Trimble business center 4.0 download. Serial communication on pins TX/RX uses TTL logic levels 3.3V. Don’t connect these pins directly to an RS232 serial port; they operate at +/- 12V and can damage your ESP8266 board. Serial is used for communication between the Arduino board and a computer or other devices.

Components and supplies

Arduino UNO & Genuino UNO Arduino MEGA can be used.	×	1
NodeMCU ESP8266 Breakout Board	×	1
DHT11 Temperature & Humidity Sensor (4 pins)	×	1
Jumper wires (generic)	×	6

Apps and online services

Arduino IDE Arduino IDE with ESP board manager.

About this project

This project is all about serial communication between ESP8266-12(NODE-MCU) and Arduino. As we know ESP-12 have one analog pin where we can connect our analog sensor, But what else if we need more than one analog pin to connect more analog sensor and again if you want to send data to server like adafruit.io or your own server.

A video tutorial to follow, Hope it helps.
