This photoelectric smoke detector can be Created a very simple and low power smoke detector alarm that is based on the RE46C190 smoke detector IC. With a minimum of external components, this circuit alarm smoke detectors are provided all the necessary features for a project type photoelectric smoke detector address.
The design incorporates a selectable gain amplifier photos for use with a pair of infrared emitter detector. A flash power internal oscillator circuit smoke detector every 10 seconds, to keep the standby current to a minimum. If smoke is sensed, the detection rate is higher for verifying an alarm condition.
