One of the easier approaches to modern electronics, is to build projects by combining ready-made modules. Only some wiring and -in most cases- software is needed to create a new device, like the one we present in this article. The designer is the 15-year-old student Aarav Garg from India, who is more than happy to present his Pocket Weather Station in our magazine. It is constructed using an Arduino Nano, a 0.96” OLED display, a DHT11 humidity/temperature sensor, and is powered by a LiPo battery that can be charged via a USB charging module. A tailor-made, 3D printed enclosure completes this handy, portable device.
