Is it good or bad that bats always fly into the room at midnight?

Bats often fly into the room at midnight, which indicates what will happen? A bat flies into the house, which means there is food it likes to eat. It is estimated that there are many mosquitoes in your house and the surrounding ecological environment is good. Otherwise, bats wouldn't come here, and it doesn't have any special significance. It's just here looking for food. As we know, bats are almost blind in vision and perceive their surroundings through ultrasonic detection. It doesn't know whose home this is.

We humans have been learning from the creatures and animals in nature. One of the most commonly used ultra-ranging and reversing radars is actually learning from bats. They can judge the objects around them by emitting ultrasonic waves and then returning waves. They can know whether the things around them are still or moving without looking, and they can also capture flying insects very accurately. It is admirable to solve your own food and clothing problem and not hit obstacles, which is better than using your eyes.

Now almost every family has a car, and parking and reversing has always been a long-standing problem, especially for novice drivers. The current reversing radar can help our driver friends judge the distance very well. In fact, this distance is also used. By sending out super-life, we begin to calculate the time, then multiply the time by the speed and divide it by 2 to get the final distance. The reason is simple, but it is still complicated to realize. We should be fault-tolerant, conduct multiple tests, and then filter out anomalies.

Although bats are ugly, they are very helpful to us. We not only learned a lot from them, but also helped us eat a lot of pests, which not only saved pesticides, but also avoided pesticide poisoning, so we should not hurt them or get in close contact with them, because bats have a lot of bacteria, so it is best not to let them enter our homes. At night, close the doors and windows this morning to prevent flying insects from coming in.
