This esp8266 module adapter is simple to flash. It makes the 5 V to 3.3 V conversion for power and RX pin and has a program switch (io 0) and a reset button to put the esp8266 into flashing mode. Use an USB-to-TTL-Serial adapter or an Arduino with USB chip to connect the adapter to PC. Esp8266, Esp-12e/12f, Esp12 manufacturer / supplier in China, offering Esp8266 Serial WiFi Adapter Module Esp-12e/12f V1.0 for Uno R3 2.4GHz, New Arrival B Plus 64 Bit Quad Core WiFi Bluetooth RS Raspberry Pi 3 Model B+, B Plus 64 Bit Quad Core WiFi Bluetooth RS Raspberry Pi 3 Model B+ and so on. 1 x ESP8266 ESP-12E Serial Wifi Transceiver Board Module. Arduino series motherboards or compatible motherboards can be used directly. WIFI @ 2.4.

In this tutorial we will show how to build 'Plug and Play' WiFi humidity and temperature sensor connected in EasyIoT Cloud. It shows how to send two parameters with one request with REST API V1. We will use ESP8266, DHT22 and Arduino IDE.

This is WiFi serial transceiver module, based on ESP8266 SoC.The SOC has Integrated TCP/IP protocol stack.It is TTL serial communication interface and its parameters can be set by AT command. It is widely used in networking, smart home project when it is connected to the wifi router.

Historical temperature and humidity chart. Data can be exported to CSV.

-ESP8266 WiFi module

-DHT22 humidity sensor

-3.3V power supply (battery or regulator)

See buying guide at the end of tutorial for details.

First we need to register to EasyIoT Cloud. After registration we do not need any other configuration, because sensor is 'Plug and Play'. We just need to remember Instance Id which is visible under Config->User Info.

Program is written in Arduino ESP8266 IDE. See Arduino ESP8266 IDE tutorial how to connect ESP8266 module to computer to upload program. Program is available at our GitHub. You will also need DHT22 library and REST API V1 library. Be sure to use library from our GitHub, because it's ported to Arduino ESP8266 IDE.

In program change Access Point username and password and Instance Id. Instance Id is under Config->User Info.

Instance id:

// change those lines
#define AP_USERNAME 'xxx'
#define AP_PASSWORD 'xxx'
#define INSTANCE_ID 'xxx'

If you are using Fahrenheit instead of Celsius use dht.toFarenheit(temp) function to report temperature in Fahrenheit.

First time when you connect sensor to power supply it will connect to access point and check module id. If module id is 0, then program will call REST API functions to get new token, adds new module and configure its parameters. Module Id and token are then stored in EEPROM. If module is already added to cloud (module id is different than 0), then program will skip this procedure and just read module parameters Id's. Then it reads temperature and humidity and sends it to Cloud in one POST. API function to post more parameter values is SetParameterValues.

Connection diagram is shown below. Instead of ESP8266-01 you can use different type of ESP8266. For power supply you can use 2 AA batteries or 3.3V regulator (see buying guide).
