Run this example from the command line with:
node eg/altimeter-BMP180.js
const { Altimeter, Board } = require("../");
const board = new Board();
board.on("ready", () => {
// By including a base `elevation` property, the values
// received will be absolute elevation (from sealevel)
const altimeter = new Altimeter({
controller: "BMP180",
// Change `elevation` with whatever is reported
// on http://www.whatismyelevation.com/.
// `12` is the elevation (meters) for where I live in Brooklyn
elevation: 12
});
altimeter.on("change", () => {
const {feet, meters} = altimeter;
console.log("Altimeter:");
console.log(" feet : ", feet);
