MH-440D Methane Infrared Gas Sensor Analog Voltage Signal High Sensitivity

MH-440D Methane Infrared Gas Sensor Analog Voltage Signal High Sensitivity

Introduction
MH-440D infrared gas sensor is a miniature universal intelligent sensor, which adopts NDIR theory to detect concentration of CH4 in air and has good selectivity stable performance, long life, also is independent of Oxygen. The inside temperature sensor could be used for temperature compensation. This miniature infrared gas sensor is developed by the tight integration of mature infrared
absorbing gas detection technology, micro machine workout and superior circuit design.

Features
1. High sensitivity, high resolution, fast response
2. Output method: UART, analog voltage signal
3. Temperature compensation, excellent linear output
4. Excellent stability, Long lifespan
5. Anti-poisons, anti-vapor interference
6. Can replace catalytic type gas sensor directly
