Abstract: Laser water distribution is one of the sensors we need to control mechatronic modules. Based on the information coming from it through this sensor, it performs the control function of raising and lowering the gates in the water distribution mechatronic modules to a certain distance and includes the tasks of always showing the status of the gates.
Keywords: water distribution system, mechatronic module, laser sensor, information technology, contact scheme
Introduction. The modern theory of water distribution in mechatronic systems[1-12] is mainly based on the continuous supply of water to their consumers and is based on the equations[13-21] of the continuity and quantity of water flow in main channels and the continuity of processes in space and time. In many mechatronic systems, in the presence or absence of water, the mode of supplying water to consumers is carried out discretely[22-31] in time, therefore, the parameters of the water flow in such systems depend on the discreteness of the operation of the structures.
Currently, with the development of the theory of optimal control of mechatronic systems with different characteristics, it became possible to create a special theory of optimal distribution of water in mechatronic systems under conditions of discrete water supply to consumers. Modern digital technologies[15-25] and digital methods (splines, generalized functions, digital algorithms, databases and graphic representations of data) allow creating special systems for mathematical modeling and optimal distribution of water in mechatronic systems based on the development of control systems.
Functions and equations should be taken into account when developing mathematical models of optimal water distribution, necessary optimality conditions for selected criteria of water distribution between water consumers and other components of the theory of optimal water distribution in mechatronic systems.
Main part: After we connect the laser to a constant 9-36V power supply, the laser will light up. When the laser is turned on, the infrared light measures the distance to the obstacle. It sends the determined distance to USB via RS485 signal in
the decimal system. The USB takes the data and sends the data to the personal computer. We can read the information coming from it through the program, through which information is visible to us in the desktop program on the computer.

Conclusion
Laser water distribution is one of the sensors that we need to control the mechatronic modules using the information coming from it through the sensor. In the water distribution mechatronic modules, it includes the tasks of lifting the gates to a certain distance and always displaying the position of the gates and performing the function of controlling the lowering.
