Sensor de monitorização ambiental interior LoRaWAN Milesight AM307L-868M com ecrã E-Ink, temperatura, humidade, CO2, TVOC, luz, PIR

The AM307L-868M stands out by combining seven environmental parameters in a single LoRaWAN node with a crisp 4.2-inch E-ink screen for at-a-glance readings. Unlike basic temperature loggers, it also tracks CO2, TVOC, barometric pressure, light, and occupancy via PIR, making it a complete indoor air quality and presence monitor.

Highlights

• LoRaWAN connectivity on 868 MHz (EU868, IN865, RU864), Class A/C
• Integrated sensors: temperature, humidity, PIR, light, CO2, TVOC, barometric pressure
• 4.2-inch E-ink display for low-power, high-contrast readouts
• Powered by 2x ER14505 Li-SOCl2 batteries (2700 mAh each) or DC 5V via USB-C
• Battery life up to 5 years depending on reporting interval
• NFC and USB-C for configuration
• Operating range: -20°C to +60°C, 0% to 95% RH non-condensing
• Temperature accuracy ±0.3°C, humidity accuracy ±3% RH
• CO2 measurement range 400 to 5000 ppm
• PIR detection distance 5 m, 90° horizontal and vertical angle
• Wall or desktop mounting, IP30, ABS+PC housing

In daily use

Deploy the AM307L-868M in offices, classrooms, or server rooms to monitor comfort and air quality. The E-ink screen remains readable without backlight and consumes power only on refresh, extending battery life. Configure thresholds and reporting intervals via NFC or USB-C, then let the device transmit data over LoRaWAN to your network server. The PIR sensor adds occupancy detection, enabling smart building automation based on room usage.
