Figaro CDM7160 — reference-wavelength NDIR for 24/7 occupancy — model evidence and engineering selection
Current original manufacturer information differentiates optical design, gas span, data interfaces, revision-specific power and calibration assumptions.
| Characteristic | Source-backed detail | Selection consequence |
|---|---|---|
| Optical principle | Single IR source with two separate wavelength-filtered detector elements | One channel reads CO₂-absorbing light; second reference channel compensates source/intensity drift. |
| Constant-occupancy design | Two-wavelength reference avoids relying exclusively on vacant-room 400ppm ABC correction | Important in hospitals, stores and offices occupied day and night. |
| Electrical output | Digital UART or short-range I²C to host microcontroller | I²C is a short-board bus; do not directly wire to distant BAS controller. |
| Power | 60mA peak and ~10mA average in maker overview | Regulator needs peak headroom; consumption is greater than low-power Senseair S12. |
| Physical thickness | 7.5mm low-profile package | Assembly/mounting differs from a tall flow-through optical module. |
| Calibration | Figaro describes factory calibration to known standard CO₂ gas | Actual accuracy/performance band still needs product model-specific current specification. |
| Applications | Continuous ventilation / BEMS/HEMS, hospitals and libraries | A building CO₂ sensor is not an independent personal confined-space detector. |
Firmware, operating environment and calibration
This model’s central engineering distinction is optical reference compensation. Figaro explicitly warns that a single-wavelength sensor using automatic 400ppm correction can drift when a room is never unoccupied, while CDM7160 compares two filtered wavelengths from one source. Do not mistakenly describe it as having two independent IR emitters. Integrators still need pressure/temperature compensation, UART/I²C host design and reference gas calibration verification. The shorter 7.5mm package suits thin wall panels, but proximity to electronics/heat and diffusion opening can bias readings. The source feature page supplies the principle and current/power evidence; detailed product accuracy/order revisions should be independently checked before specification.
