About: ONE from INFINITY

The pollution is major problem of our today's world.

but how we can monitor our pollution near by, now its very easy

SO LET'S START:

2. MQ7-CO-SENSOR

3. JUMPERS

4. BUZZER

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
