Greenie

This repo is a work in progress. Its goal is to provide some automation realted to a greenhouse. Currently, greenie reads the temperature and humidity from an SHT31-D and alternates showing the readings and the current network info on a 16x2 LCD.

The utils/relay_test.py shows how a set of relays can be controled. This will be expanded on in a later version of the code. To use relay_test.py as written you will need to install pigpio. On Raspbian this can be done like so:

sudo apt-get update
sudo apt-get install pigpio python-pigpio python3-pigpio

• 1 x Raspberry Pi Zero W
• 1 x Adafruit SHT31-D temperature and humidity sensor
• 1 x SainSmart 4-channel relay module
