WIRELESS CONTROLLED GREEN HOUSE AUTOMATION
The main goal of this project is to build a miniature greenhouse which is equipped with an automatic monitoring system. This monitoring system will constantly monitor the conditions in the greenhouse to ensure that it remains at preset temperature, light and humidity conditions.If these conditions differ from the preset levels, the monitoring system will automatically turn on certain devices to return the greenhouse to the required conditions.
MULTIKEY-ONE WIRE KEYPAD
The micro controller in the project will output the number of the push button pressed. There are several readymade keypads on the market, but those work with Matrix connections and require 7 pins for a 12 button pad. For new programmers, matrix keypads can be a bit tricky to programme.
