Monitoring the climate from a remote dashboard

Today, most smart homes are connected to the Internet, and this allows the user to monitor their home. In this section, we are going to learn how to monitor your climate remotely. First, we are simply going to add a sensor to our Raspberry Pi Zero and monitor the measurements from a cloud dashboard. Let's see how it works.

The following image shows the final connections:

Exploring the sensor test

var sensorLib = require('node-dht-sensor'); 
var sensor = { 
    initialize: function () { 
        return sensorLib.initialize(11, 4); 
    }, 
    read: function () { 
        var readout = sensorLib.read(); 
        console.log('Temperature: ' + readout.temperature.toFixed(2) + 'C, ' + 
            'humidity: ' + readout.humidity.toFixed(2) + '%'); 
        setTimeout(function () { 
            sensor.read(); 
        }, 2000); 
    } 
}; 
 
if (sensor.initialize()) {
