Can somebody help me to do a project related to wireless weather station.
The requirements are simply described as follows.

Function:
Wireless remote measurement system that communicates at 433MHz.
The purpose of the system is to measure Temperature, Relative humidity, sound.
The range is 50 to 100 meters. 1 or 6 units per base station.

Communication:
Use RF module to transmit and receive data.
Something like Nordic Semiconductor RF Chip nRF9E5, or nRF24L01 and pic18FXXX.

Power Supply:
Something that’s pretty small – about the size of a 9V battery

Data output:
low power LCD display to show the information of the weather

So i would like to obtain some advise from you all. ...would be welcomed.
