Gardening is a delightful hobby, but it can be a chore and one particularly bothersome job is watering the garden. Water it too often and the plants can die, too little and they can also die! But surely technology can offer a solution to this age old problem? Well yes it can, and in this tutorial we shall be using the Raspberry Pi Zero W, the lower power Pi with added Bluetooth and WiFi, along with two sensors, a soil moisture sensor to check if our garden needs water and an Adafruit Flora UV sensor to measure the ultraviolet index of the sun. This data is then emailed to our preferred inbox via a Gmail account that we can use to send the messages on demand.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
