Arduino Mega and max motion sensors?

Projects General Guidance
1

I'm planning to build a model of a house and using GSM shield, motion sensors and a segment display.
I'm hoping to buy an arduino mega for this. I want to use 6 PIR motion sensors, 1GSM shield and a segment display or nokia 5110 display for home security system.
Since I haven't used a GSM or PIR motion sensor before, I don't know if it's possible to use all of this together.
Coding is not a problem, but I want to know if I will be able to use 6 sensors with all of this?

Thanks

PIR, buttons, it's all just the same for a micro :slight_smile: So yeah, should work just fine. GSM will be the hardest component in the system.

thank you very much. ah I see. So PIR is just output a low or high.

Yep. And the timing of that is specified in the datasheet of the PIR (/chip used).
