This microservice is part of the puresec ecosystem and is supposed to be an infrared detector. All movement detections will trigger a master notification. The master can decide what to do with this message (e.g. send a mail).
First of all you need a raspberry pi with installed linux distribution.
Firstly, clone repository to your rasbperry pi and change directory to the created folder.
Then you can run the ./bin/setupServer.sh script to install npm, node and other dependencies which the microservice needs to run properly. After the script is finished, try to run grunt. If all tests passing, you are ready to start with the wiring of the IR-sensor.
I'm using the HC-SR501. The VCC is connected to one of the 5V pins, the GND to one of the GND pins and the out (data) pin to GPIO4/PIN7. Later on you can configure a data pin of your choice.
Now you are ready to start the service with the following command:
node src/app.js
Following options are configurable via env properties:
| Property | Description | Default |
|---|---|---|
| MASTER_URL | URL of the master | http://localhost:3000 |
| NAME | Name of the service | IR Detector |
| DESCRIPTION | Description of the service | |
| PORT | Port of the service | 3003 |
| PIN | Pin of the data lane | 7 |
The start command with an example property:
MASTER_URL="http://url/to/master:port" [some other properties] node src/app.js
