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 ...

RRH47000 - Pressure compensation
The NDIR principle relies on measuring of a gas concentration: The concentration measurement for RRH47000 is defined by target molecules per volume. But this concentration measurement depends also on air pressure. More commonly used is the concentration of CO2 in ppm, which is the ratio of target molecules in ambient ...

RRH47000 - Recommended socket/receptacle
For integrating the module onto a PCB, it is recommended to use a single row receptacle/socket with 2.54 mm pitch. The module will ship with square header pins already soldered and can be plugged into the socket. This will ensure stable electrical connections and secure mechanical attachment ...

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 ...
