4. EXPLANATION OF BLOCK
DIAGRAM
DHT11 is connected to the NODE MCU which is in turn connected to the
THINGSPEAK IOT CLOUD SERVER through the internet. We program the NODE
MCU through the Arduino IDE to post (publish) the data (temperature & humidity
data ) collected by the DHT11 Sensor on a channel created in the THINGSPEAK
CLOUD SERVER.

5. ABOUT
NODE MCU : Node MCU is a low-cost open source IoT platform. It initially included
firmware which runs on the ESP8266, and hardware which was based on the ESP-12 module.
support for the ESP32 32-bit MCU was added.
DHT11 : The DHT-11 Digital Temperature And Humidity Sensor is a basic, ultra low-cost
digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to
measure the surrounding air and spits out a digital signal on the data pin (no analog input pins
needed).
ARDUINO IDE : The Arduino Integrated Development Environment - or Arduino
Software (IDE) - contains a text editor for writing code, a message area, a text console, a toolbar
with buttons for common functions and a series of menus. It connects to the Arduino hardware to
upload programs and communicate with them.
THINGSPEAK CLOUD : Thing Speak is an IoT analytics platform service that
allows you to aggregate, visualize and analyze live data streams in the cloud. Thing Speak
provides instant visualizations of data posted by your devices to Thing Speak.
