Lambda Function in Node.js

This is our Lambda function for data enrichment using AWS IoT Anlytics. No additional Node modules are needed.
// Handler called by IoT Analytics
exports.handler = function handler(event, context, callback) {
//add timesteamp to incoming data and name it "ServersideTimestam"
        event[0].ServersideTimestamp =;
        // Return the data        
        callback(null, event);
 //   });

Graphing website to be hosted on S3

This is our static website to be hosted on S3 which reads data from IoT Analytics held in a partition on S3. The webpage ingests data with an AJAX GET, then parses the data with RegEx's placing the data into arrays for each variable. Finally, the data is graphed using Google Charts brought in to our website from a CDN. Make sure to keep this in a public bucket, giving everyone read permission unless you want to customize it with API Gateway or assign federated or other access with Cognito. Do not store passwords or other sensitive information in a public S3 partition.

MQTT Data to AWS IoT - No Sensor

This Arduino sketch (mqtt-client2.ino) connects your Wio LTE to AWS IoT Core if you don't have an external sensor. It generates a fake data JSON data package to publish to AWS IoT Core.

MQTT Data to AWS IoT -DHT Sensor

This Sketch (mqtt-dht11.ino) connects to AWS IoT from the Wio LTE utilizing real sensor data from a connected DHT device.
