var Thermometer = require('./index');// Example 1 - Get data in the interval
var therm1 = new Thermometer({
id: '28-000003eacfa3', // device id
interval: 600000 // interval in ms, 600000ms = 10min
}).on('data', function(data) {

// Example 2 - Get data on demand

// Example 3 - Handle errors

// To halt interval you can use halt method

Option | Type | Required | Description
-------|------|----------|------------
id | string | yes | Device id - It is the same as the file name of the sensor.
interval | int or null | no | Interval data retrieval (default: null - interval disabled).
oneWirePath | string | no | Path to 1-wire sensor file (default: '/sys/bus/w1/devices/%id%/w1_slave'). %id% will be replaced by device id.
regExp | RegExp | no | RegExp to extract temperature from sensor file (default: /t=([\-0-9]+)/).$3
Name | Params |Description |
-----|--------|------------|
init | | When init() function will be launched (fired olny once - when not inited before).
error | Error | On error on init or get data etc.
data | {} or null | Data from sensor.$3
Name | Description
-----|------------
init | Initialize thermometer (works only once, Events: init or error).
run | Initialize thermometers if not initialized and run interval if interval option is set (Events: no or error).
halt | Clear interval (Events: no).
get | Get data from sensor file (Events: data or error`).The MIT License (MIT)
