There’s nothing quite like clean air-dried clothes fresh from the line, unless an unexpected shower ruins everything. Ever heard that cry of “RAIN!” from a member of the household, only to be followed by the thundering of feet down the stairs in a desperate bid to save your Sunday best from another trip to the washing machine?
Catch the rain as soon as it starts with this simple standalone build that alerts your phone as soon as it detects raindrops. There’s no soldering required, just a few cables. We need low power consumption and WiFi, so this is a perfect project for a Raspberry Pi Zero W.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
