15. Measure Temperature and Upload data in ThingSpeak


Overview of ThingSpeak IoT platform

According to its developers, "ThingSpeak is an open-source Internet of Things (IoT) application and API to store and retrieve data from things using the HTTP protocol over the Internet or via a Local Area Network. ThingSpeak enables the creation of sensor logging applications, location tracking applications, and a social network of things with status updates".
ThingSpeak was originally launched by ioBridge in 2010 as a service in support of IoT applications.
ThingSpeak   has   integrated   support    from    the    numerical    computing    software MATLAB from MathWorks, allowing ThingSpeak users to analyze and visualize uploaded data using MATLAB without requiring the purchase of a MATLAB license from MathWorks.
ThingSpeak has a close relationship with MathWorks, Inc. In fact, all of the ThingSpeak documentation is incorporated into the MathWorks' MATLAB documentation site and even enabling registered MathWorks user accounts as valid login credentials on the ThingSpeak website. The terms of service and privacy policy of ThingSpeak.com are between the agreeing user and MathWorks, Inc.

Connection of LM35:


The Output pin of LM35 is Connected to A0 pin of ESP8266 Module, Ground pin is connected to the ground pin of ESP8266 Module and VCC is connected to 3V3 Pin of ESP8266 module.


Method to interface IFTTT:

Step1: Search Thingspeak in browser and open it. 


Step2: click on “Get Started For free” and create account.


Step3: click on New channel.


Step4: Edit name and choose field and its name. then, click on save channel according to below figure.


Step5: After save channel open a new window. In this window have field chart, API key, channel setting and many more. Now click on API keys and get API keys as shown in figure.


Method to make code using TUNIOT:

Step1: Search TUNIOT in browser and open it. Then, we see Two Blocks, first block is Setup and Second Block is main Loop. In Left side given the blocks.

Step2: first, we disconnect network. Go-to—IOT—IOT STATION—Select Disconnect.


Step3: Now Esp8266 Connect with a network. So, we use network ssid and password. So, GOTO—IOT—IOT Access Point—WIFI ssid and password block. And change ssid and password according to your WIFI network.


Step4: when network is not connected then network is continuously search and try to connected. GOTO—IOT—Select Repeat while.


Step5: Then Go to—IOT—Thingspeak and Select field Block and in place of value we delete Text block and add Analog pin. So, go to—IN/OUT— ANALOG—Select Analog pin according to figure. And also fill API key in API key Text bar.


Step6: then add delay block and enter delay value is 3000 milliseconds and match all the blocks according to the below figure.


Step7: block arrangement is completed then convert all the blocks in code.  Then click on Video icon and enter name and press Ok. After, downloading the Code open in Arduino IDE and upload in NodeMCU.


Step8: After uploaded the code open ThingSpeak Channel makes by above process and see in field chart your data is directly Uploaded time to time in this chart according to figure.

Overview of NEO6M GPS Module This module is one of popular GPS modules on the market and is also cheap to buy. The location data provided by it is accurate enough to satisfy most applications. And for it to be included in smart phones and tablets design points out its efficiency. This module is famous among hobbyist and engineers altogether who want to work on applications involving navigation. The NEO-6MV2 is a GPS (Global Positioning System) module and is used for navigation. The module simply checks its location on earth and provides output data which is longitude and latitude of its position. It is from a family of stand-alone GPS receivers featuring the high-performance u-blox 6 positioning engine. These flexible and cost-effective receivers offer numerous connectivity options in a miniature (16 x 2.4 mm) package. The compact architecture, power and memory options make NEO-6 modules ideal for battery operated mobile devices with very strict cost and space constraints. Its...

Overview of Magnetic Door Sensor Door sensors have one reed switch and one magnet, creating a closed circuit. If someone opens an armed door or window, the magnet is pulled away from the switch, which breaks the circuit and triggers an event. Depending on your setup and what mode your system is in, this could be a discreet text, a chime alert, or a full-blown alarm. Connection of Magnetic Door Sensor In magnetic Door sensor have not Positive and Negative terminals. So, you   can connect One terminal to D1 pin of NodeMCU and another Terminal to Ground of NodeMCU as shown in figure. Program #define BLYNK_PRINT Serial  #include  <ESP8266WiFi.h>  #include <BlynkSimpleEsp8266.h>  BlynkTimer timer; int flag=0; // You should get Auth Token in the //Blynk App. // Go to the Project Settings (nut icon). char auth[] = "WRSu1DJITg2rSoBDuefgaWdMnCfBWDCY"; // Your WiFi credentials. // Set password to "" for open networks....
