The Milesight AM304L is a sensor for monitoring indoor environmental conditions, measuring temperature, humidity, light levels, and motion via LoRaWAN. The device is mounted on the wall using 3M adhesive tape or screws and configured via a mobile app using NFC or a downlink. Key technical features at a glance:
- Multiparameter Monitoring: Monitors values ranging from 0 to 60,000 lux and PIR (80° horizontally, 55° vertically, up to 3 m), providing a comprehensive picture of room conditions with a single device.
- Long battery life: Powered by four replaceable ER14505 Li-SOCl₂ batteries or via USB Type-C, it lasts up to approximately 14 years under laboratory conditions with a reporting interval of 10 minutes.
- Local Data Storage with Forwarding: Stores up to 4,320 measurement values, thereby reducing the risk of data loss in the event of network outages.
The AM304L is a Class A device with an internal antenna and supports both OTAA and ABP connection modes. It also supports the Milesight D2D protocol, which enables direct device-to-device communication without a gateway. The device has CE (RED) and FCC certifications and complies with RoHS requirements. The AM304L is particularly well-suited for office or classroom environments where continuous monitoring of indoor climate is required without frequent maintenance, as its design and installation require no wiring and only minimal on-site intervention.

The sensor monitors four key indoor parameters: temperature, humidity, light intensity, and motion.
It is designed for monitoring indoor environments such as offices, stores, classrooms, and hospitals, and it supports low-latency control via Milesight D2D.
The sensor includes internal data storage capable of holding up to 4,320 entries.
Under standard operating conditions (SF7, EU868), the battery life is estimated to be around 14 years.
No, this specific model does not support a display screen or a buzzer.
The device uses a passive infrared (PIR) sensor with a 3-meter range and a detection area of 80 degrees horizontally and 55 degrees vertically.
The sensor can be powered by four 2700 mAh ER14505 Li-SOCl2 batteries or through a 5V/1A USB-C connection.
The unit is designed for wall mounting and can be secured using either 3M adhesive tape or screws.
