In this tutorial we will show how to build DS18B20 and ESP8266 temperature sensor without Arduino. We will use Arduino IDE and report temperature over WiFi on EasyIoT server. Sensor temperature is visible in EasyIoT server Web interface. If data logging is enabled you can see temperature chart...
In the first code example, I will show you how to take temperature readings from a single sensor and display the result in the Serial Monitor. The subsequent examples explain how to read multiple sensors with a single Arduino pin. Lastly, I will show you how to display the temperature on ...

To start up, please view the 1-wire library for Arduino using DS18B20 Temperature Sensor in the document column. You can connect the one-wire temperature sensor withSeeeduino V4.2, which is derived from Arduino and compatible with all Arduino platforms. ...
The DS18B20 digital temperature sensor provides 9-bit to 12-bit celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-wire bus that by definition requires only one data line(and...
