The advantage of the ESP8266 over Arduino and other controllers is the builtin Wi-Fi. In this Instructable I will show you how with the help of Visuino you can use twoESP8266 modules to make a remote LCD Display for Temperature and HumidityDHT11 sensor.
In the Instructable, I will use 2 NodeMCU modules. One version 0.9, and the other 1.0. The NodeMCU are the easiest way to program and experiment with ESP8266controllers. This Instructable however can easily be done with other modules, and the Sensor module can even use ESP-01 module as it needs only one GPIO pin to connect to the DHT11 sensor.

Step 1: Components
- 2 NodeMCU ESP8266 boards (I used both NodeMCU 0.9, and NodeMCU 1.0 versions, but any other combination, or even stand alone ESP-12 will work)
- One DHT11 Sensor module I got from this cheap 37 sensors set
- One I2C 16×2 LCD Display (Back side of the LCD with the I2C adapter showed on Picture 2)
- 7 Female-Female jumper wires
