Описание товара
MH-Z19 carbon dioxide gas sensor (hereinafter referred to as sensor) is a general-purpose, small sensor, the use of non-dispersive infrared (NDIR) principle of the existence of air CO2To detect, with good selectivity, oxygen-free dependence, long life. Built-in temperature compensation; also has a digital output and waveform output, easy to use. TheInfrared sensorIs the mature infrared absorption of gas detection and precision optical design, sophisticated circuit design and the combination of high-performance sensor.
Sensor characteristics
High sensitivity, high resolution, low power consumption Provide UART, PWM waveform and other output methods Temperature compensation, excellent linear output Excellent stability long lasting Anti-water vapor interference, not poisoning
main application
TheInfrared sensorCan be widely used in HVAC and indoor air quality monitoring.
