INIR7-CO2-RS485
Overview
The INIR7-CO2-RS485 is a high-resolution NDIR (Non-Dispersive Infrared) carbon dioxide sensor module designed for industrial safety and hazardous environments. It features integrated electronics for signal processing and a robust RS-485 interface, providing a factory-calibrated output across a 0 to 5 percent CO2 range. The module includes full fault diagnostics, CRC error checking, and is optimized for stable operation in challenging conditions from -40C to +75C.
Why Choose This Part
This module eliminates the need for field calibration and complex analog signal conditioning by providing a direct RS-485 digital output. It offers high precision with 10ppm resolution and a detectivity level of 100ppm, combined with a wide input voltage range of 4.5V to 30V. The low 100uA sleep current makes it suitable for power-constrained remote monitoring stations.
Applications
Getting Started
Connect the module to an RS-485 transceiver or a PC using a USB-to-RS485 adapter to interface with the SGX Sensortech PC software for configuration. Ensure the power supply can provide at least 25mA at 12V for active operation. Utilize the built-in CRC and diagnostic registers in your firmware to validate data integrity and sensor health in real-time.
