Learn how to connect your NodeMCU (ESP8266) to a Laravel backend! In this tutorial, you'll see how to send sensor or device data from NodeMCU to Laravel using HTTP requests (POST/GET), making it ...

Sensor Node The WeMos module I used has DHT-11 and DHT-22 shields available. The sensor is hooked up to NodeMCU pin D4, which is GPIO2 in the ESP8266 datasheet.

As usual I’ll be using a NodeMCU board (I really did order a lot of them) which uses an ESP8266, but there’s no reason this would be difficult to achieve on an Arduino-based device.

This board is a complete Internet radio based on ESP8266 Module and the Arduino. The board has a stereo earphone jack plus two speaker connectors and a on-board 2.5w HiFi amplifier.
