My total parameter (83+95)x2 = 356m. i need to build motion sensor for security purpose. For each corner i need separate light and buzzer alarm. If any one try to enter my premises then alarm tiger. More you can find on attachment. In picture red area need to be motion sensitive. Each 4 corner have separate buzzer and led so security can direct easily witch corner effected. Only way to off this alarm by switch off the power of the arduino and reset when power on. Contact me in chat for more. Read project carefully before bid.
Do not bid randomly. randomly bid report to freelancer. No request for advance or partial payment grunted. After program done and test payment relies by one short. Do not over bid.
I am ready to provide you the code using ESP8266 with PIR sensor and buzzer integrated.
please send me message if you are okay with this.
recently I have done this for one client also. but its not for buzzer , it will send message to cloud and there he can check the status also.
