Introduction

This sensor is based on the Non-Dispersive Infrared (NDIR) absorption principle, capable of continuously measuring CO₂ concentration, air temperature, and air humidity per unit volume of air. It outputs data via universal interfaces for real-time environmental monitoring, providing users with reliable sensing data. The device features 6 data lines, supporting both RS485 (Modbus-RTU / Modbus-ASCII) and SDI-12 standard communication protocols, compatible with 5V–24V external supply voltage, and works with most data acquisition devices — enabling out-of-the-box data access and system integration without complex development. The sensor operates in low-power mode, with current as low as the μA level (SDI-12). It adopts the NDIR absorption principle with a single-chamber dual-channel design, and incorporates a PTFE breathable membrane combined with a protective housing to enhance air permeability while protecting the sensor, thereby improving detection accuracy. Using high-quality chips, the device operates stably and reliably. Its compact form factor allows easy installation, making it widely applicable in scenarios such as greenhouses and urban environments.
