Electric car battery cabin smoke alarm.

In recent years, more and more electric vehicles have been used, but fire accidents caused by improper use of electric vehicles have also increased. Moreover, charging the electric car is the main cause of the fire. Its harm is mainly manifested in two aspects: one is the high temperature in the fire, but the smoke from the fire. Can reap degrees Celsius temperature of combustion process, including the toxic smoke more terrorist, electric fire after 30 seconds can produce poisonous gas, if someone is trapped may be inhaled carbon monoxide, hydrogen sulfide and in a short period of time will produce the symptom such as dizziness, nausea and vomiting, and often delirious, action inconvenience, find a safe exit harder! Small make up remind you must install the smoke alarm to avoid traction electric vehicle battery storehouse fire damage, the following is the armoured WeiXin professional research and development of JTY GD - smoke alarm DG312 electric vehicle battery storehouse in detail:
The photoelectric sensor with special structure design combines with the reliable MCU, which can effectively detect the smoke in the initial stage of fire and the generation of the smoke. When smoke into the detector, make the light scattering, accept element feel light intensity, the received light intensity and smoke concentration have certain linear relationship, the detector parameters on site constantly gathering, analysis, and judgment, when confirm the intensity of light field data reaches the threshold, the starter relay output. When the smoke in the environment returns to normal, the detector automatically returns to normal working condition. Self-check: under normal condition, the detector carries out internal function test and relay output according to the self-test test button.
