Description

Winsen MH-440D NDIR infrared CH4 sensor UART, 3.6～5 V DC
description:
MH-440D infrared gas sensor is a miniature universal intelligent sensor. It uses NDIR theory to detect the concentration of CH4 in air. It has good selectivity, stable performance, long life and has nothing to do with oxygen. An internal temperature sensor is available for temperature compensation. This miniature infrared gas sensor was developed by tightly integrating sophisticated infrared absorption gas detection technology, micromachined exercise and superior circuit design.
It is easy to use and can directly replace the catalytic component and is widely used in various occasions of flammable and explosive gases.
feature:
High sensitivity, high resolution, low power consumption
Output mode: UART, analog voltage signal
Temperature compensation, excellent linear output
Excellent stability, long life
Anti-virus, anti-steam interference
Can directly replace catalytic gas sensors
Application areas:
Widely used in HVAC refrigeration, indoor air monitoring, industrial process control and safety protection, agriculture and animal husbandry.
Packing: 1PC
Warranty period: 120 days
