MH-Z14B Carbon Dioxide Gas Sensor Introduction: The MH-Z14B carbon dioxide gas sensor (hereinafter referred to as the sensor) is a universal intelligent small sensor that utilizes the principle of non dispersive infrared (NDIR) to detect the presence of CO2 in the air. It has good selectivity, oxygen free dependence, and long lifespan. Built in temperature compensation; It has both digital output and PWM output, making it easy to use. This sensor is a high-performance sensor that combines mature infrared absorption gas detection technology with precise optical path design and sophisticated circuit design. Main applications: HVAC equipment, air quality monitoring equipment, Dedicated outdoor air system, air purification equipment, smart home Features: 1. The air chamber is treated with gold plating, which is waterproof and corrosion-resistant 2. High sensitivity, low power consumption, and excellent stability 3. Temperature compensation, excellent linear output, and long service life Technical parameters: Product model: MH-Z14B Detection gas: carbon dioxide Power supply voltage: DC (5.0 ± 0.1) V Average current:<60mA (@ 5V power supply) Peak current: 150mA (@ 5V power supply) Interface level: 3.3V (compatible with 5V) Measurement range: 0-10000ppm (expandable to 50000ppm) Output signal: Serial port (UART) (TTL level 3.3V) PWM Preheating time: 10s Response time: T90<90s Working temperature: -10 ℃~50 ℃ Working humidity: 0-95% RH (without condensation) Storage temperature: -20 ℃~60 ℃ Weight:<15g Life:>10 years
