CO2 Sensor 4-in-1 EM500-CO2 – Milesight (LoRaWAN)

The Milesight EM500-CO2 is built for places where CO2 is not just a comfort metric—it’s an operational and sometimes safety-critical parameter. It combines CO2 concentration, temperature, relative humidity, and barometric pressure in one rugged LoRaWAN device, making it a strong fit for outdoor sites and harsh environments where typical indoor sensors won’t last.

CO2 is measured via NDIR in the 400 to 5,000 ppm range. That supports practical use cases such as validating ventilation performance, tracking CO2 accumulation in storage/process areas, or monitoring environmental conditions in plant production. With LoRaWAN (EU868), the sensor can be deployed in distributed locations without local power or network wiring.

Concrete real-world examples:

Greenhouses: monitor CO2 and climate conditions to keep enrichment/ventilation aligned with actual readings.

Ventilation monitoring: CO2 as a proxy for air exchange, while humidity/temperature help detect condensation risk.

Fruit & vegetable storage: track CO2, humidity, and temperature to protect quality and spot ventilation issues early.

Wine fermentation areas/cellars: detect CO2 buildup that can settle near the floor and create dangerous pockets.

Outdoor/industrial monitoring points: climate + CO2 measurements where equipment must handle dust, weather, and temperature swings.

For reliability, the device includes on-device data storage (1,000 entries), retransmission, and data retrieval, plus threshold alarms and calibration support. Configuration is practical via NFC, USB Type-C, or downlink. Mounting options include pole, wall, or DIN rail.
