AM305L-868M: LoRaWAN 5-in-1 Indoor Environment Monitoring Sensor: Temperature, Humidity, Light, PIR, CO2

The AM300 series is a compact indoor environment monitoring sensor for measuring temperature, humidity, light, CO2 concentration, HCHO/O3 level, barometric pressure, PM2.5, PM10, and motion. Data will be shown on the E-ink screen in real-time, which helps to measure the indoor environment and comfort. The AM300 series is widely used for offices, stores, classrooms, hospitals, etc. Sensor data is transmitted using LoRaWAN ® technology. By combining the Milesight LoRaWAN ® gateway and Milesight IoT Cloud, users can manage all sensor data remotely and visually.

**AM305L is a 5-in-1 sensor**: A single device capable of detecting 5 parameters:

- **Temperature**
- **Humidity**
- **Motion (PIR)**
- **Light**
- **CO2**
