Constant monitoring of five environmental parameters with a NodeMCU ESP8266 based weather station connected to the Internet

by Floris Wouterlood – The Netherlands –  Introduction In a previous paper I explored the Internet of Things (IOT), using a NodeMCU ESP8266 microcontroller board equipped with a single temperature sensing device. Data started flowing in and made this project so rewarding that a more ambitious project was considered almost immediately: building a complete weather […]

The DS18B20 temperature sensor – implementation with an Arduino

by Floris Wouterlood – The Netherlands Introduction One of the components of a weather station is a device that measures the temperature of the environment. Traditional analog instruments are based on the physical principle of expansion as a function of temperature. An affordable electronic solution with reasonably accurate sensing is the Dallas DS18B20 temperature sensor […]

An 128×64 graphic LCD display with ST7920 controller for the Arduino, displaying temperature and relative humidity

by Floris Wouterlood – The Netherlands – August 11, 2017 Summary Graphic 128×64 LCD displays are based on (monochrome) LCD technology, yet they offer interesting graphical capabilities because every pixel is individually addressable. These displays are more complicated to program than the ‘common’ 16×2 or 20×4 LCD displays that present two or four rows of […]
