Smoke Detectors Specifications | Engineering360

Photoelectric smoke detectors contain a light and a sensor that are at 90degree angles to one another. Normally, light from a light source on the left moves straight across and misses the sensor. When smoke enters the chamber, however, smoke particles scatter the light, and some amount of light hits the sensor.


Smoke Sensor Module Energia Zero

202062 · The Analog Smoke/LPG/CO Gas Sensor (MQ2) module utilizes an MQ2 as the sensitive component and has a protection resistor and an adjustable resistor on board. The MQ2 gas sensor is sensitive to LPG, ibutane, propane, methane, alcohol, Hydrogen and smoke. It could be used in gas leakage detecting equipments in family and industry.


TECHNICAL DATA MQ2 GAS SENSOR

2018615 · The sensors performance will be changed badly if sensors be sprayed polluted by alkali metals salt especially brine, or be exposed to halogen such as fluorin. Touch water Sensitivity of the sensors will be reduced when spattered or dipped in water. Freezing Do avoid icing on sensor’surface, otherwise sensor would lose sensitivity.
