Wide Selectable Range
The specification lists selectable measurement ranges to 50,000 ppm and extension up to 150,000 ppm.
MH-Z16 Wide-Range NDIR CO2 Sensor Module
The MH-Z16 is a wide-range NDIR CO2 module for animal husbandry, educational instruments, indoor air-quality equipment and industrial integration. Its specification supports selectable ranges to 50,000 ppm and extension up to 150,000 ppm.
BrandWinsen
Sensing PrincipleNDIR
Target GasCO2
Product TypeWide-Range NDIR CO2 Sensor Module
CO2 Sensing for OEM Integration
Product Overview
Wide-range carbon-dioxide measurement with fast response, UART and PWM outputs.
The MH-Z16 applies non-dispersive infrared technology for oxygen-independent CO2 detection with built-in temperature compensation and a long operating life.
Compared with compact indoor-only modules, its wider selectable range supports applications that may experience substantially elevated carbon-dioxide concentrations.
Designed for Reliable Integration
Key Features
Fast Response
T90 response time is specified below 30 seconds.
Short Preheat
The official specification lists a 10-second preheat time.
UART and PWM Outputs
Digital serial and PWM output modes support different control architectures.
Temperature Compensation
Integrated compensation supports a stable linear output.
Oxygen-independent Measurement
NDIR measurement does not require oxygen for carbon-dioxide detection.
