node-red-contrib-bmp180/bmp180.js

Node-Red node to get temperature, pressure and altitude from BMP180 sensor, connected by i2c. The node can run with metric units or imperial units. Based on a self-modified dbridges's bmp085 node.js script for the core.

var i2cbmp180 = require('./resources/i2cbmp180');

module.exports = function(RED) {
	
	'------------------------ bmp180 ------------------------'
	function bmp180(n) {
		RED.nodes.createNode(this, n);
		var node = this;		
		var nodeAddress = n.address;
		var nodeMode = n.mode;
		var nodeUnits = n.units;
		var nodeSeaLevel = n.sealevel;
		node.on('input', function(msg) {
			try {
				var sensor = new i2cbmp180({address: nodeAddress,mode: nodeMode, units: nodeUnits, SeaLevel: nodeSeaLevel});
				sensor.read(function (data){
					var msg = { payload: data };
					node.send(msg);
				});
			} catch (err) {
				node.error(err);
			}
		})
