The AM300(L) series is a compact indoor ambience monitoring sensor designed for measuring a range of parameters including temperature, humidity, light, CO2 concentration, HCHO/O3 levels, TVOC, barometric pressure, PM2.5, PM10, and motion. Data is displayed in real-time on an E-ink screen, aiding in the assessment of indoor environment and comfort. The AM300 series is suitable for various settings such as offices, stores, classrooms, and hospitals. It transmits sensor data using LoRaWAN® technology. When integrated with Milesight LoRaWAN® gateway and IoT Cloud, users can manage all sensor data remotely and visually.
Product Features
- Multiple Integrated Sensors: Measures humidity, temperature, CO2, light, barometric pressure, PM2.5, and PM10.
- Multiple Display Modes: Offers clear emoticons on the screen for easy understanding of comfort levels.
- Power Supply Options: Supports both batteries and DC power supply.
- Traffic Light Indicator and Buzzer: Indicates device status and threshold alarms.
