3-Ob peb jumper xov hlau 4-Hom C usb cable rau Programming

Kauj Ruam 2: Teeb UP Arduino IDE rau ESP32 Boards

Nco ntsoov tias koj tau teeb tsa ESP32 cov laug cam hauv koj Arduino IDE thiab yog tias nws tsis yog li ntawd, thov ua raws li cov lus qhia hauv qab no kom ua li ntawd: ESP32 BOARDS INSTALL:

Kauj Ruam 3: Txhim Kho Tsev Qiv Ntawv

mus rau koj Arduino IDE tom qab ntawd mus rau Sketch> suav nrog Tsev Qiv Ntawv> Tswj Tsev Qiv. Tom qab txhim kho cov tsev qiv ntawv DHT no, ntaus "Adafruit Unified Sensor" hauv lub npov tshawb nrhiav thiab nqes mus. lub tsev qiv ntawv thiab teeb tsa nws thiab koj npaj txhij rau code.

Kauj Ruam 4: Kev Sib Txuas

Cov kev sib txuas tau yooj yim heev DHT11 tus pin 1 (tus lej cim tus pin): yuav txuas nrog G26 ntawm m5stick-CDHT11 tus pin 2 (VCC): yuav mus rau 3v3 tus pin ntawm m5stick-CDHT11 tus pin 3 (GND): yuav mus rau GND tus pin m5stick -C

Kauj ruam 5: Code

Luam cov cai hauv qab no los ntawm kev piav qhia thiab xa nws mus rau koj lub m5stick-C pawg tswj hwm kev txhim kho: // Piv txwv ntsuas kos rau ntau yam DHT cov av noo/ntsuas kub#suav nrog "M5stickC.h" #include "DHT.h" #define DHTPIN 26 // dab tsi tus pin peb txuas nrog rau#txhais TFT_GREY 0x5AEB // Tsis hais yam twg koj tab tom siv! #define DHTTYPE DHT11 // DHT 11 //#define DHTTYPE DHT22 // DHT 22 (AM2302) //#define DHTTYPE DHT21 // DHT 21 (AM2301) // Pib DHT sensor rau ib txwm 16mhz ArduinoDHT dht (DHTPIN, DHTTYPE); tsis muaj teeb tsa teeb tsa () {M5.begin (); M5.

Kauj Ruam 6: Tso Tawm

Tom qab xa cov cai koj tuaj yeem pom qhov ntsuas kub, av noo & ntsuas cua sov ntawm cov zaub raws li qhov tso tawm.
