Technical details and manufacturing context for Sensor Module

Definition
The Sensor Module is a critical sub-component of the CO2 Sensor Array, responsible for the precise detection and measurement of carbon dioxide levels in various environments. It typically contains the sensing element, signal conditioning circuitry, and communication interface that allow it to function as an integrated unit within the larger array system. This modular design enables scalability, maintenance, and customization of the overall CO2 monitoring solution.
Working Principle
The Sensor Module operates using non-dispersive infrared (NDIR) technology, where an infrared light source emits specific wavelengths that are absorbed by CO2 molecules. A detector measures the intensity of the transmitted light, and the reduction in intensity correlates to CO2 concentration. The module's internal circuitry processes this signal, converts it to digital data, and transmits it to the array's central processing unit.
