Product Overview
The Integrated IR (INIR) sensor is a user-friendly digital gas sensor utilizing SGX Sensortechs latest Infrared technology. Designed for enhanced reliability and minimized fault probability, it incorporates a microcontroller with an ARM7 core. The INIR sensor processes raw signals to output a linear, temperature-compensated signal proportional to gas concentration, available in both digital and analog forms. It features a triple-range detection capability with linear approximation for Carbon Dioxide (5%) and Methane (5% and 100%), automatic range switching, and high resolution up to 10ppm. Ideal for integration into gas detection instruments, it significantly reduces development time and expertise required. The sensor can be factory calibrated for Methane or Carbon Dioxide, and an evaluation kit with PC software is available for easy testing and calibration.
