Loublet Schematic

Smoke sensitive circuit diagram

Here I am going to introduce you a very important schema.It is nothing but a smoke sensitive schema .In the market we can see there are lots of expensive smoke sensitive kits.But Im going to give you a very simple method to make a smoke detector.Here i have used a dark sensitive schema.When the smoke goes via LEDs and LDR it will generates a sound.If you want to operate another schema firstly remove the speaker and add a really for there.then you can operate your schema through that really.







Note

# Build this schema on pcb

# Dont use more than 9V

#Use Blue colour LEDs
