NXP Cortex-M0 LPC1100 Design Challenge

Wireless node detector

Design Photo:

Abstract
At one side we have a Wireless FM transmitter, which will send short data. This will happen in specific time, to save the battery life. From the other side we have Wireless FM receiver which will try to detect the received signal from the transmitter. We will measure the power of the received signal and display it, on PC GUI which I wrote on C# language, this is option 1 or for option 2 on LCD, where LPC1114 will show the calculated RF signal in dBm. This idea can be very useful to find your keys or generally to track any object, or human, or dog, etc in the specific distance. It is not use any GPS signal just RSSI information, so is cheap, practical and useful.

nice job

this is a good idea ! just as you said, it's cheap, practical and useful ! and your PPT is also perfect! But if u use it on track, the distance can't be too long. the anti-interference is also a problem. whether it's ZIGBEE or RF. anyway, for this contest, it's a nice job!

nice job

This FM module support up to 300m. If it will be required for longer distance I have find already move expensive and more power consumption RF devices. For interference and security I already implement the AES encryption and decryption where it support 128/192 and 256 bit. Thanks vote :)
