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 ...
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...
