Development of an Airflow Monitoring System for Air Handling Unit using IoT

Abstract

This paper presents the development of an airflow monitoring system for air handling units using NodeMCU ESP32. The main purpose of this project is to improvise the use of microcontroller with on-par performance for industrial applications. This proposed system consists of two sensors that measure airflow from the air handling unit. The first sensor is an airflow speed, which measures the airflow speed from the air handling unit. The second sensor detects and indicates the temperature and humidity of the airflow. The testing parameters show very good correlations among variables, indicating the efficiency of the system to monitor the airflow.
