  1. ZMOD4410 testing conditions and environment compensation

    dear team, thanks for a promising product so far. my goal is to determine human presence in the room using co2 as a proxy. This is why i'm interested in the eCO2 from ZMOD 4410. I Understand the gas sensor is not an NDIR CO2 sensor and will not ...

  1. RRH47000 - NDIR technology and other CO2 detection technologies

    A Nondispersive Infrared (NDIR) sensor is a type of spectroscopic sensor which does not use dispersive elements for separating the target spectrum for sensing from broadband light.  1. NDIR CO₂ SensorsMechanism: Measures CO₂ by analyzing the absorption of infrared light, as CO₂ molecules absorb a specific IR wavelength.Advantages:High ...

  2. RRH47000 - ABC algorithm

    Rough handling, sensor aging, and drastic environmental changes may cause a reduction in accuracy. The sensor incorporates an auto-baseline correction (ABC) feature to automatically compensate for drift. The feature operates as follows:• Initial Baseline Correction: After the sensor is powered on, it continuously monitors the CO2 levels for 24 ...
