Application circuit diagram of MQ-2 smoke sensor.

In today's society, the awareness of environmental protection is deeply rooted among the people. Nowadays, many products are sold to smoking customers under the banner of environmental protection. Indeed, environmental protection is in great demand for most people who pursue a taste of life. Environmentally friendly green products have a relatively large sales volume in the market.

, so developing green products has become the goal pursued by scientific and technological personnel.

There are relatively few finished ashtrays on the market that can remove smoke, and almost none can automatically activate by induction.

Therefore, our team designed this defogger ashtray that can automatically sense. This product uses the popular MQ-2 sensor with good sensitivity on the market. Therefore, the sensitivity of this product is quite good, and we have adopted several layers of filtration.

, which decomposes harmful substances in smoke to a great extent and is the most ideal product to make indoor air environmentally friendly.

Design concept? In homes and offices, because the male owner smokes too much, the room is often filled with fog. Especially in winter, when the indoor ventilation is not good, it will cause damage to the health of the people indoors.

Traditional ashtrays can only hold ash but cannot absorb smoke that is harmful to the human body and the environment. This device uses a smoke sensor. When the smoke spreads, and the smoke sensor senses the smoke, the relay switches to NO, the fan starts working, and the motor rotates.

The fan generates suction to suck the smoke into the filter housing filled with activated carbon and negative ions, expelling fresh and clean gas, which greatly improves the indoor environment and has current significance for environmental protection.
