It's possible to build a WIFI enabled gateway running directly on an ESP8266 module. NodeMCU V2 also known as NodeMCU v1. Sold by www. In this article we are going to connect an ESP8266 Wifi shield to the CmuCam to send coordinates over Wifi. That's all you need to connect ESP8266 to Wi-Fi. STATION and wifi. Schematics and layout can be found here. com Temperature Logger with ESP8266 + DS18B20 + NODEMCU Today we are going make a remote Wi-Fi Internet connected temperature data logger using an ESP8266 WiFi module and a DS18B20 temperature sensor. Launch this app and set up a connection with MQTT broker.
