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.

Flora UV Index Sensor – Si1145 Light Sensor: Your wearable can now keep you from getting sunburnt, with the Flora digital UV index sensor. We took our popular SI1145 UV index sensor and cut out everything you don’t need for using with a Flora. It’s small, round, and connects to the I2C bus pads. Flora can even use our library code to get calibrated light level and UV index data from the sensor. (read more)
