Connecting Grove Temperature Sensor to Intel Edison

In this blog we will see how to connect Grove light sensor and temperature sensor to edison board.

Connect LCD to I2C port, Temperature sensor to A0 and Light sensor to A1.

Create a blank project using Blank template and copy paste the code in main.js

Program :

/*jslint node:true, vars:true, bitwise:true, unparam:true */
/*jshint unused:true */
// Load Grove module
var groveSensor = require('jsupm_grove');

// we want mraa to be at least version 0.6.1
var mraa = require('mraa');
var version = mraa.getVersion();

if (version >= 'v0.6.1') {
 console.log('mraa version (' + version + ') ok');
 useUpm();

}
else {
 console.log('meaa version(' + version + ') is old - this code may not work');
}


/**
 * Refresh the data periodically 
 * 
 */
function showData(display) {
 var red = 0;
 var green = 50;
 var blue = 200;
 display.setColor(red, green, blue);
 setInterval(function() {
 display.clear();
 display.setCursor(0,0);
 display.write('Temperature:' + getTemperature() + 'C');
 display.setCursor(1,0);
 display.write('Light:' + getLDR() + 'Lux'); 
 }, 1000);
}
var light=new groveSensor.GroveLight(1);

function getLDR(){
 return light.value();
}
var temp=new groveSensor.GroveTemp(0);
function getTemperature(){
 var data=temp.value();
 return data;
 //return (data*500)/1024;
}

/**
 * Use the upm library to drive the two line display
 *
 */
function useUpm() {
 var lcd = require('jsupm_i2clcd');
 var display = new lcd.Jhd1313m1(0, 0x3E, 0x62);
 showData(display);
}

Load and run the project from XDK, you should see something like this
