DevDuino – Learn and Explore Arduino World
DevDuino is a Fully Redesigned and Enhanced Arduino-Compatible Board with Plenty of Must-Have Features. It features a 128x64 OLED display, along with a variety of LED indicators, RTC module, a slot for a micro SD card, and many other convenient features. The project is live on...
Continue ReadingArduino Weather Station with DHT11 and BMP180
In the previous tutorial I showed you how to build a weather station using only the DHT11 sensor and I said the readings from this sensor is fairly accurate. In this tutorial, I will be using the DHT11 to measure only the humidity and BMP180 to measure pressure and temperature. That’s...
