Smart Environmental Air Quality Monitoring and Analysis System – Hospitality Enviro Tech

Overview

Hospitality Enviro Tech smart environmental air quality monitoring and analysis system is widely used in urban air quality monitoring and industrial air emission pollution monitoring. It can simultaneously measure various environmental pollution gases, particulate matter and meteorological parameters in the air. The system supports RS485 signal transmission, with data storage and export functions. Through the wireless acquisition terminal, the measurement data can be transmitted to the cloud platform in real time, and can be remotely controlled through the cloud platform. It is a new type of low-cost intelligent monitoring equipment, and it is an ideal equipment for environmental monitoring departments to monitor air quality.
