Buenas Tardes Realmente necesitaría mas de información con respecto a tus necesidades, pero el colocar 10 sensores de temperatura LM35 a distancia de 430 metros, donde necesitas transmitir la información a esa distancia y mostrar la data en un aplicación en Visual Basic, con el PIC18f2550 y el diseño del circuito electrónico y el layout de la PCB. Todo es to es posible pero hay cuestiones de interferencia y demás que se tendría que hablar para que funcione correctamente y por ello seria bueno que me contactes si te es de utilidad lo que te digo, gracias Datos a entregar para el proyecto: - Diseño del circuito electrónico en eagle 7.4. - Diseño del PCB en eagle 7.4. - Vista de la parte superior de la PCB en 3D sin componentes. - Vista de la parte inferior de la PCB en 3D sin componentes. - BOM - Lista de componentes. - Gerber - Datos para manufactura del producto. - Codigo en C de CCS, comentado linea a linea. - Simulación del sistema en Proteus 8 de ser posible. - Aplicación en Visual Basic o C#, para visualizar los datos obtenidos de los sensores. - La comunicación del hardware con la aplicación puede ser por medio de comunicación serial o USB, al momento de conversar me comentara su necesidad. Lo que necesites me preguntas sin problema alguno. Nota: El costo puede variar en mas o menos cantidad, dependiendo de los problemas traiga la distancia a la que necesitas transmitir pero eso ya se conocerá luego de conversar y conocer bien sus necesidades.

Hi, Dear! I have developed several boards used with 18F2550 microcontroller. Specially, I have been developed several communication device and have been made Visual C++ program to display the information form the sensors in real time via the LM35, DS18B20 temperature sensors. Your project success is my happiness. I would not disappoint you if you select my service. I am looking for your reply. Best Regards! Luo.

I will provide you the solution and will provide support after the system has been put in use. This is my first bid at Freelancer. I know there is not much that I'm doing to convince you of my capabilities, but I'm sure you will be far beyond satisfied with the solution that I will provide. I need a few more inputs from you to start of with. There needs to be a close communication on the project being worked so that I can develop the solution as per your expectation.
