BMP085.js
Access a BMP085 temperature & barometric pressure sensor from your Raspberry Pi using Node.js.
Install
$ npm install bmp085-sensor
Usage
With no units specified, returns inHg and degree F.
var bmp085 = require('bmp085-sensor'); var sensor = bmp085({address: 0x77, mode: 3}); sensor.calibrate(function (err, data) { if(err || !data) { throw err; } console.log(data); sensor.read(function (err, data) { if(err || !data) { throw err; } // data is { pressure: 29.957463223223005, temp: 68.9 } }); }); You can also specify metric units, returning Pa and degree C:
var bmp085 = require('bmp085-sensor'); var sensor = bmp085({address: 0x77, mode: 3, units: 'metric'}); sensor.calibrate(function (err, data) { if(err || !data) { throw err; } console.log(data); sensor.read(function (err, data) { if(err || !data) { throw err; } // data is { pressure: 101435.97, temp: 20.5 } }); });
