There is a system it is called speed dial, when button phones the no.{4,5,6} is pressed for 3-5 secs then we have to add the no so as the smoke is detected with the help of relay the no dials and the no. you saved it will dial and the phone call you
It is not necessary to use two battery in this project, also we can use a pnp type transistor. Because the digital output of MQ2 sensor is negative, If you want to know how to do this project in very simple manner Please contact me anokhramesh@gmail.com Or visit my blog anokhautomation.blogspot. com
