Product Overview

The AM300 Series Indoor Air Quality (IAQ) Sensor is an advanced LoRaWAN®-enabled environmental monitoring solution designed to deliver comprehensive insights into indoor air conditions. Equipped with multiple high-precision sensors, it can monitor critical parameters such as temperature, humidity, CO₂ concentration, light intensity, motion, barometric pressure, TVOC, PM2.5, and PM10 (model dependent), helping organizations maintain healthier and more comfortable indoor environments.

Featuring a clear e-ink display, intelligent comfort-level indicators, and real-time data transmission, the AM300 Series enables facility managers to quickly assess air quality and respond to environmental changes. Its wireless LoRaWAN® connectivity ensures long-range communication with low power consumption, making deployment simple and cost-effective across offices, schools, hospitals, retail stores, and commercial buildings.

With support for local data storage, threshold alarms, and seamless integration with IoT platforms, the AM300 Series helps improve occupant well-being, enhance operational efficiency, and support smart building management through continuous environmental monitoring and actionable insights.
