I am looking for someone to design a Remote Sensing Unit and a Central Hub. The Hub will be indoor and Remote Unit Outdoor. Communication possibly will be through radio communication in range that's legal for private users. Requirements are mentioned in the .pdf uploaded. I am looking for 2 circuit diagrams, source code of software and any other details to facilitate manufacturing. I expect the logic to be fully tested and proof of the same provided. If satisfied, I may further require a working prototype(s), apps etc.

I have expereince in RF desing, for 1-2km range you need to go for sub GHz modules. I have experience with chipcon product line with front end RF amplifiers. Running byy 1.5V battery depend on the frequency which the system transmits data.

Hi, I am an Electrical Engineering and works as an Emebedded design engineer in a good firm. I have made such systems that you are demanding, I have made Automatic Gas sensing and Alert system. In which remote sensors are attached at each gas points they sense the safe level after sensing they are wirelessly linked to the central unit. and then with the android app. I have used variety of radio transceivers like nrf24L01, xbee s1 , nrf51822 ble v4.0 modules. So your project is just a modification or may be extension . Please contact me as soon as possible for further discussion. I will offer you high quality work in less rates. Looking forward to work with you.

I am a low-price labor and now I am doing the relative work in my field as a electrical engineering student,thus I think I can be a good worker for this project.
