First, let's get to know the brother who improved the home burglar alarm to become a seismograph! The improved home burglar alarm became the seismographer named Duan Yuanzhao. He is a villager living in Longxi Village, Mianyang City, Sichuan Province. Because of the frequent earthquakes here, many people are sleepy every day, every moment. They are all ready to evacuate. Mr. Duan accidentally flashed an idea in his mind one day: Can you use the home burglar alarm at home to predict the earthquake? Then he set about to study this thing, you don't even say that as long as the kungfu deep iron shovel can be ground into a needle, I did not expect Mr. Duan to use the home burglar alarm equipped with a vibration sensor detector to do the vibrometer, Mr. Duan said This small instrument can keenly remind us that there is no earthquake, and it is very practical. As long as the earthquake occurs, it will make a sound. The louder the sound, the louder the sound. This kind of home shockproof device is easy to manufacture, not only for long-term placement, but also for no problem. Electricity, no place, beautiful.
Mr. Duan's use of a home burglar alarm equipped with a vibration sensor is also very practical. Let's take a look at his working principle. The vibration sensor is mainly used to sense vibration. Once the vibration is sensed. When the detector senses the vibration, the vibration sensing detector will immediately transmit the vibration signal to the home burglar alarm alarm host through the radio wave. The alarm host receives the alarm signal from the vibration induction detector for analysis, and generates a high decibel from the siren. The alarm sound, so that once the earthquake is approaching, the vibration-sensing detector will first sense the vibration of the earthquake, and then send the vibration information to the alarm host. The alarm host will generate a high-decibel alarm sound through the siren, thus reaching the notice that the earthquake is coming. Please take countermeasures to avoid casualties caused by the earthquake
