I'm doing my final project and still in confuse on what kind of sensor to use to detect GSM signal. Anybody knows?
A quick google search led me to numerous sensors, some of which are discussed on these forums.
What is the relation to Arduino?
this is what i read. When using with an Arduino board you have to connect the sensor output to an analog input. The measured sensor voltage is equivalent to the received radio signal strength. The 5 Volt to power the sensor can be obtained from the Arduino 5V terminal.
Where did you read that?
So you have a sensor already otherwise you would not have this info?
Take a look on this

i still dont understand a lot about sensor need to use on how to detect gsm signal and how it involves the arduino on this case.
