All-in-One Air Quality Transmitter – Multi-Parameter Detection with RS485 & LED

This advanced all-in-one air quality transmitter provides accurate, real-time monitoring of up to seven environmental parameters, including temperature, humidity, CO₂, PM2.5, PM10, VOC, and formaldehyde. Designed for intelligent indoor air management, it helps maintain healthy environments in commercial complexes, offices, airports, hotels, and schools.

The transmitter is equipped with high-precision sensors and supports RS485 Modbus communication—with optional isolation—to enable seamless data transmission across building automation systems. It can be configured via dial code or key interface depending on the installation type (indoor or top-suction).

Optional features include a digital display for on-site readings and a three-color LED indicator that visually communicates air quality status. The wide voltage input range, reverse polarity protection, and long-term reliability make it suitable for both new installations and system upgrades.
