Milesight AM305L | LoRaWAN 5-in-1 IAQ & Occupancy Sensor | CO2, Temp, Humidity, Light, PIR

The Milesight AM305L is a compact 5-in-1 LoRaWAN indoor ambience sensor that measures CO2, temperature, humidity, light and motion (PIR) in a single wall-mounted unit. A built-in traffic-light indicator and buzzer give an at-a-glance view of comfort and air quality, while readings are sent over LoRaWAN for remote monitoring. Powered by replaceable batteries (up to ~11 years) or USB-C, it configures in seconds by NFC and pairs with the Milesight LoRaWAN gateway and Development Platform. Milesight D2D support enables direct, gateway-free control - ideal for offices, classrooms, stores and hospitals. Key Features 5-in-1 SensingCO2 (NDIR), temperature, humidity, light and PIR motion in one device for complete indoor comfort monitoring. Occupancy AwareA built-in PIR detects motion and occupancy, so the same sensor supports presence-based control and analytics. Clear Status & AlarmsTraffic-light LED and buzzer indicate comfort levels and trigger threshold alarms (e.g. high CO2) on the spot. Long Battery LifeUp to ~11 years on replaceable ER14505 batteries, or run on USB-C; configure quickly by NFC. Typical Applications •Offices & meeting rooms: track CO2 and comfort to drive healthier, demand-based ventilation. •Classrooms & schools: monitor air quality and occupancy for student wellbeing. •Stores & healthcare: keep tabs on environment and footfall in patient and retail spaces.

CO2, temperature, humidity, light level and motion (PIR) — five parameters in one LoRaWAN sensor. Does it have a screen? No display, but a traffic-light LED and buzzer indicate comfort levels and threshold alarms. (For an E-Ink display, see the AM307.) How is it powered and how long does it last? By 4 replaceable ER14505 Li-SOCl2 batteries (up to ~11 years) or USB-C (5V/1A). How do I configure it? Tap it with the Milesight ToolBox app over NFC, or send a LoRaWAN downlink.
