NDIR Infrared Carbon Dioxide CO2 Sensor
PN:RK-CO2
-
NDIR infrared gas sensor is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO 2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature compensation; and it has UART output and PWM output. It is developed by the tight integration of mature infrared absorbing gas detection technology, precision optical circuit design and superior circuit design.
Feature
Chamber is gold plated, water-proof and anti-corrosion;High sensitivity, low power consumption;Temperature compensation, excellent linear output;Multiple output modes: UART, PWM;ApplicationHVAC refrigeration;Smart home;Air cleaner;Indoor Air quality monitoring;Ventilation system;Technical parameters
