Smoke Alarm With High Sensitivity

This small gadgets will alert and warn people stay far away from danger field when it detected smoke.this product named photoelectric detector (hereinafter called detector) detects the smoke by a couple of infra-red diodes. the principle of detecting is granule in the smoke can reflect infra red light. infra-red diodes are placed in the special chamber. the chamber can shield external light, but don’t affect the smoke into it.while have no smoke, the diode can receive very weak infra red light. when the smoke entering the the chamber, diode can receive more and more light, when the smoke attains the certain density, the detector can give out alarm signal. in order to reduce the interference and lower power consumption, the emitting circuit adopts the pulse signal.the detector adopts the special structure design and asic, has the dust proof, moth proof and anti outside light interference feature etc. the detector is suitable for detect the smoke in house, shop, hotel, restaurant, office building, school, bank, library, computer house and storehouse etc.
