We are working on application which will use external sensors , we need someone to do the design and explanation which hardware we should use and why.

Case :

10+ sensors , data need to be sent/received from/to/sensors , Ideally on ZigBee solution but any other solution I can consider - is all about the cost of the hardware - must be as low as possible like CC2530 for ZigBee.

All sensors need to be battery powered and communicate with app in android within 20+ metres range.

What we need you to do is to explain what hardware we should use for above project ( ready made modules avaialble on the market).

AS we need approx 1 hour consultancy - we offer approx 20 USD for this task.
