Ultra-low power methane sensor for compact gas detectors
MIPEX-04 PPM CH₄ is a high-performance NDIR sensor with 10 ppm resolution, designed to detect methane at low concentrations — from just 50 ppm up to 5% vol.
MIPEX-04 ppm [CH₄] is a high-precision NDIR sensor for low-level methane detection in portable gas detectors used for industrial safety.
It features ultra-low power consumption (less than 100 µA average), stable long-term performance, and high sensitivity from just 50 ppm up to 5% vol. The sensor supports UART communication and a wide input voltage range (2.5–5.0 V), making it easy to integrate into battery-powered devices.
