5. CONNECTING CABLE
6. MATCH BOX
Step 2: CONNECTION
1. connect NODEMCU -A0 pin to MQ-7 SENSOR-A0 pin
2.connect NODEMCU VCC pin to SENSOR-VCC pin
3.connect NODEMCU GND pin to SENSOR=GND pin
4. connect BUZZER +ve to NODEMCU D0 pin
5. connect BUZZER -ve pin to NODEMCU GND pin
Step 3: CODING:
1. open google or press this link thingspeak.
2.create an account on thingspeak.
3. create a new field on that.
5.Open API KEY sharing and copy the code
