2.1 Introduction
Aim of the Experiment :
To monitor the Temperature with NodeMCU on ThingSpeak.
This experiment is all about Humidity & Temperature Monitoring using DHT11 & NodeMCU on ThingSpeak. It explains how to log Humidity & Temperature data on the cloud. We can use Thingspeak as a cloud service provider and DHT11 to measure temperature and humidity.
Minimum Requirements :
USB Cable
NodeMCU ESP8266
DHT 11 module
Bread Board
Jumper Wire
DHT11 Humidity & Temperature Sensor:
The DHT11 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).
