In the previous tutorial I showed how to build a weather station using DHT11 and BMP180 with an Arduino. However, the project has a downside which is the power consumption of the 16X2 LCD. If we were building a battery powered project with the desire to last for several weeks and probably several months, like a weather station for instance, then we’ll have to replace the LCD keypad shield from the previous tutorials and go for something like the low powered Nokia 5110 84×84 LCD display. In this tutorial I will be showing you how to drive this display with the Arduino and thus build projects with longer battery life.
