Raspberry pi temperature sensor that submits to Drupal

This module is an "attachment" to the blog post about the subject Drupal and IoT, found at https://orkjern.com/drupal-iot-code-part-2.

Requirements

To use this example code you need to have a ds18b20 temperature sensor, and preferrably an OS that supports the hardware modules we need to use. I use raspbian, and therefore these are the commands needed:

sudo modprobe wire
sudo modprobe w1-gpio
sudo modprobe w1-therm

If you have no idea what any of these things mean you can probably find better results by googling it than reading here. Here is one article on the subject, which also includes the needed wiring.

The code uses nodejs to sense the temperature and also send the data, so you would also need that. I am pretty sure some googling will reveal good guides on that too.

Usage

• Start by renaming the default config file to config.json. (cp default.config.json config.json)
• Then edit the config.json file to suit your needs. Specifically the API key, sensor and URLs.
• The interval specified in the config file is in minutes. So set to 1 if you want updates per minute.
• You can use the starter script included in this repo to start monitoring. To start it, run node starter.js
