Real time temperature data monitoring using ThingSpeak

Whats exactly ThingSpeak?

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.

It enables the creation of sensor logging applications, location tracking applications, and a social network of things with status updates”.

launched by ioBridge in 2010 as a service in support of IoT applications.

ThingSpeak is an Internet of Things (IoT) platform that lets you collect and store sensor data in the cloud and develop IoT applications.

ThingSpeak IoT platform provides apps that let you analyze and visualize your data in MATLAB, and then act on the data.

The Sensor data sent to ThingSpeak from Arduino, Raspberry Pi, BeagleBone Black, and other hardware.Think speak IOT

A Complete tutorial Series on Introduction of  NodeMCU/ESP8266 here..

In this tutorial, LM35 temperature sensor can be used with esp8266 or Nodemcu and program from Arduino IDE, the lm35 has used to send data to thingspeak and it was really productive there is no sudden spike in temperature change, it was gradual and results are quite good.”
