Hello, I need to control some relays (5) from the main station to the final station (800 meters). It is possible by wire but I prefer wireless communication because is cheaper. I need to send the information by USB (laptop) then, receive an Arduino or a microcontroller; turn on some leds and put available some switch. After that, send the information (800 meters) and this information will be receive other arduino or microcontroller, turn on/off the relays and re-send a feedback to check the succesfull process. Also, I need to receive information every 30 seconds from 20 temperature sensors (LM35). I need only the schematic and the files of PCB and hexadecimal program. Thanks!

Hi, I am an electrical engineer and works an Embedded system designer . I have 5 years of experience with wireless communication module. I have done the similar projects like wireless irrigation system , water quality management using wireless GPRS, I have used nrf24L01 which is the cheapest wireless communication module and it will cover your 800 meter range. I have also used xbee ,zigbee, wizzimotes, CC2540 wireless modules that are energy efficient and have high range, All these modules can be integrated with the arduino. So this project is really easy for me to do as i have made the similar projects. I am new here so i have no testimonials but if you work with me you will always do, I will offer you quality work on less rates. Looking forward to work with you..
