Smock ditector hand made on GPB (General Purpose Board)

Introduction

• This home smoke detector circuit warns the user against fire accidents.
  It relies on the smoke that is produced in the event of a fire and passes between a bulb and an sensor, the amount of light falling on the sensor decreases. This type of circuit is called optical smoke detector. Do not use it as a home smoke detector it’s jus for electronic projects.

   Using this photoelectric smoke detector circuit can be designed a very simple and low power smoke detector alarm project that is based on the MQ 2 smoke detector . With minimal external components, this smoke detectors alarm circuit will provide all the required features for a photoelectric smoke detector type electronic project.

   The design incorporates a gain-selectable photo amplifier for use with an infrared emitter detector pair. An internal oscillator strobes power to the smoke detection circuitry every 10 seconds, to keep the standby current to a minimum. If smoke is sensed, the detection rate is increased to verify an Alarm condition.
