ProSight LFG303 All-in-One Air Quality Transmitter Multi-Parameter Detection with RS485 & LED is a smart indoor air quality transmitter with real-time monitoring of up to 7 parameters. Includes RS485 output, LED indicator, and optional display—ideal for offices, smart buildings, and commercial spaces.
The ProSight LFG303 All-in-One Air Quality Transmitter Multi-Parameter Detection 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.
