Product Specification

NDIR Sensor CH4 Methane Sensor PPM MIPEX-04 PPM （CH?）Description：

MIPEX-04 PPM （CH?） 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.
