ESP8266 DS18B20 temperature sensor, Arduino IDE, EasyIoT Cloud




In this tutorial we will show how to build WiFi ESP8266 DS18B20 temperature logger connected to EasyIoT Cloud. All material costs less than 5$ on ebay.

Step 1: Materials

  • ESP8266 module
  • DS18B20 temperature sensor
  • 4.7 K esistor

Buying guide for ESP8266 DS18B20 temperature sensor is here.

Step 2: EasyIoT cloud configuration

Register to EasyIoT Cloud service. Then go to Configure->Modules->Add Module and select Analog Input module type. For first parameter set Description to Temperature, Unit to °C or °F, enable Log to database and set DB Avg.Interval to 10. For second parameter change Name to Settings.Icon1 and set Value to temperature.png. After you set values press button Save module.

DB logging means that we will log values in database, and historical values can be displayed in chart. DB Avg.Interval = 10 means that average value of parameter is inserted in database every 10 minutes.

After you save module module parameters gets ID. Copy ID for first parameter, because you will need it later.

Step 3: Program

We will program with Arduino ESP8266 IDE our ESP8266 directly. Program can be download on GitHub. In program set Acces Point username and password (AP_SSID, AP_PASSWORD) and instance parameter id (EIOT_CLOUD_INSTANCE_PARAM_ID). Instanceid/parameter id is wisible in WEB interface under configuration.

Connect ESP8266, DS18B20 and resistor. For power supply you can use 2 AA batteries. If everything is correct you can see temperature on EasyIoT Cloud http://cloud.iot-playground.com/ if you login with your username and password.
