M2M alarm system
In this recipe, we are going to apply what we have learned so far about M2M communications to build a simple alarm system that will be completely based on cloud M2M interactions. There will be one or many motion sensors that will send alarm triggers to a central station composed of an LED and a small buzzer.
There are two parts in this project: the motion sensor module, and the central base module with an LED and a sound buzzer.
This is the list of the required components for this recipe, not counting the Arduino MKR1000 boards and the breadboards and wires:
- PIR motion sensor (https://www.sparkfun.com/products/13285)
- LED (https://www.sparkfun.com/products/9590)
- 330 Ohm resistor (https://www.sparkfun.com/products/8377
