Hello.
I bought a smoke detector on Alliexpress a few days ago for exactly this:
3.1.18. Do not send links that will cease to be active after some time. This will make the discussion meaningless.
[retrofood]
The problem is that when I blow cigarette smoke at him, he does not squeal and does not react.
my question should it be like this?
is it damaged?

Video of me blowing cigarette smoke on him:
[movie: 58bdabc32f] https://filmy.elektroda.pl/35_1507801115.mp4 [/ movie: 58bdabc32f]

You can't see it like that on the camera, but there was a cloud of smoke in the real world.

How can I read the manual if it was not included in the set?

There is no "TEST" button there?

In my opinion, this sensor is not working.
Have you checked the power?

If it squeaks, I think so

Try with the chimney smoke, this is what this detector was made for. There may not be enough carbon monoxide in cigarette smoke.

It should beep and the indicator light should flash or be solid. Try to turn it on, wait a minute and smoke. If it doesn't help - advertise.
As a side note: what to expect for four dollars. Do you value your safety enough?
Very good autonomous detectors are produced by, for example, Polon-Alfa, Kidde, Yotogi, and those available in household appliances stores, electrical stores, Castoramas, etc., also work properly, where there is no problem with a possible complaint.

Stop raving - it's a photoelectric detector - it reacts to smoke particles, not chemical products of combustion.

The indicator lamp flashes periodically (Can be seen in the recording)
it shines continuously when I click it to test it

Added after 2 [minutes]:

If this is something I can take a picture of the sensor from the inside
maybe you will say that it is used for something else?

Detector, like a detector ... Smoke chamber (a bit small), electronics, squeegee ... Standard.

I'm testing now differently, I poured some oil and a piece of food onto the bottom of the oven.
it burns at 250 degrees, opened a cloud of smoke.
sensor what?
er ......
smoke?
nothing even reacted

Added after 10 [minutes]:

I got a reply from the producer.
The sensor is a smoke detector.
however he starts squeaking when he self (ignites)
....
After this message from the seller, I don't understand anything O_o
is it supposed to work that it lights up and then squeaks?

Added after 38 [minutes]:

IT'S WORKED!
I lit 4 cards, held over it for 2 minutes and it squealed!

The photoelectric detector reacts to dense smoke, and even dust, so they should be periodically "blown through" with compressed air. The signaling diode increases the frequency of blinks to a constant light depending on the operation of the photoelement. Continuous light means detector activation, depending on the equipment it may squeal and / or close / open the relay contacts.

Above or below the sensor? Maybe this sensor only reacts to temperature rise ...?
Take that junk out and buy something decent and proven!

Greetings.

However, the smoke from the chimney did it!
On the other hand, it is questionable to use this particular detector when it needs such a "dose" of smoke to operate.

I will say this once it worked.
Now, in order for it to squeal again, I had to burn the cardboard with it, it made a noise like locomotives and after 2 minutes he realized that he needed to squeal.
if I recorded it, it would probably be a nice Meme

My smoke detector starts working when a slice of bread in a toaster burns, although it's hanging on the other side of the kitchen. It would be a pity for me to waste a dozen zlotys ...

Topic summary

The discussion revolves around a smoke detector purchased from Alliexpress that fails to respond to cigarette smoke. The user questions whether this lack of response is normal or indicative of a malfunction. Responses suggest checking the power and the presence of a "TEST" button, with some users recommending testing with chimney smoke instead, as cigarette smoke may not contain sufficient carbon monoxide. The user later reports that the detector only activates when exposed to dense smoke, such as from burning cardboard, raising concerns about its reliability. Several users express skepticism about the detector's effectiveness, suggesting that it may require a significant amount of smoke to trigger an alarm. Brands like Polon-Alfa, Kidde, and Yotogi are mentioned as alternatives for more reliable smoke detectors.
