Introduction.

Moving backwards, the driver is guided by rear-view mirrors. Mirrors do not give full visibility, and it is also impossible to accurately determine the distance to the barrier. The driver cannot see a certain area of ​ ​ space. People, animals can get into this zone. The proposed device eliminates this situation. Along with the acoustic locator, there are many such devices, but because of their high cost, they are not always available to motorists. This problem is solved by acoustic location. Compared to analog devices, acoustic emitters have a significant price difference with distance sensors.

Due to its simplicity and cheapness compared to similar ones, the device offered for design can be widely used.
