Straw Mushroom Co2Co Condition Control

摘要

The Straw Mushroom Monitoring and Air Condition Control System has developed because of news which showed that family's farmers which consist of parent and their children when lack of respiration within the mushroom greenhouse. The cause of group dead may come from Carbon Dioxide (Co₂) or Carbon Monoxide (Co) gases. This project has developed by using a Node MCU board with Carbon Monoxide (MQ-9) and Carbon Dioxide (MH-Z14A) sensors to measure the level of Co₂ and Co gases and using a Raspberry pi boards to be a field server and an airflow controller. The network communication inside greenhouse has been using Wi-Fi router to be an access point for communication between the field server and sensor boxes through Message Queuing Telemetry Transport (MQTT). The network communication between the mushroom greenhouse and the main server has used a 3/4G router to connect the Internet for sending Co₂ and Co values to the database server. Warning and airflow control depend on the level of Co₂ and Co values which has conditions to alert and turn on the red light signal to protect farmers when lack of respiration within the mushroom greenhouse and turn on exhaust fans for controlling the airflow condition until the normal level of air condition.
