infrareddigitalUART

Product Overview: MIPEX-05 [CO₂] is an ultra-low power NDIR sensor for continuous and accurate carbon dioxide measurement in explosive atmospheres. It uses selective infrared absorption with a dual-wavelength method to reduce the influence of humidity, dust, and optics contamination. The sensor is designed for portable and autonomous gas detection devices, combining ultra-low power consumption with precise dual-wavelength NDIR measurement.

Features:
- Ultra-low power consumption: Average power consumption less than 0.2 mW.
- Integrated microcontroller: Provides linearized and temperature-compensated digital output.
- Technology: Non-dispersive infrared (NDIR) sensing based on selective absorption of infrared light, using a dual-wavelength method to minimize the effects of humidity, dust, and optical contamination.
- Explosion-proof design: Sensor is designed in compliance with IECEx, ATEX, UL913, CSA.
- Standard 4th series size in plastic housing: Compact format Ø20.1 × 16.6 mm for portable device integration.
