How to send data from ThingSpeak to ESP8266 ( Arduino )?
It sends data of the sensors connected (DHT11 & LDR) to the ThingSpeak web-server. Now I want to perform some actions according to data on ThingSpeak Server ( like if temperature exceeds turn on fan e.t.c). I’ve searched and I found that there’s a React App on thingspeak which will trigger event if data exceeds some values,
What can you do with ESP8266 HTTP POST?
ESP8266 HTTP POST Data (ThingSpeak) In this example, the ESP8266 makes an HTTP POST request to send a new value to ThingSpeak. ThingSpeak has a free API that allows you to store and retrieve data using HTTP. In this tutorial, you’ll use the ThingSpeak API to publish and visualize data in charts from anywhere.
Is the ESP8266 connected to the WiFi hotspot?
If you can’t see any data on your Thingspeak’s private view, then you should check wheather your ESp8266 is connected to your Wi-Fi hotspot or not. You can do this by checking the connected devices in your router’s admin panel. Your connected ESP8266 on admin panel will be like ESP, followed by some numbers as shown below:
Can a ESP8266 be used as a standalone device?
The ESP8266 can operate as a standalone device as it sport a 32-bit microcontroller chip, RAM, GPIO pins and a flash memory which can be programmed using Arduino IDE. But this module have only two GPIO pins and may limit our number of sensors and peripherals which we may connect to it.
