00:00YetNovice. Channel for the whole family.
00:30Who are these fixies? It's a big, big secret.
00:39Who are these fixies? It's a big, big secret.
00:47Sensor
00:52We need to replace this part with a new one.
00:55Evgeny Evgenievich, let's run to the warehouse.
00:58It's not convenient for you.
01:00And you continue to repair.
01:02I agree. Just remember her name.
01:05K-12-71. I'll remember.
01:21It's always Liza in time.
01:24We'll wait for her to leave.
01:26What else? We'll go behind her back.
01:29Y, where is our part?
01:31Here.
01:35Are you ready?
01:36Ready.
01:38Let's go.
01:41Sensor
01:52Here you are, Evgeny Evgenievich.
01:55Why does the door open and close by itself?
02:00The thing is, Liza, that the door is now automatic.
02:05I put a motion sensor on it yesterday.
02:11A motion sensor is an electronic eye
02:15that monitors everything that moves.
02:18Have you seen how in shops and airports
02:21doors open by themselves in front of people?
02:24This is thanks to a motion sensor.
02:27It notices when a person approaches the door
02:30and sends a signal to the electric motor.
02:33The motor opens the door,
02:35and then automatically closes it
02:38when a person passes through it.
02:46Incredible person.
02:49But not neat.
02:53Automatic door?
02:55Why didn't it open when we went upstairs?
02:58You are too small for it.
03:01And the detail is big.
03:03The sensor reacts to it.
03:05And what to do?
03:07Let's trick it.
03:09Let's go along the wall.
03:11Let's stay close to the wall.
03:20This door is too automatic.
03:23And these details again.
03:26Didn't I clean them?
03:32The sensor still sees us.
03:34Let's break it.
03:36Why break it?
03:38You can just turn it off temporarily.
03:45Sensors help people in different situations.
03:49For example, motion sensors
03:52notice when someone walks
03:55and can open the door or turn on the light.
03:58Rain sensors are installed on cars.
04:01If it starts to rain or snow,
04:04they turn on the windshield wipers.
04:07There are also sensors that react to lighting.
04:11In the evening, when it gets dark,
04:14they automatically turn on the street lights.
04:17And in the morning, when it gets light,
04:20they are turned off.
04:22The smoke sensor senses when there is smoke in the room.
04:26Such a sensor can turn on the fire alarm
04:29and even the fire extinguishing system.
04:35All right!
04:37Turned it off!
04:39Then let's go!
04:48Evgeny Evgenievich, the task is completed!
04:51Well done!
04:53No, not well done.
04:55This is K-71-12.
04:57Yes.
04:59And I need K-12-71.
05:02Petrik!
05:04You said you remembered!
05:06I remembered.
05:08And then I forgot.
05:10Oh, you stupid head!
05:13Okay, let's run again.
05:16No, I'd better do it myself.
05:21And I forgot to warn you
05:24that we turned off the sensor.
05:27And now the door does not automatically open.
05:30Evgeny Evgenievich, who am I?
05:46Sorry, Evgeny Evgenievich.
06:00The End
