Descrição
The Milesight AM307 is a 7-in-1 LoRaWAN indoor air quality sensor for offices, meeting rooms, classrooms, stores and public buildings. It measures CO2, TVOC, temperature, humidity, barometric pressure, light and motion, shows the readings on a 4.2-inch E-ink display with a traffic-light LED, and sends the data over LoRaWAN for comfort, ventilation and ESG reporting.

Key features
- 7 measurements in one device: CO2 (NDIR, 400–5000 ppm), TVOC, temperature, humidity, pressure, light level and PIR motion.
- Visible on the wall: 4.2-inch E-ink screen with emoticon indication, traffic-light LED and buzzer when thresholds are exceeded.
- Battery or USB powered: four replaceable ER14505 batteries or 5 V via USB Type-C.
- Accurate CO2: ±(30 ppm + 3% of reading) at 0–50 °C.
- Easy setup: wall mounting with 3M tape or screws, configuration via USB Type-C.

Sensor and software: what you get
On the sensor: live readings on the display, threshold alarms and LoRaWAN data. In software: air quality dashboards, alerts, occupancy-based ventilation and ESG reports. Use the AM307 with VemSpace, which comes with a 60-day free trial (see software plans). The hardware price does not include a software licence.
Installation and accessories
Mount the AM307 on an inside wall at breathing height, away from windows, doors and air vents. It needs a LoRaWAN gateway on the same frequency plan, such as the UG65 or UG67. For PM2.5, PM10 and HCHO or ozone choose the AM319; for room occupancy add the VS121.
Frequently asked questions
What does the Milesight AM307 measure?
CO2, TVOC, temperature, humidity, barometric pressure, light level and motion (PIR).
What is the difference between the AM307 and AM319?
The AM319 adds PM2.5, PM10 and HCHO or ozone, uses a photoacoustic CO2 sensor and is USB Type-C powered only. The AM307 can run on batteries.
How long do the AM307 batteries last?
Milesight's lab figure is about 3.9 years at SF7 with a 10-minute interval; less at higher spreading factors. It can also run on USB Type-C power.
Which LoRaWAN frequency do I need?
868M for Europe, the Middle East, Africa, India and Russia; 915M for the Americas, Australia, Korea and most of Asia-Pacific.
