The terms that you refer to are footprint/package specifications (size, shape).
Here are links to the above components on digikey:

@Olaf-Jacobs It's a straight analogue read on a single ADC pin relative to Vcc and ground of the Arduino Node.
In my case it's a pro-mini, the ADC pin in this example earlier defined as "Pressure", the result radioed in only if the ADC reading has changed. Three other binary inputs for contactors are polled every second on separate digital pins (one of which is pin 3), which uses all 4 pins available on this pro-mini due to the radio etc.
if ((!hidro&&!Hidro&&(counter2>=132))||initialise){
int incoming=analogRead(Pressure);
if (prevolume!=incoming){
prevolume=incoming;
sleep(50);
float tankvolume=(((incoming-102.3)*6.704199635)+0.5);//5psi sensor
send(msg8.set(tankvolume,0));//This is actual volume
sleep(100);
}}
I'm not clear on the rest of what you're trying to incorporate or what pin 3 (digital interrupt) has to do with it, the pressure sensor signal goes to an analogue pin to enable the voltage to be read.
I compile the example sketch fine with IDE 1.5.7.
Do you have uncommented the #define SOFTSPI in RF24_config.h for some reason (eg programming your gateway)?. If so comment it back again.
@legeantvert said:
On the same way, i dont understand how and where are stored the values inside the gateway if not used on each reception, are they stored somewhere to be able to answer them when serial request arrive?
You could bypass this on some kind of events obviously !
Actually my perl gateway is acting as the server Vera is for the arduino gateway. So from there I can trigger external URL, store data in a sqlite3 database... and so on !
