Cov pa phem yog teeb meem loj ntawm peb lub ntiaj teb niaj hnub no.
tab sis yuav ua li cas peb tuaj yeem saib xyuas peb cov pa phem nyob ze, tam sim no nws yooj yim heev
Yog li pib ua:
Kauj ruam 1: YUAV TSUM MATERIALS
1. NODEMCU
2. MQ7-CO-SENSOR
3. JUMPERS
4. BUZZER
5. KEV TSO CAI
6. MATCH BOX
Kauj ruam 2: Kev sib txuas
1. txuas NODEMCU -A0 tus pin rau MQ-7 SENSOR-A0 tus pin
2. txuas NODEMCU VCC tus pin rau SENSOR-VCC tus pin
3. txuas NODEMCU GND tus pin rau SENSOR = GND tus pin
4. txuas BUZZER +ve rau NODEMCU D0 tus pin
5. txuas BUZZER -ve tus pin rau NODEMCU GND tus pin
Kauj ruam 3: CODING:
1. qhib google lossis nias qhov txuas txuas yam no.
2. tsim ib tus as khauj ntawm yam khoom.
3. tsim ib daim teb tshiab ntawm qhov ntawd.
5. Qhib API KEY sib koom thiab luam cov cai
6. Muab tshuaj txhuam rau hauv cov cai arduino..
7. hloov koj tus ssid, tus password rau hauv tus lej.
