We are going to send temperature and humidity data to thingspeak using DHT11, ESP8266 module and Arduino board. UPDATE: An easier method on How to Send Data to Thingspeak (without sensor) using ESP8266 and NodeMCU is explained here. Final circuit diagram for sending temperature and humidity data to thingspeak.Possible errors while uploading a code to ESP8266 and solutions.Circuit diagram for uploading a code to ESP8266.How to install ESP8266 board package to Arduino IDE?.What is Thingspeak platform, how to create an account and get API key?. In this post we will learn how to connect your Arduino projects to Wi-Fi and observe data in real time on Thingspeak. In a previous tutorial we saw how to send data to thingspeak using GSM modem and Arduino which didn’t require a Wi-Fi hotspot. In this post we are going to learn how to send sensor data to Thingspeak IoT platform using ESP8266 and Arduino.
