ABSTRACT Andres, Mary Jane N., Dela Cruz, Jelly C., Palo Roxette M., Department of Computer Studies and Automation- College of Engineering and Computer February 2023. "OT BASED CONTROLLED ENVIRONMENT FOR Studies, Pampanga State Agricultural State University, Magalang Pampanga. MUSHROOM FARMING", Adviser Engr. Rosalie T. Tuazon According to Adhitya et al., (2017) Mushroom is defined as a macro- fungus with a distinctive fruiting body which can either be found growing on the ground or underground, Environmental condition is a significant factor that needs to be controlled in mushroom production, Oyster mushroom has a specific growing environment to ensure healthy and productive yield. It needs to grow in a temperature range of 22-28°C and humidity range of 60-80%. Thus, a farmer would manually spray water to the floor to control the temperature and humidity level in the conventional cultivation method. However, the mushrooms cannot Contact dìrectly with the water as a wet growing medium will damage the mushroom with bacterial or fungal infection (Hamidizade et al. , 2020). For this, the DHT22 temperature and humidity sensors are connected to the ESP8266 WiFi module to become loT (Internet of Things) sensors that send a lot of data to the intenet for monitoring. This enables users to monitor environmental conditions anywhere they access the internet. The system will automatically turn on and off the irigation system to keep the temperature at an optimum level The sensors were tested and compared with manual readings to ensure their accuracy. The respondents were taken from the locale and random agricultural students, as a result. Based on the researcher's evaluation of the respondents, they strongly agree that the "loT-Based Controlled Environment for Mushroom Farming" can be used as an altermative and much easier and faster way to control and monitor the environment for mushroom farming by being automated compared to a manual process. The respondents also strongly agree that the system was effective and easy to use for the users as well. The implementation of loT in the mushroom industry would greatly contribute to the advancement of the current mushroom industry, which still applies the traditional cultivation approach. As a result, this research aimed to design and develop an Internet of Things (loT)-based environment-controlled and monitoring system, such as temperature and humidity, that is remotely monitored and controlled through an Android application.
