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...

The paper describes the development of a Wireless Sensor Network for Temperature and Humidity Monitoring System. The prototype is based on NodeMCU ESP8266 module that automatically record the current parameters and allowing the user to interact with the monitoring system wirelessly. A total of three ...
Unless otherwise specified, the power consumption measurements are taken with a 3.0V supply at 25°C of ambient temperature. All transmitters’ measurements are based on a 50% duty cycle.5.3 Wi-Fi Radio Characteristics The following data are from tests conducted at room temperature, with a 3.3V...
