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 incorpor...

Overview of LM35 Temperature sensor: The LM35 datasheet specifies that this ICs are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in ˚ Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centi-grade scaling. The LM35 does not require a n y   e x t e r n a l   c a l i b r a t i on   o r   t r i m m i n g   t o   p r o v i d e   t y p i c a l   a cc u r a c i e s   o f   ± 1 » 4 ˚ C   a t   r oo m t e m p e r a t u r e a n d ± 3 » 4 ˚ C o v e r a f u l l − 5 5 t o + 1 50 ˚ C t e m p e r a t u r e r a ng e .

Overview of IFTTT If This Then That, also known as IFTTT. it is a free web-based service to create chains of simple conditional statements, called applets. An applet is triggered    by    changes    that    occur    within    other    web    services    such as Gmail, Facebook, Telegram, Instagram, or   Pinterest. For example, an applet may send an e-mail message  if  the user tweets using a hashtag, or copy a photo on Facebook to a user's archive  if  someone tags a user  in  a photo. In addition to the web-based application, the service runs on iOS and Android. In February 2015, IFTTT renamed its original application to IF, and released a new suite of apps called Do, which lets users create shortcut applications and actions. As of 2015, IFTTT users created about 20 million recipes each day. All of the functionalities of   the   Do ...
