AVT2822 B

The presented device was designed for use in a caravan to control the water level in the tank. Of course, the system can find many other applications, e.g. as a simple distance meter. The range of the measuring track is over 50 cm.
The device consists of two parts. The first one, the main one, is a complete measuring path - its task is to measure the distance with the help of ultrasounds and to calculate the results accordingly. These functions are implemented by a system designed based on the ATTiny series microprocessor.
The second part is a small display - two digits. The readout field made in this way is connected to the main module of the cable section. This makes it easier to install the display in the cabin of the vehicle.

The device is especially recommended in distance measurement systems and caravan lovers
