Seeed Studio S-CO2-03 | Industrial CO2, Temperature & Humidity Sensor (RS485 & SDI-12)

The Seeed Studio S-CO2-03 is a high-performance atmospheric sensor designed to provide precise data for carbon dioxide levels, temperature, and relative humidity. Utilizing Non-Dispersive Infrared (NDIR) technology, the sensor delivers exceptional long-term stability and accuracy, even in environments with fluctuating conditions. This industrial-grade probe is a core component for smart agriculture, greenhouse automation, and urban environmental monitoring networks where reliable multi-parameter data is critical.

Technical Capabilities

NDIR CO2 Technology High-precision gas detection with built-in temperature compensation for stable readings. Standard Communication Supports Modbus RTU (RS485) and SDI-12 for seamless integration with PLCs and data loggers. IP66 Enclosure Ruggedized, UV-resistant housing protects sensors from rain, dust, and direct sunlight. Field Serviceable Supports manual zero-point calibration and software-based offset adjustments in the field.

Available Configurations

We offer the SenseCAP S-CO2-03 in two hardware variants to suit your installation requirements:

• Stripped Wires: Standard cable lead for direct wiring into terminal blocks or enclosures. • Aviation Connector: Equipped with a 6-pin waterproof connector for plug-and-play use with SenseCAP Sensor Hubs.

Industrial Deployment

The S-CO2-03 operates on a wide 5V to 24V DC power range, making it compatible with various industrial power systems. For wireless monitoring, it can be bridged to LoRaWAN® using the SenseCAP Sensor Hub or other Modbus DTUs. The louvered shield design provides optimal ventilation while preventing sensor saturation in high-humidity environments.
