Budget: 7000 UAH Deadline: 7 days
Hello!
I have extensive experience in programming microcontrollers (ESP, Arduino, ATMEL) and working with various sensors/modules. I have successfully completed orders on this topic multiple times.
As I see your project: there is a phototransistor for each laser, tuned to the wavelength of the laser, which captures the modulation of a signal of a certain frequency. Only through a deviation from this frequency after a certain short period of time (to prevent false alarms) will the alarm be triggered. That is, if an intruder even tries to shine a laser on the phototransistor, they will not be able to deceive the system. If necessary, I will select the required sensors and create a connection diagram considering the distance.
I will write a reliable optimized firmware that will work out of the box.
The price indicated is approximate for basic functionality. We can form an exact budget after clarifying your desired circuitry and organization of work.
I would be very happy to further discuss the project!!
