sensorjs

This module handles all about sensor with powerful and familiar techs. In other words this sensorjs is not only sensor driver module but also framework like express.

And it's working on linux boards such as the BeagleBone or Raspberry Pi.

Here is the guide to create your own driver. Here is currently available sensor driver list.

Installation

$ npm install sensorjs 

sensor.js URL scheme

sensorjs://[{gateway}]/{sensor_network}[:{bus_id}]/{address}/{sensor_model}/{sensor_id}{&query_strings}

• example
  • sensorjs:///i2c:1/33/dht33/22-000003a7f590
  • sensorjs:///gpio/22/singleled/r222&name=sensingLed
  • sensorjs:///ble/000A3A58F310/proximity/0A3A58F310-1

Example

var connect = require('sensorjs'),
   sensorDriver = connect.sensor;

var app = connect().
  use(connect.filter({$between: [-50, 50]})).  // filter: passing between -50 and 50
  use(connect.average(20 /*duration*/)).  // reduce: values to an average every 20 sec.
  use(function (data, next) {  // custom middleware
    if (Math.max.apply(null, data.queue) < data.value) {
      console.log('new record', data.value);
    } 
    next();
  }).
  use(connect.queue(100)).                   // buffering max # of 100.
  use('/w1/*/ds18b20', function (data, next) {
    if (data.value > 20) {
      console.log('getting hot:', data.value);
    }
    next();
  }).
  use('/gpio/*/dht11', function (data, next) {
    if (data.value < 30) {
      console.log('getting dry:', data.value);
    }
    next();
  });
  // transport(mqtt, localStorage, websocket and etc)
  //use(connect.websocket('http://yourhost.com', 'temperature/{id}'/*topic*/));
