Sense the status of your washing machine with a TI CC2650 Sensor Tag and the MEAN Stack.

Sense your washingmachine!

Sense the status of your washing machine with a TI CC2650 Sensor Tag and the MEAN Stack. Display the remaining time until your washing machine is done. If the washing-machine is done, a SMS will be sent to your phone.

Resources

• Raspberry Pi 3 Model B
• Texas Instruments CC2650 Sensor Tag

Requirements

• Node.js lib for the TI Sensor Tag https://github.com/sandeepmistry/node-sensortag
• MEAN STACK:
  • Node.js
  • Express
  • MongoDB
• npm install in sense-washingmachine/
• bower install in sense-washingmachine/public // todo add .package file for bower
• Twilio account https://twilio.github.io/twilio-node/

High-Level Overview

• The TI CC2650 Sensor Tag has an accelerometer sensor which is attached to the washing machine
• Raspberry Pi 3.0
  • Node server
  • MongoDB
  • AngularJS
• Every x seconds accelerometer data is requested from the node server at the Pi
  • For each measurement a new entry of accelerometer is saved in the MongoDB
  • If there are significant divergences in the acc measurements, the status of the washing machine is updated to running; if there are no significant divergences the status of the washing machine is updated to false
  • If the status of the washing machine turns from running to not running, a SMS is sent to the users phone
• At the website the $scope is updated every x seconds and so the status of the washing machines are updated
• When the washing machine is done, an SMS is sent to your mobile device via Twilio

Start

1. Make a free Twilio account here https://www.twilio.com/try-twilio
2. Open the alert.js file and change the Account SID and Auth Token in the line var client = new twilio.RestClient(YOUR ACCOUNT SID HERE, YOUR AUTH TOKEN HERE);
3. In the client.sms.messages.create section, Change "to:" to "to: YOUR PHONE NUMBER HERE" and "from:" to "from: YOUR TWILIO PHONE NUMBER HERE
4. find out IP-address of your Raspberry Pi
5. in public/app/app.js change the options.api.base_url to the current ip address
6. start mongodb with “sudo mongod” in a terminal on the Raspberry Pi

• If an error like “unclean shutdown detected occurs” execute cmd “sudo mongod --repair”

7. start to sense data from the sensor: “sudo node startSensing.js”
8. start the webserver: “sudo node server.js”
9. the website can be viewed in the browser at “http://ip_address:4567
