Description

The Milesight AM307 is a 7-in-1 LoRaWAN indoor air-quality sensor from the AM300 series, giving a complete overview of indoor environmental health. In one device it measures CO2, TVOC, temperature, humidity, light, barometric pressure, and occupancy (PIR) — ideal for offices, classrooms, healthcare, and public buildings.

A 4.2-inch E-ink display shows readings with an emoticon and traffic-light air-quality status at a glance, backed by a buzzer and LED for threshold alarms. It's available with the display (AM307) or as a lower-cost display-less version (AM307L) for back-end monitoring.

Core Capabilities

7-in-1 Air-Quality Sensing NDIR CO2 (400–5000 ppm), TVOC, temperature (±0.2°C), humidity (±2% RH), ambient light, barometric pressure, and PIR occupancy — comprehensive indoor environment data from a single device.

At-a-Glance Display & Alarms The AM307's 4.2-inch E-ink screen shows readings with emoticon and traffic-light air-quality levels (the AM307L omits the screen). Both include a traffic-light LED and buzzer that respond when pollutants exceed the configurable alarm threshold.

Battery or USB-C, Smart Power-Saving Powered by 4 × 2700 mAh ER14505 batteries or USB Type-C (5V/1A). A smart screen mode pauses the display when the PIR detects vacancy for 20 minutes, extending battery life — around 3 years (AM307) and 4 years (AM307L).

NFC/USB-C Config & Cloud Configure tool-free via NFC (Milesight ToolBox app) or USB-C (PC software), with CO2 manual and auto-background calibration. Integrates with Milesight IoT Cloud and the Development Platform, with on-device data storage and retransmission.

Typical Applications

Offices & Smart Workplaces: Monitor CO2 and comfort to drive demand-based ventilation and improve productivity, with at-a-glance air-quality status on the AM307 screen.

Schools & Classrooms: Track CO2 and TVOC to maintain healthy learning environments and inform ventilation scheduling across campuses.

Healthcare & Public Buildings: Maintain compliant air quality in waiting rooms, wards, and public spaces, with buzzer/LED alerts when thresholds are exceeded.

Building Management & HVAC: Feed multi-parameter IAQ and occupancy data into BMS/HVAC systems (via a LoRaWAN gateway) for energy-efficient, occupant-driven control.

Technical Integration

The AM307 operates on LoRaWAN® Class A (OTAA/ABP) across CN470, EU868, US915, AU915, AS923, KR920, IN865, and RU864 bands, configured via NFC (Milesight ToolBox app) or USB-C (PC software). CO2 supports manual and automatic background calibration. It integrates with Milesight IoT Cloud and the Milesight Development Platform and works with standard LoRaWAN network servers (e.g. The Things Stack, ChirpStack). Power is via 4 × 2700 mAh ER14505 batteries or USB Type-C (5V/1A). The IP30 enclosure (100.8 × 114 × 22 mm) mounts with 3M tape or wall screws and operates from −20 °C to +60 °C (E-ink screen 0–40 °C). For deployment or gateway selection support, contact the ShopIoT technical team.

Frequently Asked Questions

What does the AM307 measure?

CO2, TVOC, temperature, humidity, ambient light, barometric pressure, and PIR occupancy — seven parameters in one device. (For particulate matter, choose the AM308; for HCHO/O₃, the AM319.)

What's the difference between AM307 and AM307L?

Both have the same 7-in-1 sensors, buzzer, and traffic-light LED. The AM307 adds a 4.2-inch E-ink display; the AM307L has no display and a longer battery life (~4 years vs ~3 years).

How is it powered?

By 4 × 2700 mAh ER14505 batteries or USB Type-C (5V/1A). A smart screen mode pauses the display when the room is vacant to extend battery life.

Does it need a LoRaWAN gateway?

Yes. It reports over LoRaWAN® (Class A) to a gateway and network server (e.g. The Things Stack, ChirpStack, or Milesight UG56/UG65). A gateway is sold separately.

How is the CO2 sensor calibrated?

It supports manual calibration and automatic background calibration (ABC) via the Milesight ToolBox app or downlink commands.

How is it configured and mounted?

Tool-free via NFC (mobile app) or USB-C (PC software); it mounts with the included 3M tape or wall screws.
