Hi there,
I'm about to embark on a project involving an UNO board, PIR sensor, speaker, GSM shield and micropohone.
The idea is, when someone passes the PIR sensor, the GSM shield is triggered to send me a text. Once I get the message I can phone call the device if I wish to do so. When I call the device i'm hoping my voice will be able to be heard from the device via a speaker of some sort. And if someone is near the device they can speak to me through a microphone.
First of all, is this feasible? I am fairly new to Arduino and have completed a basic Pololu 3pi robotic project two years ago. I am aware there is plenty of code available online for the PIR sensor code. However not sure how to apply it and adapt it to trigger the GSM and how to wire and adapt the microphones and speakers.
I have bought none of the components so far, posting here to ensure I have the right things on my shopping list. This includes:
- Arduino UNO board, (I saw the sintron version on amazon, it's a lot cheaper, anyone know if this is ok to purchase?)
- PIR sensor X1
- SIM900 GSM shield
- breadboard - not sure which type, do I need an Arduino prototyping shield also? Also should this be a large size breadboard?
- Speaker - what ohm speaker? What voltage/wattage needed? Do I need resistors or amplifiers? Read a few things online about 8 ohm speakers but I need a loud volume?
- microphone module..?
- Jumper wires - do I need Male to Male; Female to Female or Female to Male; or all three?
- Battery - should this be 9V? do I need more than one?
- Battery clip
Is there anything you'd recommend adding to that list?
Forgot to add, I need the system to work without being connected to a laptop, i.e. on its own? Also can I make a phone call FROM my phone TO the device? Or must the GSM shield telephone me?
Any advice is welcomed, thank you in advance.
