Project Description

In this project, you will build the sensor Analog output voltage and when the smoke reaches a certain level, it will make sound a buzzer and a red LED will turn on.

When the output voltage is below that level, a green LED will be on.

Working Mechanism

Pin Connections:

  • Connect sensor A0 pin to Arduino A5 pin
  • Connect sensor GND pin to GND
  • Connect sensor Vcc pin to Vcc
  • Connect buzzer +ve to Arduino pin 10
  • Connect buzzer -Ve to GND through 221ohm resistor
  • Connect +ve pin of Red led to Arduino pin 12
  • Connect -ve pin of red led to GND through 221ohm resistor
  • Connect +ve pin of Green led to Arduino pin 11
  • Connect -ve pin of Green led to GND through 221ohm resistor
