In continuous operation ExplorIR® NDIR CO₂ sensor delivers two samples/second and consumes only 3.5mW in continuous operation. Even with two carbon dioxide measurements per second delivering low latency and accurate results, it is typically 50 times lower powered than standard NDIR sensors.
CO2 gas sensor designed for HVAC applications, the SCD30, a Non-Diffractive Infra-Red (NDIR) sensor. With a small package volume under 5.6cm3, this CO2 gas sensor can be integrated into HVAC installations. Sensirion has developed a thermopile die based on its air flow sensor technology called CMOSens. This technology allows integration of
MH-Z19Z19C NDIR infrared gas module is a common type, small size sensor, using non non-di spersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, nonnon-oxygen dependent and long life. Built Built-in temperature compensation; and it …
CO2 monitoring can be a cost-effective way to identify spaces with high occupancy and/or poor ventilation, and for actively managing ventilation in a space. Professor Catherine Noakes, who specialises in airborne infections, warns that ‘the numbers are not exact and don’t tell you actual risk from the virus, but they are useful in helping you to improve general ventilation’.
