AVT5370 A +

The presented system facilitates entering a car in a car in a situation when the car has no reversing sensors or they work incorrectly due to, for example, reflections from various small items collected in the garage, which is often a storehouse of such 'men's treasures'. Sonar automatically activates itself after motion detection and deactivates, in the case of a long absence of changes in its surroundings. It has three thresholds for distance signaling and sound signaling.

Recommendations: ultrasonic sonar, easy to build and launch, facilitates entering and parking the car inside the garage. Shows (using three colors of diodes) the distance ranges in which the vehicle is located. Additionally, it signals by sounding the approach below the given critical distance.

Selected parameters:

• 12 Vdc power supply max. 80 mA
• ATmega8 microcontroller
• software in Bascom AVR language
• signaling of three distances by means of LED diodes and sound signal
• PCB dimensions: 80-68 mm

The set includes a printed circuit board, programmed layout and documentation.
