The aim of project is to build temperature and humidity controller for Mushroom Environment based on Arduino. The project comes with 3 sensors: Thermistors for temperature sensor, HS1100 for humidity sensor and MG811 for C02 sensor.
Arduino will read the sensors data and process it. When the mushroom environment is dry, Arduino will turn on sonic humidifier and an air pump via relay. Otherwise, when the environment to wet, it will set two heating pads on via relay. The controller interface is equipped with 16×2 LCD for display and buttons for input.
