[Arduino Project]#Remote Monitoring of Ultrasonic Sensor Value Using IoShield-A & Cloud Server

My post explains how to monitor ultrasonic sensor value remotely using Arduino, ioShield-A & Xively Server.

Arduino Uno board is used for controlling whole system and measuring the sensor value. I'm using ioShield-A (which is based of W5500) for processing the TCP/IP connection.

Step 1: Parts & Program

• Arduino Uno (MCU) : http://arduino.cc/en/Main/ArduinoBoardUno
• Ethernet Shield (ioShield-A / WIZnet) : http://www.shopwiznet.com/ioshield-a
• Ultrasonic seonsor (NT-TS601, OEM) : http://www.datasheetarchive.com/datasheet/NT+TS601...
• Temperature (DHT11, DFRobot) :
  • Library : http://playground.arduino.cc/main/DHT11Lib
  • Datasheet : http://www.micropik.com/PDF/dht11.pdf
• LED, Resistor
• Jumpers
• breadborad
• Fritzing : http://fritzing.org/home/
• Arduino Sketch : http://arduino.cc/en/Main/Software

I drew the schematic at the Fritzing.

Step 2: Operation Block Diagram

Each node and part operate and communicate as shown in below block diagram.

Step 3: Method the Using Xively 1/6

Now, I will connect to Xively(cloud service), one of the most popular cloud service in the world.

1. Connect to http://xively.com

Step 4: Method the Using Xively 2/6

2. After log-in, go to “Development Devices”

Step 5: Method the Using Xively 3/6

3. Input the “User Agent”, “Feed ID” & “APIKEY” in the Arduino Sketch

Step 6: Method the Using Xively 4/6

4. Now, you can remotely monitor the change of the sensor value.

Step 7: Method the Using Xively 5/6

// replace your Xively api key here
#define APIKEY “YfqMfUI4h9QIZ0dL8JQTpqfhIfaeXwGOc7qrpPeoFHecVPEI” 
// replace your feed ID#define USERAGENT “make fair”
 // user agent is the project name
#define FEEDID 863324820 

Below code is to turn on the LED if the sensor value is under 10cm.

In case of String dataString = “Ultra,” and dataString += “\nTemperature, “, they must be same with the channel name that you made at the Xively

Step 8: Method the Using Xively 6/6(video)
