MGS Technology - Model MIPEX-04 PPM [CH4] -Smart NDIR Sensor for Portable Gas Detectors

Smart NDIR sensor for portable gas detectors, offering precise methane detection with ultra-low power consumption for long-term autonomous use.

HIGH SENSITIVITY
Detects methane from as low as 50 ppm up to 5% vol with 10 ppm resolution.

LOW ENERGY DEMAND
Consumes less than 100 µA average current — ideal for battery-powered operation.

FOR PORTABLE DETECTORS
Optimized for compact gas detectors used in industrial safety applications.

BUILT-IN CONTROLLER
Delivers linearized and temperature-compensated data via UART, with no external signal processing required.

RELIABLE IN TOUGH CONDITIONS
Operates in a wide temperature range from –40 °C to +60 °C and up to 98% humidity.

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.
