Cubic CM1107
Manufacturer-verified NDIR CO₂ sensor module for OEM air-quality and control applications.
Key Specifications
Product Positioning
Cubic CM1107 is included in Cubic’s NDIR CO₂ sensor portfolio for system integration.
CM1107: Unresolved Technical Fields to Confirm
Important evidence gap: This specific product card does not yet list a numerical measurement range or an accuracy bound. Both values must be obtained from a CM1107-specific datasheet. Do not use the CM1106SL-NS or CM1109 range/accuracy as substitutes merely because they are in the same Cubic NDIR CO₂ category.
Interface definition: “Digital” is not sufficient to connect the sensor to a controller. Verify physical pinout, power supply, serial or bus protocol, sampling cycle and fault signaling against the manufacturer’s CM1107 technical file.
Model-selection gate: Before recommending this unit for a ventilation controller, record the operating concentration, measurement uncertainty at setpoint, response time, calibration/baseline policy, condensation exposure and product lifecycle status.
Document control: Link a dated primary Cubic model sheet when available. Until then the present model record should remain an informational directory entry, not a verified engineering specification.

Cubic CM1107 — dual-optical-channel NDIR; distinguish newer N/NS — sourced technical review
Manufacturer model- and order-code-specific measurements, electrical parameters and lifecycle differences. Avoid extending published values to physically different revisions and newer successor families.
| Specification | Original manufacturer evidence | Design caveat |
|---|---|---|
| Sensing architecture | Dual-beam NDIR CO₂ with optical reference channel | Improves long-term control in buildings lacking a regular clean-air baseline. |
| Original CM1107 default span | 0–5,000ppm, with customized 0–10,000ppm option in maker-model datasheet | Different from current Cubic CM1107N default 0–5k and NS 0–10k product codes. |
| Original maker calibration | ±(50ppm+3% of reading), tested in 0–50°C / 50±10%RH conditions | Newer CM1107N current maker overview lists ±(30ppm+3%); do not transfer the improved code to the legacy CM1107. |
| Reference response | ≤30s T90 for base maker model | Enclosure diffusion can slow real application response. |
| Supply and draw | 3.5–5.5V DC, average <50mA at 1s sample | Different power profile from CM1106SL-NS 37µA every two minutes. |
| Digital/pulse outputs | TTL UART, PWM and I²C by ordered version | No built-in 24V or galvanically isolated RS485/Modbus output. |
| Mechanical body | 33×21.7×18.9mm, around 6.3g | Differs from the thinner CM1106-C single-beam module. |
| OEM lifecycle / revision | Cubic’s current public product overview lists CM1107N/CM1107NS as current dual-beam line | The plain CM1107 generation must not claim current N/NS SKU performance without variant evidence. |
OEM integration, calibration and product lifecycle
Cubic’s dual-beam CO₂ sensing is important for permanently occupied rooms, medical environments and indoor farming where ambient fresh-air ABC assumptions can be false. The archived model-specific CM1107 data give ±(50ppm+3% measured value) and 0–5kppm; Cubic’s current family page lists CM1107N at ±(30ppm+3%) instead. Those grades must remain separate until an exact replacement cross-reference is obtained. Confirm electrical bus framing, pressure correction, reference optical path maintenance and supplied production suffix before installation.
