NDIR carbon dioxide sensor EM500-CO2

USBLoRaWANrugged

Overview
The EM500-CO2 is an outdoor LoRaWAN® carbon dioxide (CO2) sensor combining four measurements in one rugged enclosure: CO2 concentration, temperature, humidity and barometric pressure. It is intended for outdoor or harsh environments (IP65) and for long-term wireless deployments with low power consumption and up to 10 years battery life under typical conditions. Key usability features include NFC configuration, internal LED indicator, internal USB Type-C for configuration/console and multiple mounting options (pole, wall, DIN rail).

Main features

• Four-in-one sensing: CO2 (NDIR), Temperature (MEMS), Humidity (MEMS) and Barometric Pressure (MEMS).
• CO2 range 400–5000 ppm, resolution 1 ppm; CO2 accuracy ±(30 ppm + 3% of reading) (0 °C–50 °C).
• IP65-rated enclosure (ABS + PC) for outdoor/harsh environments.
• LoRaWAN® wireless transmission (OTAA/ABP Class A) for long-range, low-power operation.
• Replaceable 19000 mAh Li-SOCL2 battery (ER34615); typical battery life up to 10 years (10 min interval, 25 °C).
• Easy configuration via NFC (mobile app) or USB Type-C (PC); supports local configuration and downlink updates.
• On-device storage (1000 entries), data retransmission, threshold alarms and calibration support.

LoRaWAN / Connectivity

• Compatible with standard LoRaWAN® gateways and network servers.
• Multi-region frequency support: CN470 / IN865 / RU864 / EU868 / US915 / AU915 / KR920 / AS923-1/2/3/4.
• Tx power examples: 16 dBm (868 MHz) / 20 dBm (915 MHz) / 19 dBm (470 MHz).
• Sensitivity: -137 dBm @ 300 bps. Antenna: internal.

Typical applications

• Greenhouse and agricultural monitoring (CO2 management for crops and livestock).
• Smart building ventilation and HVAC optimization (outdoor/harsh environment CO2 monitoring supporting indoor/outdoor control strategies).
• Environmental monitoring (e.g., support for early detection of anomalies) and storage facilities (fruit/vegetable/wine cellars).
• Remote outdoor sensing where long battery life and wireless deployment are required.

Cloud & Management

• Designed for integration with cloud platforms for visualization and management (dashboards, automated triggers, reports and real-time alerts).
• Mobile and PC configuration tools via NFC/USB; supports seamless onboarding and remote device management.

Mounting & Installation

• Mounting options: pole, wall or DIN rail; includes mounting bracket options.
• NFC-assisted configuration for quick commissioning and parameter setup.
