The cultivation of Grey Oyster Mushrooms is influenced by several factors such as ambient temperature, humidity, light and ventilation. The unpredictable Malaysian weather makes it difficult for this plant to get the optimum temperature to grow healthy and avoid bacteria. Hence, the development of an Automatic Environmental Control System of Grey Mushrooms House serves to solve the problem related to temperature and humidity for the cultivation of Grey Oyster Mushrooms. The main objective of this study is to design the Automatic Environmental Control System of Grey Oyster Mushrooms House, to develop a system to control the temperature, humidity and water level tank in the house of grey oyster mushrooms and to test the functionality of the Automatic Environmental Control System of Grey Mushrooms House. This study was developed by using the Waterfall Model which involves five phases. The five phases are Requirement Analysis Phase, Design Phase, Operation Phase, Testing Phase and Maintenance Phase. Besides, the Automatic Environmental Control System of Grey Mushrooms House successfully detects and control the temperature and humidity by using the DHT22 sensor and sends the data to the Blynk to run the system automatically when the temperature exceeds 30˚C or the humidity is less than 70%. This study involves the use of technology electronic components such as WiFi Module ModeMCU ESP8266, DHT22 sensor, Ultrasonic sensor and Liquid Crystal Display (LCD). The development of the Automatic Environmental Control System of Grey Mushrooms House might help agropreneurs to control mushrooms house more systematically, efficiently and also reduces the rate of damage to the mushrooms due to excessive mattering process. The findings of the study are evidenced by confirmation from experts. Improvements can be made by using solar energy as power and placing indicators such as Light Emitting Diode (LED) lights and even alarms to indicate the system is operating.
